NOTE: To propagate uncertainty when multiplying or dividing two measurements, count the number of significant figures in each. Your result should be reported to the number of significant figures in the measurement having the lesser number of significant figures. Note that 'significant figures' are different than 'decimal places'; see rules at https://en.wikipedia.org/w/index.php?title=Significant_figures&oldid=1114415444#Identifying_significant_figures . Rounding a number to N significant figures is similar to rounding to N digits after the decimal point, except that we start counting from the beginning of the number. For example, 71.25150 rounded to three significant figures is 71.3, to four is 71.25, and to one is 70.

Rounding a number to N significant figures is similar to rounding to N digits after the decimal point, except that we start counting from the beginning of the number. For example, 71.25150 rounded to three significant figures is 71.3, to four is 71.25, and to one is 70. (If the N + 1 digit is 5 followed by nothing or by zeros only, use the 'round half to even' tiebreaking rule). --- A cathetometer with a precision of +/- 0.0002 meters takes a measurement of 0.0033 meters, and a coincidence telemeter with a precision of +/- 100 meters reads 749100 meters when measuring a distance between two different points. After multiplying the values your calculator app gets the output. Using the right number of significant figures, what is the result? A. 2400 meters^2 B. 2500 meters^2 C. 2472.03 meters^2 Answer:

NOTE: To propagate uncertainty when multiplying or dividing two measurements, count the number of significant figures in each. Your result should be reported to the number of significant figures in the measurement having the lesser number of significant figures.

You divide the first value by the second value with a calculator and get the solution. When this solution is written to the appropriate level of precision, what do we get? A. 75745.257 grams/meter B. 75700 grams/meter C. 75740 grams/meter Answer:

You multiply the first value by the second value with a computer and get the solution. How would this answer look if we expressed it with the right level of precision? A. 10 meters^2 B. 16.8 meters^2 C. 20 meters^2 Answer:

Using a calculator, you divide the first value by the second value and get the output. How can we express this output to the correct level of precision? A. 2555.56 grams/meter B. 2500 grams/meter C. 2600 grams/meter Answer:
