the burden of potato chips in a medium-measurement bag is mentioned to be 10 oz. The amount that the packaging machine puts in these baggage is believed to have a traditional model with a mean of oz and a standard deviation of oz.. (round to four decimal areas as necessary.)
a) What fraction of all luggage bought are underweight?
b) one of the vital chips are offered in "discount packs" of 33 baggage. what's the chance that none of the 33 is underweight?
c) what's the chance that the mean weight of the 33 bags is under the cited amount?
d) what's the chance that the mean weight of a 20-bag case of potato chips is beneath 10 oz.?average Distribution:
A random variable X is asserted to be following common distribution with meaneq\mu /eq and variance eq\sigma^2 /eq if its distribution is given as eqf(x|\mu,\sigma^2)=\frac1\sqrt2\pi \sigma^2e^-\frac(x-\mu)^22\sigma^2 \qquad , -\infty \leq X \leq \infty \\ \bar x \space \sim \space N(\mu,\frac\sigma^2n). /eq
general distribution is given with the aid of gauss and at first it is used for modeling the error .
It is assumed that all the herbal phenomenon follows usual distribution.answer and rationalization:
it's given that medium measurement chips is of 10 ounces
The quantity that packaging machine put comply with typical distribution with suggest and commonplace deviation
eq\mu= \\ \sigma= /eq
a) what fraction of luggage are underweight less than 10 ounces
So we need to locate zscore after which the use of NORMSDIST (z) characteristic of MS Excel we will get the probability
eqP(X <10)=P(Z<\ /eq
b) P(None is underweight)=?
None is underweight capability all 33 don't seem to be beneath 10 ounces
Let y denotes variety of underweight
P(None is underweight)=P(Y=0)=?
c) here n=33
So we know that eq\bar x \sim N(\mu ,\frac\sigma^2n) /eq
for this reason eq\bar x /eq observe average distribution with mean and commonplace deviation
eqP(\bar x <10)=P(Z<\ /eq
d) in a similar way right here n=20
for that reason eq\bar x /eq follow common distribution with imply and typical deviation
eqP(\bar x <10)=P(Z<\ /eq

Question: You have three coins. One always comes up heads, one always comes up tails, and one is just a regular coin (has equal change of heads or tails). If you pick one of the coins randomly and flip it twice and get heads twice, what is the chance of flipping heads again?
Answer: 90 percent. If you pick the heads coin the chance of getting the first 2 heads is 100 percent (4/4) and if you pick the fair coin the chance is 25 percent (1/4). So from this, the chance that it is the heads coin is 4/5 and the fair coin 1/5.
Then, if it is the heads coin you will definitely get heads (4/5). If you flip the fair coin it is 1/10 (1/5 * 1/2). Add the probabilities together: 4/5 + 1/10 = 9/10.

Question: There is a farmer who has three sons. Nearing his death, he asked his three sons to find two objects that can fill the room he's in. The one who can deliver will be chosen as his heir. So the oldest son goes to the market to get hay while the middle son go get leaves. The youngest son goes to a shop and buys two things that he put in his pocket. The oldest son's hay only fills half the room, the middle son's leaves fills 2/4 quarters of the room, while the youngest fills the room with his two objects. Question: What are the two objects that the youngest son used to fill the room?
Answer: A match and a candle.

1. The problem statement, all variables and given/known data In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 35 cm thick 350 kg stationary target and emerges with a speed of 850 m/s. The target is free to slide on a smooth horizontal surface. (a) How long is the bullet in the target? (b)What average force does it exert on the target? (c) What is the target's speed just after the bullet emerges? 2. Relevant equations It would be nice to have some more equations, my professor gave the class four pages of equations scribbled in his horrible hand-writing, to help us... I guess. Instead of giving us the basic equations that we can use to plug-in to create our own equations he already solved them all out into the forms he understands, which means we have to un-solve them to try to make sense of them, so really I have no idea what other equations to put here since he has no clear division between which equations go with which section of the book. momentum of system before = momentum of system after ||| Pi=Pf 3. The attempt at a solution I already solved part C using the equation provided. Part A I attempted something that I knew wouldn't work but gave it a try anyway and I know I need part A to solve B so I haven't gotten around to trying to solve B yet. I seem not to be able to resist applying simple mechanics to complex problems just to see if I can knock it out of the way. Anyway I did this to solve for B, it was obviously going to be wrong but I submitted it anyway. B: I tried to say that the DT=0.35m Vavg/DT=??? Then that gave me seconds so I took s-1. Yea, it obviously was just bs, but that is how lost I am.

@johnjohnston Sometimes it surprises me the people who get hooked by those stories. I had a friend try to convince me the other day that universities are effectively shut down because when they try to lecture on certain topics where the thinking has changed, anyone who doesn't like to hear any outdated content will immediately shout down the professor and take over the class.
Like, I'm sure it happens. I'm sure there's some 90 year old professor somewhere who still thinks that Columbus was a pure-and-simple hero and will brook no argument, and I'm sure that professor (and those of his ilk) occasionally get a shout-down. But the idea that this is some sort of epidemic that's destroying the university system is just ridiculous.

If the alignment process is to be reasonably complete, the particle must fall through water for at least time t0. From Stokes' law, Stacey (1963) has shown that the time of fall t of a spherical grain through a depth h of water is given by
d (P-Po)g where (p-p0) is the density difference between the grain and the water and g is the acceleration due to gravity. There is thus some critical height h0 through which the grain must fall for the time t0 to have elapsed. Equating (2.3.34) and (2.3.35), h0 is given by

If R is an associative ring satisfying some mild technical conditions, Beilinson constructs a fiber sequence of spectra identifying the fiber of the map \lim_n K(R/p^n)\rightarrow K(R/p) with a suspension of the ordinary cyclic homology of R, all up to p-completion followed by inverting p. Joint work with Akhil Mathew, Matthew Morrow, and Thomas Nikolaus provides a new proof of this fact using recent advances in the theory of cyclotomic spectra due to Nikolaus and Scholze. I will explain the motivation for this fiber sequence, which has to do with the infinitesimal part of the p-adic variational Hodge conjecture, and then I will give a construction of the fiber sequence and of a more general fiber square.

It is the number that multiplies the unknown variable
Let x be the unknown number. the expression is: x + 10.
It is the coefficient of the unknown variable
v + 6
The algebraic expression is n + 100, where n is the unknown number.
Let the unknown number be x and so the expression is: x+12
As an algebraic expression this is written 2x - 12, where x is the unknown number.
n/6 + 3
x3 + 4x
Let the original number be y Therefore the new number is given by the expression 2y + 6
If x is the unknown variable then it can be: x-16
n+7 or X+7
7x + 2
Let the number be x and so the algebraic expression is: 6x+2
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
Let the unknown number be x and so the algebraic expression is: 2x -13
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
A number increased by four.
k-2.5 An algebraic expression is just using variables (in this case, k) for unknown numbers. Since the question is asking what the number k minus 2.5 is, your answer is k-2.5.
add 3 to a number a number plus 3 the sum of a number and 3 3 more than a number a number increased by 3

In the book we present some of results of the work we have done in theory of classical Cellular Automata (CA) and their appendices during 1969–2013 in truth with considerable pauses. These results at present form essential constituent of the CA problems. In particular, we have studied such problems as the nonconstructability problem in CA, decomposition of global transition functions in CA, extremal constructive possibilities, complexity of finite configurations and global transition functions, parallel formal grammars along with languages defined by CA, the modelling problem in the classical CA, computer simulation of CA, certain applied aspects of CA, etc. At present, the CA problems is a rather well developed independent sphere of the mathematical cybernetics which has considerable field of numerous appendices. At that, with the equal right the CA problems can be considered as a component of such fields as discrete mathematics, the discrete parallel dynamic systems, complex systems and some others. In our opinion the book will present an indubitable interest for students, post–graduates and persons working for doctor's degree of the appropriate faculties of universities.

Number Theory Quotes (6 quotes)
Gauss once said, “Mathematics is the queen of the sciences and number theory the queen of mathematics.” If this is true we may add that the Disquisitions is the Magna Charter of number theory.
I count Maxwell and Einstein, Eddington and Dirac, among “real” mathematicians. The great modern achievements of applied mathematics have been in relativity and quantum mechanics, and these subjects are at present at any rate, almost as “useless” as the theory of numbers.
Mathematics is the queen of the sciences and arithmetic [number theory] is the queen of mathematics. She often condescends to render service to astronomy and other natural sciences, but in all relations, she is entitled to first rank.
Number theorists are like lotus-eaters—having tasted this food they can never give it up.
Since the examination of consistency is a task that cannot be avoided, it appears necessary to axiomatize logic itself and to prove that number theory and set theory are only parts of logic. This method was prepared long ago (not least by Frege’s profound investigations); it has been most successfully explained by the acute mathematician and logician Russell. One could regard the completion of this magnificent Russellian enterprise of the axiomatization of logic as the crowning achievement of the work of axiomatization as a whole.
When Ramanujan was sixteen, he happened upon a copy of Carr’s Synopsis of Mathematics. This chance encounter secured immortality for the book, for it was this book that suddenly woke Ramanujan into full mathematical activity and supplied him essentially with his complete mathematical equipment in analysis and number theory. The book also gave Ramanujan his general direction as a dealer in formulas, and it furnished Ramanujan the germs of many of his deepest developments.

Award Helpmate twomovers 1998
In 1998, there were 88 problems in the Probleemblad helpmate column; among them, two had been published in other magazines before and were thus not eligible for distinctions.
I would like to thank Peter van den Heuvel for asking me to act as ajudge in this renowned magazine and Hans Gruber for helping me to find anticipations and problems that offer interesting comparison. Judging an informal helpmate tourney is a lot about comparing the entries to what has been done before, maybe more so than in other genres, as so many helpmate problems have been published recently that it's almost always possible to find something. As it has become typical for helpmate informal tourneys, 1 got a great deal of assistance from the solvers, criticising constructions and providing versions and problems for comparison; their comments explain why 1 did not include several interesting problems in the award.
In addition, the following problems have been excluded because of anticipations, better predecessors or thematical flaws:
I found the level ofthe remaining problems quite high, which explains the rather high percentage of distinctions.
- H054 by Jevgeni Markov is anticipated by Matti Myllyniemi (diagram A) ;
- H073 by Toma Garai: cf. Jean-Marc Loustau (diagram B) ;
- H080 by Tode Ilievski: cf. Attila Benedek (diagram C) with the additional paradox that the originally pinned white piece gives the mate;
- H088 by Nikolai Nagnibida: I don't consider the problem given in PB 1998-5, p. 191 to be an anticipation since the first black moves of H088 add strategy. I didn't award it, though, because of its overly heavy construction and its logical impurity: if the black Rook and black Bishop moved to d3 from the side (c2/f1), we'd have dual-avoiding blocks instead of blocks that happen to interfere. See my article in idee &form 62/1999 for a longer discussion;
- H100 by Gennadi Tsjumakov: cf. Frank Fiedler (diagram D) ;
- H129 by Aleksandr Pankratjev & Dieter Muller: cf. Zoltan Laborczi (diagram E) .

Nice functional change ofwhite Rook and Bishop both in the set play and the solution (Zilahi). 1 also like that the selection of the black pieces capturing at c2 and e7 is based on negative effects of the Knight moves. All this is added value to Janos Csak (diagram F) , and compensates well for the not so pretty position.

Some time ago, 1 awarded the similar looking Gabor Cseh (diagram G) the Ist prize. The play in H064 may look less ambitious, but the pin-mates are more subtle than what we find in Gabor's problem.

Usage of white battery pieces in newly created batteries as required in the WCCT. Much to my surprise, there is only one WCCT entry (Manne Persson, 12th rank) with this combination and a black half-pin; H099 has more interesting black play.

The author has created several examples of this cycle, but (to my knowledge) not so far with the entire play on a direct third-battery. One could argue that Miroslav Stosic (diagram H) contains double the content of H111 (with much less effort!), but the avoidance of the other variation in each solution is the essence of H111.

H125 is thematically denser than the problems printed for comparison with its solution (PB 99-2, p.57): there are only thematical white pieces so that we have a Zilahi. 1 don''t give a prize to H125 because Arefjev's sacrifices are more subtle.

From a thematical point of view, this problem may not be on the level of its neighbours in this award. But 1 like such neat realisations where there isn't a single non-thematic piece. There is a serious danger of anticipation, but 1 haven't found an example with anticipatory unpins.

5ª MO - Tode Ilievski, H112
1 have always been fascinated by problems where a white line piece has to be replaced by another one. Here we have an example where both replacements occur on the same line, which allows the replaced piece not to be the Queen. 1 didn't take into consideration the fact that the thematic line is masked, which in theory could make the solver's task a little bit more difficult. In Hl 12, the masking is artificial since the white Bishop could as well stand on h5 in the diagram position, which, by the way, looks heavy, but 1 can't find any obvious draw-backs in the construction.

Interferences of the black Bishop that cause the black King to be 'pseudo-unpinned'. In strategical two-movers 1ike this, I think it's important for the thematical moves to be purely motivated. But, as pointed out by a solver, in H110(a), the black Rook has two (or maybe one and a half...) reasons for interfering with the Bishop al (check and control of f6).

If l hadn't known of the Problemkiste problem provided by a solver in PB 1998-4 p. 148, 1 would have awarded H068 higher. 1 don't consider it to be an anticipation, but where we 'merely' have King moves in H068, there is additional strategy (black anticipatory self-pin) in Problemkiste.

The Java theme in helpmate form; 1 must confess that 1 have absolutely no idea if there are earlier realisations. This one is not too much to my taste, partially because the locked out white Queen has to be brought into play which made the solutions rather obvious.

There are many two-phase problems with anticipatory self-pins, but a lot of them don't show double-pin mates, of course. Daniel de Irezabal is interesting to compare (diagram I) ; I prefer H066 because it substitutes exchanged functions of the black pieces for the twinning mechanism.

Two white Knight-wheels seem to be new, and they are realised with optimal white economy here. The author seems to have been interested in the fact that all the first moves are executed by one Knight and all the mating moves by the other. Luckily, he didn't have to pay for this with additional black material; every black piece contributes to at least one mate.

Tempo captures with exchange off functions (Zilahi); the interceptions in Black's second move are well integrated. Everything except the Zilahi has been shown in the equally crowded bemd ellinghoven, feenschach 1991 (diagram J) , where strategical means are employed to prevent the black Knights from losing the tempo.

Interesting play, but I don't understand why the author chose to pin the white Rook and Bishop in the diagram position. The author has shown the same strategy in Mat-Pat 1994 (diagram L) , but here, the play is much more obvious because of the white Pawns on the seventh line.

|A "✓" indicates that the column property is required in the row definition.|
For example, the definition of an equivalence relation requires it to be symmetric.
All definitions tacitly require transitivity and reflexivity.
In mathematics, a relation R on a set X is antisymmetric if there is no pair of distinct elements of X each of which is related by R to the other. More formally, R is antisymmetric precisely if for all a and b in X
- if R(a, b) with a ≠ b, then R(b, a) must not hold,
- if R(a, b) and R(b, a), then a = b.
(The definition of antisymmetry says nothing about whether R(a, a) actually holds or not for any a.)
The divisibility relation on the natural numbers is an important example of an antisymmetric relation. In this context, antisymmetry means that the only way each of two numbers can be divisible by the other is if the two are, in fact, the same number; equivalently, if n and m are distinct and n is a factor of m, then m cannot be a factor of n. For example, 12 is divisible by 4, but 4 is not divisible by 12.
The usual order relation ≤ on the real numbers is antisymmetric: if for two real numbers x and y both inequalities x ≤ y and y ≤ x hold then x and y must be equal. Similarly, the subset order ⊆ on the subsets of any given set is antisymmetric: given two sets A and B, if every element in A also is in B and every element in B is also in A, then A and B must contain all the same elements and therefore be equal:
A real-life example of a relation that is typically antisymmetric is "paid the restaurant bill of" (understood as restricted to a given occasion). Typically some people pay their own bills, while others pay for their spouses or friends. As long as no two people pay each other's bills, the relation is antisymmetric.
Partial and total orders are antisymmetric by definition. A relation can be both symmetric and antisymmetric (in this case, it must be coreflexive), and there are relations which are neither symmetric nor antisymmetric (e.g., the "preys on" relation on biological species).
- Reflexive relation – A binary relation over a set in which every element is related to itself
- Symmetry in mathematics – Symmetry in mathematics

This fun game can be run as a math center or with partners to practice mixed number and fraction equivalency. Students will love the game format while they model fraction equivalency.
1. Students will represent equivalency using a model diagram, repeated addition, and multiplication with addition.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?.

Hearthstone's patch 16.4 is live, bringing new minions to the Battlegrounds mode as well as a couple of new Heroes. Of these new minions, sixteen of the eighteen are completely new to Hearthstone altogether and will be exclusive to Battlegrounds. \n \nGalakrond and Reno Jackson will be joining us as Heroes for the new patch, joining the five original Dragon Aspects of Alexstrasza, Neltharion\/Deathwing, Ysera, Nozdormu, and Malygos. With so many dragons as heroes, it only makes sense that the minions they're summoning are going to be dragons as well! \n \nGalakrond's hero power is Galakrond's Greed, a 1-cost power that replaces a minion in the tavern with a minion from a higher Tavern Tier. Reno Jackson's is significantly more expensive, working as a 4-cost that turns a friendly minion Golden once per game. \n \n \n \nThe new Dragon minions are as follows: \n \n \tDragonspawn Lieutenant - Tier 1 2\/3 with taunt \n \tRed Whelp - Tier 1 1\/2 with "Start of Combat: Deal 1 damage per friendly Dragon to one random enemy minion." \n \tGlyph Guardian - Tier 2 2\/4 with "Whenever this attacks, double its Attack." \n \tSteward of Time - Tier 2 2\/4 with "When you sell this minion, give all minions in Bob's Tavern +1\/+1." \n \tWaxrider Togwaggle - Tier 2 1\/2 with "Whenever a friendly Dragon kills an enemy, gain +2\/+2." \n \tUnstable Ghoul - Tier 2 1\/3 with taunt, "Deathrattle: Deal 1 damage to all minions." \n \tBronze Warden - Tier 3 2\/1 with Divine Shield, Reborn. \n \tHangry Dragon - Tier 3 4\/4 with "At the start of your turn, gain +2\/+2 if you won the last combat." \n \tDrakonid Enforcer - Tier 4 3\/6 with "After a friendly minion loses Divine Shield, gain +2\/+2." \n \tHerald of Flame - Tier 4 5\/4 with "Overkill: Deal 3 damage to the left-most enemy minion." \n \tCobalt Scalebane - Tier 4 5\/5 with "At the end of your turn, give another random friendly minion +3 Attack". \n \tMurozond - Tier 5 5\/5 with "Battlecry: Add a minion from your last opponent's warband to your hand." \n \tTwilight Emissary - Tier 5 6\/8 with Taunt, "Battlecry: Give a friendly Dragon +3\/+3." \n \tRazorgore, the Untamed - Tier 5 2\/4 with "At the end of your turn, gain +1\/+1 for each Dragon you have." \n \tHoly Mackeral - Tier 6 8\/4 with "After another friendly minion loses Divine Shield, gain Divine Shield." \n \tImp Mama - Tier 6 6\/8 with "Whenever this minion takes damage, summon a random Demon and give it Taunt." \n \tKalecgos, Arcane Aspect - Tier 6 2\/8 with "After you play a minion with Battlecry, give your Dragons +1\/+1." \n \tNadina the Red - Tier 6 7\/4 with "Deathrattle: Give your Dragons Divine Shield." \n \nAnd those are all the minions joining the Battlegrounds! With the exception of Holy Mackeral and Imp Mama, each of these minions is either a Dragon or interacts with Dragon minions in a way that affects playstyle. Make sure you tune into the Twitch Drops between February 26th and February 29th to claim your free Descent of Dragons packs so you can start adding some dragons to your hand as fast as possible.

A robust folk theorem for the repeated prisoner's dilemma
Journal of Economic Theory, 102, (1), . (doi:10.1006/jeth.2000.2774).
Full text not available from this repository.
We prove the folk theorem for the Prisoner's dilemma using strategies that are robust to private monitoring. From this follows a limit folk theorem: when players are patient and monitoring is sufficiently accurate, (but private and possibly independent) any feasible individually rational payoff can be obtained in sequential equilibrium. The strategies used can be implemented by finite (randomizing) automata. Journal of Economic Literature Classification Numbers: C72, C73, D82.

4. A Line is that which has length merely, and may be straight or curved.
5. A Straight Line, or, as it is sometimes called, a right line, is the shortest, line that can be drawn between two given points. Straight lines are generally designated by letters or figures at their extremities, as A B, Fig. 1.
6. A Curved Line is one which changes its direction at every point, or one of which no portion, howFig. 1 - A S raight Line. ever small, is straight. It is therefore longer than a straight line connecting the same points. Curved lines are designated by letters or figures at their extremities and at intermediate points, as A 15 C or D E F, Fig. 2.
Fig. 2 - Curved Lines.
7. Parallel Lines arc those which have no inclination to each other, being everywhere equidistant. A B and A1 B1 in Fig. '3 are parallel straight Hues, and can never meet though produced to infinity. C D and C D' are parallel curved lines, being arcs of circles which have a common center.
Fig. 3. - Parallel Lines.
8. Horizontal Lines are lines parallel to the horizon, or level. A Horizontal Line in a drawing is indicated by a line drawn from left to right across the paper, as A B in Fig. 4.
Fig. 4. - Names of Lines by Direction.
9. Vertical Lines are lines parallel to a plumb line suspended freely in a still atmosphere. A Vertical Line in a drawing is represented by a line drawn up and down the paper, or at right angles to a horizontal line, as E C in Fig. 4.
10. Inclined or Oblique Lines occupy an intermediate between horizontal and vertical lines, as C D,
Fig. 5. - Perpendicular Lines.
Fig. 4. Two lines which converge toward each other and which, if produced, would meet or intersect, are said to incline to each other.
11. Perpendicular Lines. - Lines are perpendicular to each other when the angles on either side of the point of meeting are equal. Vertical and horizontal lines are always perpendicular to each other, but perpendicular lines are not always vertical and horizontal, but may be at any inclination to the horizon, provided that the angles on either side of the point of intersection are equal. In Fig. 5, C F, D II and E G arc said to be perpendicular to A B. Also in Fig. 6,
Fig. 6. - Perpendicular Lines.
C D and E F are perpendicular to A B. Lines perpendicular to the same line are parallel to each other, as C F and D H, Fig. 5, which are perpendicular to A B.
12. An Angle is the opening between two straight lines which meet one another. An angle is commonly designated by three letters, the letter designating the point in which the straight lines containing the angle meet being between the other two letters, as the angle ECD, Fig. 4.
Fig. 7. - Angles.
13. A Right Angle. - When a straight line meets another straight line so as to make the adjacent angles equal to each other, each angle is a right angle, and the straight lines are said to be perpendicular to each other. (See C B E or C B D, Fig. 7.)
14. An Acute Angle is an angle less than a right angle, as A B D or A B C, Fig. 7.
15. An Obtuse Angle is an angle greater than a right angle, as A B E, Fig. 7. firms and Definitions. 3

benchmark fractions mean
What benchmark fraction is closest to each point in the letter E
It depends what the benchmark is!
By Benchmark it means what is closer for example the benchmark of 24% is 25%.
yes 2/4 is because it is equivalent to 1/2 which is a benchmark fraction.
112 is an integer and so there is no sensible way to represent it as a fraction - whether benchmark or otherwise.
18/1000 = 9/500
you put it over 1 for example: to make the number 5 into a benchmark fraction, you would turn it into 5/1

Astronomical effects in Moonrise/Moonset calculations
Among the other visible celestial objects the Moon is one of the most difficult to calculate.
The are a number of reasons:
The moon is affected by the gravity of the Earth and the Sun;
it is a very close objects so we need to take into account the parallax effect;
it is a big object in terms of angular size (true for the Sun as well);
the refraction effect due to the Earth’s atmosphere (true for all celestial objects).
Let’s take into account all these effect.
First of all, define some of the values we will use below:
london :: GeographicCoordinates london = GeoC 51.5074 (-0.1278) dt :: LocalCivilTime dt = lctFromYMDHMS (DH 1) 2017 7 6 10 30 0 today :: LocalCivilDate today = lcdFromYMD (DH 1) 2017 7 6 jd :: JulianDate jd = lctUniversalTime dt -- distance from the Earth to the Moon in kilometres mdu :: MoonDistanceUnits mdu = moonDistance1 j2010MoonDetails jd -- MDU 0.9550170577020396 distance :: Double distance = mduToKm mdu -- 367109.51199772174 -- Angular Size angularSize :: DecimalDegrees angularSize = moonAngularSize mdu -- DD 0.5425033990980761
To calculate refraction we can use
refract function from
Data.Astro.Effects module. It takes the observed altitude, temperature in degrees centigrade and barometric pressure in millibars.
The observed altitude is always 0 if we calculate rise and set, good reasonable values for temperature and barometric pressure are 12 and 1013 respectively:
Angular size correction is simple:
The refraction effect and angular size correction alter the apparent height of the object, we will use sum of them as a parameter of
Let’s calculate the Parallax effect now.
parallax function of
Data.Astro.Effects module “corrects” given equatorial coordinates, apart the coordinates of the celestial object it takes geographic coordinates of the observer and height above sea-level of the observer measured in metres, distance from the celestial object to the Earth measured in AU and the Universal Time:
moonPosition2 function (which takes the parallax effect into account) is available in astro library since version 0.4.2.0.
Now let’s summarise everything we talked about and calculate Moonrise and Moonset time:
module Main where import Data.Astro.Time.JulianDate import Data.Astro.Coordinate import Data.Astro.Types import Data.Astro.Effects import Data.Astro.CelestialObject.RiseSet import Data.Astro.Moon import Data.Astro.Moon.MoonDetails london :: GeographicCoordinates london = GeoC 51.5074 (-0.1278) dt :: LocalCivilTime dt = lctFromYMDHMS (DH 1) 2017 7 6 10 30 0 today :: LocalCivilDate today = lcdFromYMD (DH 1) 2017 7 6 jd :: JulianDate jd = lctUniversalTime dt -- distance from the Earth to the Moon in kilometres mdu :: MoonDistanceUnits mdu = moonDistance1 j2010MoonDetails jd distance :: Double distance = mduToKm mdu -- Angular Size angularSize :: DecimalDegrees angularSize = moonAngularSize mdu position :: JulianDate -> EquatorialCoordinates1 position jd = moonPosition2 j2010MoonDetails distance london height jd where distance = moonDistance1 j2010MoonDetails jd height = 20 verticalShift :: DecimalDegrees verticalShift = r + s where r = refract 0 12 1012 s = 0.5 * angularSize riseSet :: RiseSetMB riseSet = riseAndSet2 0.000001 position london verticalShift today main :: IO () main = print riseSet -- RiseSet -- (Just (2017-07-06 18:48:44.5949 +1.0,DD 120.13250305991525)) -- (Just (2017-07-06 03:09:54.7904 +1.0,DD 241.7780054101992))
timeamddate.com gave the following results:
Moonrise: 18:49, (120°)
Moonset: 03:10, (242°)
Those perfectly match with our results.

About this book
A mathematical theory is introduced in this book to unify a large class of nonlinear partial differential equation (PDE) models for better understanding and analysis of the physical and biological phenomena they represent. The so-called mean field approximation approach is adopted to describe the macroscopic phenomena from certain microscopic principles for this unified mathematical formulation. Two key ingredients for this approach are the notions of “duality” according to the PDE weak solutions and “hierarchy” for revealing the details of the otherwise hidden secrets, such as physical mystery hidden between particle density and field concentration, quantized blow up biological mechanism sealed in chemotaxis systems, as well as multi-scale mathematical explanations of the Smoluchowski–Poisson model in non-equilibrium thermodynamics, two-dimensional turbulence theory, self-dual gauge theory, and so forth. This book shows how and why many different nonlinear problems are inter-connected in terms of the properties of duality and scaling, and the way to analyze them mathematically.

Missing information needed to answer this question and figure out the correct play:
2. Blind level
3. What's your position
4. How much was the raise
5. How much is your 3bet
6. How much is his 4bet shove (chipstacks)
7. What information do you have on your opponent. Is he loose, tight, aggro, passive?
8. How many players are in the tournament
9. How many are left
The most important information though is how deep your chipstack is. If youre shortstacked, then yes, put it in the middle mist of the time. If youre not short stacked then most of the time don't.

Given a sequence of scalars (cn) and a sequence of distinct points (xn) in (a, b), define f(x) = cn if x = xn for some n, and f(x) = 0 otherwise. Under what condition(s) is f of bounded variation on [a,b]?
Vbaf = supp([tex]\Sigma[/tex]lf(ti) - f(ti-1)l< +inf, then f is of Bounded Variation.
The Attempt at a Solution
My understanding of the question is that we have points at x in a vertical line and points along y=0 at every other value of x. So the only way that this function is of bounded variation is if there is a supremum of the constants so that they can't go on vertically to infinitum. If we merely say that they are bounded above we won't have bounded variation, so we must say that the supremum is a member of the set of cn's.

Fans, pumps, and compressors are machines used to control heat and fluid transfer. Fans are used to cool and ventilate and move gases in a less controlled way than compressors, and they are rated to move a certain number of cubic feet per minute (CFM). For example, buildings have a requirement for the number of CFMs of air circulation, based on occupation and the building's use. Pumps control the flow of a fluid (typically a liquid) by increasing the pressure upon it; they are found at the beginning of a run of piping through which the fluid is being directed. Compressors are typically used with gaseous fluids; they also use pressure increase to direct material through a pipe. Compressors also compress the volume of gases.

math

The nine dot problem is a classic lateral thinking exercise that gained widespread popularity in the 1970's and 80's. Participants are presented with a set of dots arranged in a 3x3 grid and challenged to connect all nine dots, without lifting their pencil from the paper, using the fewest possible number of straight lines.
Copy the simple diagram below onto a piece of paper and give the puzzle a try for yourself before reading any further.
The solution requires one to "think outside the box" and while some contend that the nine dot problem served as the inspiration for this popular turn of phrase, others point to a cognitive performance test from 1945 known as Duncker's candle problem.
In Duncker's test, participants are presented with a candle, a book of matches and a box full of push pins. The challenge is to affix the candle to the wall in such a way that when the candle is lit, the wax will not drip onto the table... The solution requires the functional use of the box which at first, may seem to be included simply to contain the push pins.
Whether or not the nine dot problem is in fact the original inspiration for the cliched metaphor, the puzzle itself certainly pre-dates the phrase. The first known publication was in Sam Loyd's classic Cyclopedia of Puzzles, 1914.
Though, in a 1959 compendium of Sam Loyd's work, Martin Gardner described this particular puzzle as a "classic geometrical challenge" so the nine dots likely predate Loyd's eggs. The enduring aspect of the puzzle is that it highlights the way our minds tend to impose unnecessary limitations upon methods of attacking problems. For those unfamiliar, the most popular solution to the puzzle is depicted below.
Clearly, this solution requires one to "think outside" the "box" that is formed by the nine dots but if we are to fully embrace the idea of "outside the box" thinking, why stop there? Here's a way to solve the puzzle using only three straight lines.
This solution is even further "outside the box" than the first. But what if the box is not the square described by the nine dots but rather, the piece of paper the puzzle is printed on? If we think outside of THAT box, it is possible to solve the puzzle using only one straight line.
Even without manipulating the paper, there is still another way to solve the puzzle using only one straight line.
Of course, the line is so long that it circles the earth twice but it is straight nonetheless and solves the puzzle successfully. So perhaps the greatest lesson of the nine dot problem is not to "think outside the box" but rather, that when it comes to truly creative problem solving, there is no box.

They are prerequisites here.
Here we study methods that can be used to determine
whether a number is evenly divisible by other numbers.
These are shortcuts for testing a number's factors
without resorting to division calculations.
The rules given below transform a given number's divisibility
by a divisor to a smaller number's divisibility by the same divisor.
If the result is not obvious after applying it once,
the rule should be applied again to the smaller number.
We present the rules with examples, in a simple way,
to follow, understand and apply.
We provide the rules for all the single digit divisors
and prime divisors upto 47 and above and a general method which is simple to use.

Divisibility Rule for 6
A number is divisible by 6, if the number is divisible by both 2 and 3.
check whether the Numbers in examples under divisibility by 3,are divisible by 6 or not.
Here, we have to first check whether the number is even or odd. If it is odd, then it is not divisible by 6.
If it is even, then check for the divisibility by 3. If it is divisible by 3,
then it is divisible by 6. Otherwise not.
In the above examples under divisibility by 3,
Numbers in Examples 1, 2, 3 are odd numbers and hence are not divisible by 6.
Out of Numbers in remaining Examples 4 and 5,
Number in Example 5 is not divisible by 3.
∴ only Number in Example 4 is divisible by 6.

Progressive Learning of Math : Divisibility Rules
Recently, I have found a series of math curricula
(Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.
This series is very different and advantageous
over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.
These build a student’s new knowledge of concepts
from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.
These also provide teachers and parents with lessons
on how to work with the child on the concepts.
The series is low to reasonably priced and include
Elementary Math curriculum and Algebra Curriculum.

Has anyone been successful self studying mathematics and physics? By successful I mean to achieve your goals to study and have firm understanding in the subjects. How did you do it? How long did it take?
It should give you some thoughts, such that you can judge by yourself how far it is from where you stand to where you want to go to. This depends on so many factors, that it is impossible to answer it in general. What's true for one person doesn't have to be true for another.

Newton’s Laws of Motion: These are the fundamental physics laws used in our real life on a day-to-day basis. Newton’s law of Motion is the three laws that deal in a relationship between the motion of an object and the force acting on it. In these three newton’s laws, he explained what happens when a body is at rest or in motion or forced by an external force to bring the body in motion with their reactions. Here in this article, you will learn more about Newton’s Laws of Motion and Its Real-Life Applications.
Isaac Newton, the great scientist, is the one who explains these Laws of Motion. Newton used these laws to explain and investigate the motion of a body and objects and systems, which laid the base of many important physics topics. Here learn the three important newton’s laws of motion, definition, formula, and the applications used in real life.
Newton’s Law of Motion and Its Real-Life Applications
Here Learn the three Newton’s Law of Motion which is well explained. Please read all three Laws and understand the concept of their usage in our daily life. These laws do help us in day-to-day life as well as helps us in learning many topics of Physics and Mechanics, which derives from these Newton’s Laws of Motion.
Newton’s First Law of Motion: The Law of Inertia
Newton’s first law of motion states that an object cannot start, stop, or change direction by itself. It needs some external force to cause a change in motion. This property of massive bodies to resist changes in their state of motion is called inertia. Newton’s first law is also known as the law of inertia.
Statement: A body remains at rest or moves straight line (at a constant velocity) unless acted upon by an external force.
Real-life application: Shake up that bottle of ketchup! When you shake that bottle, you bring the bottom down, then suddenly you stop. It is inertia that causes the ketchup to come out of the bottle.
Newton’s Second Law of Motion
The second law of motion discusses what happens to an object when acted upon by an outside force. The Newton Second law of motion states that the force applied to the body is the same as the product of its mass and acceleration.
Statement: Newton’s 2nd law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Newton’s Law of Motion Formula: F=ma
Real-life application – Your friend weighs less than you, but you both walk, exerting the same amount of force. Your friend will go a good deal faster than you because the acceleration used by them would undoubtedly be higher.
One of the main reasons people constantly try to reduce the mass of objects is to increase their speed and acceleration. All of the factors affect each other. If something has much more mass, then exerting more force will make it move faster.
Newton’s Third Law of Motion
In this Newton’s Third Law of Motion, we discuss the action and reaction with their use in daily life.
Statement: For every action, there is an equal and opposite reaction. If one body exerts a force on the second body, then the second body exerts an equal force on the first body.
Real-life application – Hitting the Wall with Your Fist! There are two forces, your force and the other is an equal and opposite force applied by the wall on the fist. Hence, the harder you hit the wall, the more force is exerted on your fist by the wall; this is why you get hurt more. So don’t hit the wall because you will get yourself hurt.
Newton’s Laws of Motion Questions & Answers
Question 1: A box of mass 2 kg and a force of 20 N is acting on it in the positive x-direction, and a force of 30 N in the negative x-direction, then find its acceleration?
Answer: To find acceleration, we need to calculate the net force.
Fnet = 20 N – 30 N = -10 N
Mass = 2kg
As we know, F=ma so to find acceleration, we have to divide the force by mass as per formula a=F/m
Question 2: While driving to work, Ram always keeps his purse in the passenger seat. By the time he reaches the office, the purse has fallen in front of the passenger seat. So why it happens?
Answer: We can explain it in terms of Newton’s first law of motion. The purse, because of inertia, travels forward with a car until acted by an external force. In this case, the force of the car floor is made the purse fall from the seat.
Question 2: Calculate the net force required to give an automobile of mass 1500 kg an acceleration of 5 m/s2
Answer: We calculate the force using the following formula F=ma
Given details are m= 1500 kg & a=5 m/s2
F=ma, So, F= 1500 * 5 =7500N
So the force required is 7500N
FAQs Related to Newtons Law and its Real-Life Applications
A. Newton’s laws of motion relate an object’s motion to the forces acting on it. In the first law, an object will not change its movement unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. Finally, when two bodies interact in the third law, they apply forces of similar magnitude and opposite direction.
A. Newton’s laws of motion are essential because they are the foundation of classical mechanics, one of the main branches of physics. Mechanics is the study of how objects move or do not move when forces act upon them.
A. The great scientist Sir Isaac Newton discovered the three laws of motion. He also discovered Newton’s Law of Gravitation.
A. The motion of a ball falling through the atmosphere or a model rocket launched into the atmosphere are excellent examples of Newton’s 1st law of motion.
You hit a wall with a certain amount of force, and the wall returns that same amount of force, which is an example of Newton’s 3rd law.
A. The laws state that:
(1) Every object moves in a straight line unless acted upon by force.
(2) The object’s acceleration is directly proportional to the net force exerted and inversely proportional to the object’s mass.
(3) For every action, there is an equal and opposite reaction.

answer : the density of metal is, 2.7 g/ml
solution : given,
mass of metal = 4.86 g
volume of initial water = 15.5 ml
volume of rose water = 17.3 ml
first we have to calculate the volume of metal.
volume of metal = volume of rose water - volume of initial water
volume of metal = 17.3 - 15.5 = 1.8 ml
now we have to calculate the density of metal.
formula used :
now put all the given values in this formula, we get the density of metal.
therefore, the density of metal is, 2.7 g/ml

An introduction to analytic number theory, fall 2014
What is going on?
The lectures have ended. Thanks a lot for all participants!
There is still an instruction class on Friday 5.12, and the last exercise class is on Friday 12.12.
Some material of past lectures
Basic knowledge of elementary number theory and algebra. Complex analysis I, Complex analysis II (only selected parts of this course, which can be studied by one self during the lectures if needed), basic measure and in integration theory.
Weeks 37-42 and 45-49, Tuesday 10-12 and Wednesday 9-12 in room C123. Some extra lecture times or changes in the times will be agreed on together during the course.
The course will be passed by returning in a written form an appropriate number of given exercises (or by an exam/oral test if separately agreed with the lecturer). If X stands for the maximum number of points one may get by returning exercises, to pass the course one needs X/2 points. There are no different grades, just passed on non-passed.
The course proceeds somewhat rapidly to advanced things. However, to pass the course it is not required to master all the material, which allows us to touch many fascinating parts of the basic theory.
A good and very readable introduction to analytic number theory is Tom Apostol: Introduction to Analytic Number Theory, (1976) Springer-Verlag, New York. ISBN 0-387-90163-9

Exercise and instruction classes
The excercise classes are as follows:
Class 1 on Friday 10.10.
Class 2 on Friday 31.10.
Class 3 on Friday 21.11.
Class 4 on Friday 12.12.
In (almost all) of the rest of Fridays one has instruction classes. They are held on Fridays 19.9., 26.9., 17.10., 7.11., 14.11, 28.11 and 5.12.
The idea of a instruction class is that Jääsaari is present and can discuss the exercise/course material.

Improve Speed of Matrix Multiplication by Taking Advantage of GPUArray
26 views (last 30 days)
I actually want to improve the speed of the multiplication of matrix A (m-by-n) and vector x (n-by-1) using GPUArray. Using:
gpuA = gpuArray(A);
gpux = gpuArray(x);
gpuC = gpuA * gpux
C = gather(gpuC)
didn't give me the needed improvement in speed. Any ideas on how I can achieve this?

Joe Biden will win the US election according to a technique used in finance to predict factor returns and the correlation of stock and bond returns.
The past as a prologue: how to forecast presidential elections, a MIT working paper, co-authored by MIT’s Mark Kritzman and Dave Turkington and Megan Czsasonis from State Street, uses a model that correctly predicted the outcomes of the past five presidential elections. It is now predicting a strong Democratic victory for 2020, with a Democratic loss within a confidence band of one standard deviation. Interestingly, the technique correctly predicted the 2016 election, which the polls failed to do.
The authors apply a novel forecasting technique called Partial Sample Regression which measures the statistical relevance of past elections, and then employs an “obscure mathematical equivalence” – that the prediction from a linear regression equation equals a relevance-weighted average of the values for the dependent variable. It uses this to forecast election outcomes from a subsample of prior relevant elections.
The technique predicts the elections in a mathematically formal way and uses no poll data.
“The essence of our methodology is to measure the relevance of historical elections in a statistically rigorous way. We then rely on an obscure mathematical equivalence to form predictions from the more relevant elections,” the authors say.
“When political scientists or pundits forecast presidential elections, they often analyse past elections for clues about upcoming elections. But they don’t treat all past elections alike. They judge some to be more relevant than others. This behaviour is true in general when we try to predict an outcome based on prior experiences. We look for those events that bear some resemblance to current conditions. We apply this concept to predict the outcomes of presidential elections, but we do so in a mathematically formal way.”
The authors then add to this the less obvious component of “relevance”.
“We consider the unusualness of the past experiences. The intuition is that unusual occurrences are more informative than common occurrences, which simply might be a manifestation of noise in the data. Once we identify a subsample of relevant historical elections, we invoke an obscure mathematical equivalence. The prediction from a linear regression equation equals a weighted average of the past values of the dependent variable in which the weights are the relevance of the values for the independent variables. We apply this equivalence to our relevant subsample of political, geopolitical, and economic data to form our predictions.”
The methodology used to predict election results is similar to that used by Kritzman and Turkington and their co-authors Ding Li and Grace Qiu from GIC in the paper, Portfolio Choice with Path Dependent Preferences, which is forthcoming in the Financial Analysts Journal. That study, which revolutionises scenario analysis by reorienting it towards a path rather than a single period outcome, finds that a U-shaped recovery is the most likely economic outcome in the US for the next two years, but stagflation has a higher than anticipated chance of occurring.

how to generate combination through specific matrix dimension?
2 views (last 30 days)

I have a matrix (128, 128, 20, 8) the 4th diminution is 4 pairs; how can I generate a combination of that 4th diminution as 4-pairs by picking 2 each time?
Roger Stafford on 23 Feb 2018
As James has stated, your question is not clear. I'm going to make a very wild guess as to your meaning. If it is wrong, as is likely, perhaps the method I show will give you some ideas of how you can achieve what you actually want.
Let your original 128x128x20x8 matrix be called A. Let the matrix you want to create be called B. I will suppose that your pairings in the 4th dimension of A are 1 and 2, 3 and 4, 5 and 6, 7 and 8. You then want to take all possible combinations of two pairs out of these four: 1,2,3,4 then 1,2,5,6 then 1,2,7,8, then 3,4,5,6 and so forth. This will give you a size of 4*6 = 24 at the fourth dimension.
C = nchoosek(1:2:7,2); % Choose 2 out of 4
n = size(C,1); % n = 4!/2!/2! = 6 in this case
B = repmat(zeros(size(A)),1,1,1,n/2); % B will have size 8*6/2=24 at 4th dimension
for ix = 1:n
B(:,:,:,4*ix-3:4*ix) = A(:,:,:,[C(ix,1),C(ix,1)+1,C(ix,2),C(ix,2)+1]);

All the options are there, you aren't missing any options.
So my question is how to do I use the point curve to invert an image. I am used to the tone curve looking like this.

Nothing has changed, only the interface did. The first icon at the top next to 'Adjust' is the parametric curve. The second icon (white circle) is the point curve. The three colored circles are the individual color channel point curves.

The Clay Mathematics Institute has grouped and classified 7 maths problems as being insurmountable. If someone manages to solve one, they will pocket almost £1 million. Among them, there is the ‘P=NP’ problem. At first glance, this does not ring a bell, yet this equation is considered to be the most ‘solvable’ of the 7.
The person who solves ‘P=NP’ will therefore pocket almost £1 million and revolutionise the way computers operate. But above all, they will have found the key to mining Bitcoin much more quickly. It could therefore be enriched infinitely. The problem is that once revealed, the solution will lead to a decrease in the value of Bitcoin.
This is the problem roughly explained: P = a problem with a fast solving time and NP = a problem with a higher solving time. For a computer, problems are listed between these two categories. The question ‘P=NP’ asks is: do all NP problems have a P solution?
If this problem is solved, finishing sudokus would take a few seconds for a computer. It could also accelerate the mining of bitcoin, hence the fact that it could enrich itself once the problem is solved. Fields such as computer science, engineering, cryptology, mathematics and economics would be disrupted.

Help! I am charting a plot with a lot of points and need to utilize the symbol table to show detections vs non detections, basically open vs closed symbols. I know I can change the symbols in the symbol table, however, every time I open the symbol table it automatically populates the table with random symbols, and not what is currently on the chart. I can go and change every symbol, but this will take weeks with the amount of data I am using. Is there a way to make one symbol and copy and paste to the rest? I know I can use the 'repeat symbols' option, but that won't help me because it copies the results over and over. I need a quick way to make all the symbols the same, but still have the functionality to choose individual symbols to edit them. I am using Grapher 8.8.957 Any help is appreciated. Thanks

Say, there is an increase in demand for dollars (as compared to the other currency, say yen), which will put appreciation pressures on dollar.
Then to counter this appreciation, we need to buy yen. This will increase supply of dollars - hence moderate the appreciation pressures.
Now, because of inflationary pressure, open market operations (OMOs) will be carried out to sell bonds and buy dollars.
But would it not decrease the dollar supply and again appreciate the currency?

|Outline of Final Research Achievements
The objective of the present research is to produce innovative network structures with size effect and nonlocality with keeping the higher specific strength. To realize the structures, the framework structure consisting of beams is the best candidate. The research has been performed from the two kinds of representative sizes; one is the millimeter-sized model. The original framework structure was manufactured by 3D-printer and it is found that the structure shows the predicted negative Poisson ratio. Also, this model has the micrometer-level characteristic length which indicates how large the nonlocality is potentially equipped in the model. The other is micrometer-sized pillar on the surface of materials which was manufactured by focused ion beam. The compressive loading using nanoindentation shows the clear size effect on the yield points and it suggests that the introduction of phase boundary can drastically change the deformability of structures.

Thanks for the specificity of your analysis! Because there is a lot going on in your question, I will go line by line in my response:
Upon reviewing, I can see why E gives an alternative factor, as well as effect without the cause (drop in crime rate without the major policy changes in place yet).
(E) does give an alternate cause, the hiring of more police officers, but this is not an example of "effect without the cause." The stimulus does not say there was a drop in the violent crime rate before the mandatory sentencing law was enacted, and you can't assume there was. The stimulus gives up no information about whether violent crime increased, decreased, or stayed the same in the year before the mandatory sentencing law was enacted.
Your next question refers to the numbers and percents in the stimulus:
However, I am struggling to understand why it is correct that the stim talks about crime rate in % and answer E is comparing something in number (#), new police offers each year. I thought when the stim is talking about % we need another answer that matches with the stim (%). Thats why I got rid of E because of the mismatch.
The flaw in your reasoning is that you are generalizing a little too much about Powerscore's number/percentage tips. The tip is that if you are only told a raw #, you do not know anything about a %, and if you are only told a %, you don't know anything about a number. So you can't simply see a % in the stimulus and a # in the answer choice and eliminate the answer based on that. The other inaccuracy in your statement is that the tip about %s and #s applies when you are talking about the same quantity. For example, knowing the percentage of women in a law school class does not tell you the number of women in the same class. You would have to know the total number of students in the class to determine the % from the # or vice-versa. But in this problem, the % is about violent crimes (crime rate means # of crimes divided by # of people). But the # is the number of police officers hired. It's apples and oranges.
Your last question is about the shift in language from "violent crime rate" to "crime rate":
Also, the conclusion talks about "crime rate" in general whereas, the stim talks about "violent crime rate." So is the conclusion saying because there is an increase in violent crime rate and put in prison there is a decrease in crime rate in general? Or the conclusion is equating crime rate = violent crime rate as being the same thing?
Let's look closely, though. The conclusion says "the
drop in the crime rate," which refers to the drop previously mentioned, the drop in the violent crime rate.
Compare to this example: Yesterday I saw a black cat. The
I am less specific in my second sentence, but it is clear I am referring to the black cat because I didn't mention any others.
I hope this helped. Great questions!

I am fascinated by constraints. As a mathematical optimizer, I know that in some cases, if I impose additional constraints on an optimization problem, it will become much more difficult to solve, but in other cases, it will become considerably easier. Some constraints seem to be structured in such a way that in their presence algorithms have trouble working their way to the best part of the feasible region, whereas other constraints provide the equivalent of handholds and toeholds that form an easily traversed path to an optimal solution. As an artist, I am similarly mindful of constraints. I am inspired by the words of Igor Stravinsky: "The more constraints one imposes, the more one frees one's self of the chains that shackle the spirit.
The Jordan Curve Theorem
15 x 45 cm
The Jordan Curve Theorem states that when a simple closed curve is drawn in the plane, it will cut the plane into two regions: the part lies inside the curve (here, the slightly darker-colored inset piece of wood), and the part that lies outside it (here, the slightly brighter and thicker frame).

Our mathematics curriculum promotes the optimal mathematical development of each student. Through innovative, challenging, and differentiated instruction we seek to develop student’s problem-solving and critical thinking skills and foster an appreciation for the power and beauty of mathematics. Students are encouraged to question, think, reason, compute, and communicate mathematically to solve real-world problems with enthusiasm, confidence, and creativity.
Full year. Students use graphical, symbolic, tabular, and numerical representations as they solve problems involving unknown quantities. Linear equations and linear relationships are examined in great detail, and conceptual understanding is emphasized throughout the course. The graphing calculator is utilized and required. Students are introduced to quadratic equations, factoring, and irrational numbers.
Full year. Prerequisite: Algebra I
In this course, students will study parallelism, congruence, similarity, polygons, circles, area, volume, and transformations. Particular emphasis is placed on inductive and deductive reasoning, logic, and proof. Students will use Geometer’s Sketchpad to explore relationships and formulate conjectures. Concepts of Algebra I are reinforced, including linear equations, graphing, and solving systems. Students are introduced to right triangle trigonometry and counting principles. Algebraic applications of geometry and problem solving are greatly emphasized.
Full year. Prerequisite: Algebra I and qualification
In this course, students will study all of the topics in Geometry but with more theory and in greater depth. A mastery of many algebraic skills will be necessary for students to succeed and meet the demands of this rigorous course. Particular emphasis is placed on inductive and deductive reasoning, logic, proof, and independent problem-solving. Students will use Geometer’s Sketchpad to explore relationships and formulate conjecture.
Full year. Prerequisite: Geometry
Algebra II is an extension of Algebra I with new topics including transformations, higher-order polynomials, exponential, and logarithmic functions. Emphasis is placed on describing relations in multiple ways, developing problem-solving skills, and communicating understanding in verbal and written formats. Students investigate concepts and solve both with and without the use of the graphing calculator.
Honors Algebra II
Full year. Prerequisite: Geometry or Honors Geometry and qualification
Includes much of the same material as Algebra II plus a unit on trigonometry and rational functions, but with more theory and in greater depth. Significant emphasis is placed on communication (verbal, partner and written) as well as on applications and problem-solving.
Honors Algebra II and Precalculus
Full year. Prerequisite: Honors Geometry, and recommendation of department
This course will cover the topics in Honors Algebra II and Honors Precalculus. The pace will be greater and independent thinking and reasoning will be emphasized throughout the course. Students will be expected to investigate concepts and apply their knowledge in a variety of ways. Technology will be used extensively, and students will be required to explore many ideas outside of class time.
Full year. Prerequisite: Algebra II
This alternative to Pre-calculus is a comprehensive review and extension of Algebra II topics with a study of functions, their graphs and applications. Topics covered include matrices, trigonometry, conics, sequences and series, probability and statistics. Much of the course content is similar to that of Pre-calculus, but material is presented at a slower pace. Please note: students in Algebra III/Trigonometry are not eligible to qualify for AP Calculus.
Full year. Prerequisite: Algebra II
This course is a study of functions and graphs including trigonometry, higher order polynomials, exponents, logarithms, analytic geometry, sequences and series, and transformations, also including some principles of probability. Students continuously seek understanding by communicating through use of words, tables, graphs and Algebra. Please note: students who have completed Algebra III/Trigonometry are not eligible to enroll in Pre-calculus. Students should continue to Intro to Calculus & Statistics (below).
Full year. Prerequisite: Algebra II or Honors Algebra II and qualification
This course provides an in-depth examination of polynomial, exponential, logarithmic, power, rational, and trigonometric functions (graphs, equations, and applications) in preparation for AP Calculus. Students communicate their understanding in verbal and written formats. In addition, students thoroughly explore sequences and series, probability, counting methods, and polar graphing, and begin the study of limits, derivatives, and continuity.
Intro to Calculus and Statistics
Full year. Prerequisite: Pre-calculus or Algebra III/Trigonometry
The first semester of this course is devoted to developing an understanding of elementary statistics – graphing and describing data, using data to draw conclusions, and gathering data through surveys and experiments. Students also study normal distributions in depth, including standardizing normal variables and calculating probabilities. In the second semester, students analyze selected topics from Differential Calculus, including limits, continuity, differentiability, and finding and applying derivatives. The final portion of the course focuses on financial mathematics such as investments, exponential models of growth for compound interest, and Business Calculus.

The same happens for me with Mathematica 7.0.1 under Windows 2000: Beep doesn't produce any sound while EmitSound and Play work as expected. Alexey > I'm using a Mathematica 7 for Unix. The command Beep doesn't make any sound. I want to includ a beep after each iteration of a simulation to keep track of the speed and progress.

Multiply the first equation by 2, then add the equations.
We have .
Now, plug p in any equation and find q.
4) Plug x=4.2 and x=4.3 in equation and probably you'll obtain one negative value and one positive value.
5) Let x be the number of middle pieces.
The probability to pick one is .
On the other hand, the same probability is 1-0.008-0.164.
Equalize the two values and solve for x.

A 10.00 gram solid sample consisting of a mixture of sodium chloride and potassium sulfate is dissolved in 100.0 mL of water is combined with another 200.0 mL solution that contains excess aqueous lead(II) nitrate. Upon mixing the two solutions, a solid precipitate forms (it is a mixture of two ionic solids.) It is filtered, dried, and found to have a dry mass of 21.75 grams. Determine the mass percent of sodium chloride in the original solid sample mixture of sodium chloride and potassium sulfate.
Two equations in two unknowns; solve simultaneously.
Let X = mass NaCl
and Y = mass K2SO4
eqn 1 is X + Y = 10.0
eqn 2 is mass PbCl2 (from NaCl) + mass PbSO4(from K2SO4) = 21.75g.
eqn 2 in terms of X and Y is this
(X*MMPbCl2/2*MMNaCl) + (Y*MMPbSO4/MMK2SO4) = 21.75
Solve those two equations for X and Y, then
%NaCl = (Xgrams/10)*100 = ?
Hi, Bob. But how to get (MMPbCl2/2*MMNaCl) and (MMPbSO4/MMK2SO4). Because it is confusing to me. Can you show the step more clearly. Thank you?
I just can do step 1, which is X=10-Y.
But step 2, it is bit confused. I can't get the meaning.
Thank you, I know how to do it.

Hi, Could anybody tell me how much the £2: 2015 First World War Centenary, sure shield of Britain coin is worth? Thanks
I'm wondering if anyone can help me; I have 3 1986 £2 coins. sorry if I waffle on a bit at this point... From what I have read on a website (http://www.coins-of-the-uk.co.uk/dec2p.html) .... "As the edge inscriptions are stamped on the edge of blank coins before striking, they can (and do) appear either way up in theoretically equal quantities". This is where I need help on two of my coins the writing is one way and on the third the writing is the other way upBUT on the third coin not only is the writing the other way up from the first two it reads/spelt differently from the first two... 1st two coins: XIII COMMONWEALTH GAMES SCOTLAND 1986 + The third coin: XIII COMMONWEALTHGAMES SCOTLAND 1986 + Can you help or offer advice in this matter? Kelly

"GMAT math questions", this is the most searchable topic on internet today. Because for each and every student, it is very important to score more marks in GMAT in order to get admission in top business schools for doing MBA. People are buying lots of books and searching math content related to GMAT on internet. On behalf of our website www.onlinemath4all.com, we would like to help the students who would like to score marks in GMAT.
On this webpage, we give GMAT online math practice test which can be taken by any one without any login credentials. At the end of the test, students can check their score instantly and also they can view detailed answer for all the questions. We hope, this online practice test will be a great boost for the students who are looking to score more marks in GMAT.
When students take this online test, they can come to know their level in solving math problems. That is , how far they are able to solve GMAT math questions within the stipulated time. Because, in competitive exams like GMAT, students will have only some seconds to answer each question. When they have math problems, they must be knowing to complete the problems in time.So, before they are going to write competitive exams like GMAT, they need to take some mock tests.
Today, very few web sites are giving online practice test like this. With the aim of helping the students to take mock test, we provide this online practice test. The quality of the questions given in our online practice test are in high standard and practicing these questions will definitely make the students to reach their goals.
Short cut is nothing but the easiest way to solve math problems related to GMAT. In competitive exams, we will have very limited time to solve each problem. Then only we will be able to attend all the questions. If we do problems in competitive exams in perfect manner with all the steps, it will definitely take much time and we may not able to attend the other questions. So we need some other way in which the problems can be solved in a very short time. The way we need to solve the problem quickly is called as shortcut. We have provided the shortcuts and way of solving math problems in detailed answers.
Sample GMAT Math Questions:
1.The monthly incomes of two persons are in the ratio 4:5 and their monthly expenditures are in the ratio 7:9. If each saves $50 per month, find their monthly incomes.
2. Find the average of first 20 natural numbers which are divisible by 7.
3. A person covers a certain distance at a certain speed. If he increases his speed by 33 1/3%, he takes 15 minutes less to cover the same distance. Find the time taken by him initially to cover the distance at the original speed.
4. What is the ratio in which the two types of wheat mixed where the price of the first type is $9.30 per kg and the second type is $10.80 per kg so the mixture is having worth $10 per kg?
5. The average age of three boys is 25 years and their ages are in the proportion 3:5:7. The age of the youngest boy is

How can harmony be explained by mathematics?
More generally, we will speak ofharmony between two notes when the ratio of their frequency is “simple”: a natural integer or a “simple” fraction of natural integers. Definition: When the interval between two sounds is equal to 2, it is called an octave.
With the note departure and his fifthwe now have two grades different whosound good» whole. To build new gradesso just look for the fifth next from note that we just found. These two grades will also sound harmonious.
Music: a story of proportion. A bit of theory… As early as Antiquity, Pythagoras managed to mathematically calculate the sound ratios of the most harmonious musical intervals. The interval between two notes is measured by calculating the frequency ratio between the highest note and the lowest note.
It was composed between 17 and illustrates in a remarkable way how the art of musical writing can be explained by mathematics. The fugue is a musical form where different parts take up the same motif.
Bartok was a composer fascinated by mathematics and by the forms that can be found in nature, such as the spirals of snail shells or the rows of a pine cone.
Whether it makes us soar, vibrate or grumble, music is made up of series of notes or sounds that have mathematics as their foundation. (The length of an object is the distance between its two furthest extremities…)

Actually, the diodes are there to produce a pulsating DC voltage. As you all have been wondering why they are called alternators, it's because they produce an alternating current. The diodes rectify this voltage and thus produce a pulsating DC voltage. The size of the stator windings determine the current the alternator will produce. Thus your higher rated alternators have somewhat larger stator winding. If my college physics serve me, the length of the windings, RPM's and strength of the field determines the voltage and the gauge of the windings and the rating of the diodes are the limiters on the current produced. Also, most quality alternators produce a three phase output, which is to say there are three sets of identical windings in the stator, one end of each is grounded and the other end is attached to a rectifying diode. So the end result is a smooth pulsating DC voltage.

What Is the Formula for Velocity of a Wave?
The formula for the velocity of a wave is v = c/n, with v being velocity of the wave, c being the speed of light, and n is what is going to make the velocity of the wave different. Understand the formula for the velocity of a wave with help from a tutor and teacher in this free video on education and physics.
Promoted By Zergnet
Hi, my name is Samir Malik and I'm a tutor in the Austin area for Middle School and High School students. Today we're going to be discussing the formula for the velocity of a wave. The velocity of a wave, in a given uniform is given by v=c/n. V as a velocity of the wave and c is the speed of light which is pre-determined and n is the refracted index of a medium. So we know that c is the speed of light and it's pre-determined; but n is is what is going to make the velocity of the wave different. For example, the refractive index in water is going to be different than the refractive index in air. So the velocity of wave in water would be less than the velocity of wave in air. So this is the definition of a velocity of a wave and some, and the formula and some examples I have provided you with.

Not all expressions are created equal, but we can still use some algebra to compare unequal numbers, variables, and/or expressions in interesting ways, like inequalities. You've heard of "greater than" and "less than," right? Terrific! First we'll express inequalities on a number line and then write them using information in word problems. Common Core Standard: 6.EE.B.8
We've been taking a lot of equalities. What about when the relationships between numbers need to be expressed as inequalities? For example, less/greater than and/or equal to? How can we represent that idea on a number line?

Authors: JONG HO LEE Title: DOMAIN DECOMPOSITION METHODS FOR REISSNER-MINDLIN PLATES DISCRETIZED WITH THE FALK-TU ELEMENTS Abstract: The Reissner-Mindlin plate theory models a thin plate with thickness t. The condition number of finite element approximations of this model deteriorates badly as the thickness t of the plate converges to 0. In this thesis, we develop an overlapping domain decomposition method for the Reissner-Mindlin plate model discretized by Falk-Tu elements with a convergence rate which does not deteriorate when t converges to 0. We use modern overlapping methods which use the Schur complements to define coarse basis functions and show that the condition number of this overlapping method is bounded by C(1 + H/delta )^3*(1 + log(H/h))^2. Here H is the maximum diameter of the subdomains, delta the size of overlap between subdomains, and h the element size. Numerical examples are provided to confirm the theory. We also modify the overlapping method to develop a BDDC method for the Reissner-Mindlin model. We establish numerically an extension lemma to obtain a constant bound and an edge lemma to obtain a C(1 + log(H/h))^2 bound. Given such bounds, the condition number of this BDDC method is shown to be bounded by C(1 + log(H/h))^2.

When you hear the word "logic," you may think of a number of things. It's the name of a musical artist. It's a certain way of understanding or thinking about something. In the dictionary, the first definition refers to a science which deals with the principles of reasoning. And that's what this quiz is about.
You'll come across logic in mathematics and in philosophy, and it goes all the way back to Aristotle, branching into a number of fields including informal logic, formal logic, symbolic logic and mathematical logic.
But logic puzzles use a part of mathematics involving deduction, and author Charles Lutwidge Dodgson, better known under his pen name and author of Alice in Wonderland, Lewis Carroll, created logic puzzles in his book, The Game of Logic.
Mathematician Raymond Smullyan created some famous logic problems in his books To Mock a Mockingbird and The Lady or the Tiger. He had a series of puzzles dealing with "knights and knaves", where knights always tell the truth and knaves always lie. You'll see variations of these logic problems in this quiz.
Premises like one party always does this, or another party sometimes does that – that's at the heart of figuring out many logic problems. By deducting what can't be the possible answer, you're able to get closer to the right answer.
So are you ready to put on your thinking cap and ace these logic problems? Show off your smarty pants and take this quiz! Good luck and have fun!

Classifying fluid types requires understanding the Newtonian Vs. non-Newtonian liquid concept. For example, water, alcohol, honey, gasoline, transmission fluid, brake fluid, etc., are various fluids that fall within these two categories.
However, ascertaining the major factor that defines a Newtonian and non-Newtonian fluid will help classify these fluids properly. The underlying factor will also help differentiate fluids that are classified as Newtonian and those considered to be non-Newtonian.
Let’s find out what Newtonian and non-Newtonian fluids are and why they are both different. Carefully go through the subsequent sections with rapt attention.
What is Newtonian Fluid?
Newtonian fluids are liquids or fluids with a constant viscosity that is not subject to change irrespective of the amount of pressure exerted on the fluid. They are called Newtonian fluids for a reason, and that is because the fluids align with Newton’s viscosity law.
The Newtonian fluid’s viscous stress that arises from the flow of the fluid closely correlates with its local strain rate. The fluid is characterized by a zero shear rate in correlation with zero shear stress. The shear rate is of course directly proportional to the fluid’s shear stress.
Newtonian fluid formula is expressed as τ=μ·∂u/∂y. In this formula, τ stands for the fluid’s shear stress, ∂u/∂y expresses the fluid’s rate of strain, and μ is the constant of proportionality, which is a fluid or liquid transport property commonly referred to as “dynamic viscosity.”
What is Non-Newtonian Fluid?
Non-Newtonian fluids are liquids or fluids with a variable viscosity that changes once enough pressure is applied to the fluid. This fluid type is the complete opposite of Newtonian fluids. They don’t compress regardless of the amount of pressure.
Some of the major categories of non-Newtonian fluids include; dilatants and pseudoplastic. Dilatants are non-Newtonian fluids that get thicker once enough pressure is applied. Conversely, pseudoplastic are non-Newtonian fluids that get thinner under a similar condition.
Although their viscosity is variable; however, while one gets thicker under pressure, the other gets thinner with the same pressure.
Furthermore, these non-Newtonian fluid categories can be broken down as follows – rheopectic and thixotropic. Rheopectic fluids can be likened to dilatants due to the fact that they also get thicker once pressure or force is applied.
On the other hand, thixotropic fluids get thinner like pseudoplastic under the same situation of applied force or pressure. However, there’s a slight difference between the first categorization and the second.
While the viscosity level of both dilatants and pseudoplastic fluids change immediately at a particular amount of pressure, rheopectic and thixotropic fluids’ viscosity levels change gradually as the amount of pressure or force increases over time.
What is the difference between Newtonian and non-Newtonian?
Understanding Newton’s law of viscosity is necessary for differentiating Newtonian fluids from non-Newtonian fluids. The law states that “shear stress is directly proportional to the velocity gradient.”
Therefore, Newtonian fluids are those that comply with Newton’s viscosity law due to the fact that their viscosity remains constant regardless of the amount of pressure or force exerted on them.
On the contrary, non-Newtonian fluids are those that do not comply with Newton’s viscosity law, being that their viscosity is altered by the amount of force or pressure exerted on them. Non-Newtonian fluids come in different categories, and they are classified under different factors.
Newtonian vs. non-Newtonian fluid examples
Newtonian vs. non-Newtonian fluid examples are around us in our environment. People interact with these types of fluids daily without recognizing the categories under which they fall. Some common examples of Newtonian fluids are;
- Motor oil
- Kerosene, etc.
While the above are classified as Newtonian fluids because they comply with Newton’s viscosity law, the following are classified as types of non-Newtonian fluids because they operate in the opposite dimension of Newtonian fluids;
- Corn starch
- Melted butter
- Starch suspension
- Honey, etc.
Newtonian vs. non-newtonian fluids definition
Newtonian fluid is defined as a fluid that obeys the viscosity law as propounded by Sir Isaac Newton (popularly referred to as “Newton’s law of viscosity”). The fluids’ viscosity remains unchanged irrespective of pressure or force.
On the flip side, non-Newtonian fluids can be defined as fluids with an opposite behavior to Newtonian fluids; hence, their viscosity changes based on the force or pressure applied to them. So, they basically do not obey Sir Isaac Newton’s viscosity law.
Newtonian vs. non-newtonian viscosity
Newtonian fluids and non-Newtonian fluids have two different viscosity operations. This is the major factor that differentiates the two categories of fluids.
The viscosity of a Newtonian fluid is completely independent of the fluid’s shear rate. Therefore, while the pressure or force applied to the fluid rises or declines, the viscosity remains constant.
Meanwhile, the viscosity of a non-Newtonian fluid is dependent on the fluid’s shear rate. Hence, applying force or pressure to Newtonian fluids will alter the viscosity because of the variable nature.
Newtonian flow vs. non-Newtonian flow
Based on the definitions of the categories of fluids, Newtonian flow differs from the non-Newtonian flow. The viscous stress that arises from the Newtonian flow is always linearly correlated to its local strain rate.
Meanwhile, in the case of non-Newtonian fluids, the shear stress and the shear rate are not linearly correlated; they are completely different. If you’re asking, “Is ketchup a non-newtonian fluid?” Yes, it is a non-Newtonian fluid because it becomes runnier once you shake it up (applied force).
Shaking the ketchup will help to re-homogenize its particles evenly such that the solid part can mix properly with the watery part.
Q: How do you determine if fluid is Newtonian or non-Newtonian?
Determining whether a particular fluid is Newtonian or non-Newtonian is based on Newton’s law of viscosity. Newtonian fluids align with Newton’s law of viscosity; hence, they have a constant viscosity.
On the other hand, non-Newtonian fluids do not align with Newton’s law of viscosity; hence, their viscosity is variable. Therefore, while Newtonian fluids’ viscosity remains unchanged irrespective of pressure, non-Newtonian fluids’ viscosity changes in a moment in the face of enough pressure.
Q: Is motor oil a Newtonian fluid?
Not really! Motor oil is a non-Newtonian type of fluid. This is due to its varying viscosity under different temperatures or levels of pressure. It is difficult to describe motor oil using a particular viscosity number.
For instance, a particular motor oil viscosity level can change rapidly with a slight temperature increment of 5 degrees Celsius. Even the crude oil from which most motor oils are manufactured is non-Newtonian. Other non-Newtonian fluids include water, glycerol, alcohol, etc.
Q: Is brake fluid Newtonian or non-Newtonian fluid?
Brake fluid is a Newtonian fluid. The fluid has a constant viscosity which is not altered by a leap or decrease in temperature. However, this quality is very important for brake fluids because of the role of a constant viscosity irrespective of temperature change.
Constant viscosity ensures that the brake fluid remains active when you engage your vehicle’s brake, even under extremely cold temperatures. Brake fluid viscosity is measured at two different points: 100 degrees Celsius and –40 degrees Celsius, respectively.
Q: Is transmission fluid Newtonian or non-Newtonian fluid?
Transmission fluid is a non-Newtonian fluid. Automatic Transmission Fluids (ATFs) have polymeric viscosity modifiers, which makes them manifest the characters of non-Newtonian fluids. Their viscosity varies as temperature or pressure level changes.
For instance, a rise in temperature will result in lower viscosity in transmission fluid and vice versa. This is the basic reason why transmission fluid is a non-Newtonian fluid. You may want to perform an experiment to verify this fact about transmission fluids.
Q: Is antifreeze Newtonian or non Newtonian fluid?
Antifreeze is a non-Newtonian fluid. Antifreeze additives increase the boiling point of a particular water-based liquid. It also has the capacity to lower the freezing point of such liquid.
The viscosity of an antifreeze fluid is subject to change when pressure or force is applied to it.
Therefore, it is classified as a non-Newtonian fluid because the fluid does not obey the viscosity law as propounded by Sir Isaac Newton.
Distinguishing Newtonian vs. non-Newtonian is pretty straightforward. The major factor is the behavior of the viscosity of the fluid once force or pressure is applied. This article has unveiled the various categories of Newtonian and non-Newtonian fluids for your awareness.
So, drawing a line between different types of fluids, especially fluids that are closely related, will be easy due to their behavior as either Newtonian or non-Newtonian fluids.
If you know someone who’s confused about the two broad categories of fluid according to their behavior, kindly refer them to this article.

$100,000 will be subject to double taxation.
Penguin could have avoided paying corporate tax if, instead of paying a dividend, it had paid Bob and Leo a salary of $50,000 each (assuming a $50,000 salary for each is reasonable).
A preferential tax rate will apply to the dividend income of both Bob and Leo.
If Penguin had paid Bob and Leo a salary of $50,000 each, Bob would have paid less Federal income tax on his salary than Leo would have paid on his salary.
None of the above.

triangle T2 which has its vertices at the points of contact between
the triangle T1 and its incircle. Now keep repeating this process
starting with T2 to form a sequence of nested triangles and
circles. What happens to the triangles? You may like to investigate
this interactively on the computer or by drawing with ruler and
compasses. If the angles in the first triangle are a, b and c prove
that the angles in the second triangle are given (in degrees) by
f(x) = (90 - x/2) where x takes the values a, b and c. Choose some
triangles, investigate this iteration numerically and try to give
reasons for what happens. Investigate what happens if you reverse
this process (triangle to circumcircle to triangle...)
M is any point on the line AB. Squares of side length AM and MB are
constructed and their circumcircles intersect at P (and M). Prove
that the lines AD and BE produced pass through P.

Hi. You might start with the Min() function.
Example, Min( 5; 3; 9; 7; 8 ) — yields 3
You might use it like this: Min( calcfield1; calcfield2; calcfield3 )
I'd suggest using the Let () function. It allows you to use the results of each test in later test.
Let ( [
result1 = Case ( A < B ; A ; B ) ;
result2 = Case ( C < result1 ; C ; result1 ) ] ;
Assuming this is being done in the Calculation Dialog, you can use the Min function to determine the minimum value. Example:
Min ( Subtotal ; DiscountTotal ; StandardAmt )
will return the smallest value among the three options. Note that this will work if the three fields are on the same record. (This would include calculation fields.)
Thanks all. I'll be madly reading up on these sections of the book tonight... to see if I can figure out how to accurately apply these suggestions to my d.base.
Keep 'em coming!
And thanks for the direction. I felt like I was swimming in mud here.

Using AutoFill in Excel, you can quickly fill the same sequence or the sequence with a tolerance of 1 directly. But what if the tolerance of arithmetic sequence you need to fill is not 1? In fact, Excel enables you to customize the tolerance and fill the arithmetic sequence automatically. Let’s see how to do it.
1. Open an Excel sheet, enter the initial value in any of the cells.
2. Select all the cells you want to fill in the arithmetic sequence.
3. Find Fill button in Home tab. Choose Series… in the drop-down list.
4. Check Linear in Type and enter the tolerance beside Step value. Then hit OK to implement it.
5. Now the arithmetic sequence is filled automatically.
6. You can also enter a negative nubmer in Step value.
7. Thus you can fill a decreasing arithmetic sequence quickly.

What is the Bohr's atomic model?
Bohr used Balmer's work on the line spectrum of Hydrogen to prove the quantisation of electron energy levels in the atom. This complemented Planck's work which had given rise to quantum theory. So it was very significant.
There is a flaw in the model, that is, Bohr believed that electrons orbited the nucleus in much the same way as planets orbit the Sun. That is incorrect. Schrödinger proposed a model nearer to how we understand atomic structure which is based on wave behaviour. In the model electrons exist as a type of standing wave within the confinement of the nucleus' influence. I don't have a very strong grasp of this model so that's as far as I can explain it.
