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.

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. (If the N + 1 digit is 5 followed by nothing or by zeros only, use the 'round half to even' tiebreaking rule). --- An odometer with a precision of +/- 400 meters measures a distance of 33900 meters and a clickwheel with a precision of +/- 0.2 meters measures a distance between two different points as 395.3 meters. Using a calculator, you multiply the first number by the second number and get the output. If we round this output appropriately with respect to the level of precision, what is the answer? A. 13400670.000 meters^2 B. 13400000 meters^2 C. 13400600 meters^2 Answer:

You divide the first value by the second value with a calculator and get the solution. If we express this solution to the right level of precision, what is the result? A. 6837.50 seconds/gram B. 7000 seconds/gram C. 6837.5 seconds/gram Answer:

You multiply the former value by the latter with a calculator and get the solution. If we round this solution appropriately with respect to the number of significant figures, what is the answer? A. 865.900 meters^2 B. 860 meters^2 C. 866 meters^2 Answer:

After multiplying the numbers your calculator gives the output. Using the appropriate number of significant figures, what is the answer? A. 5000000 gram-meters B. 4900000.0 gram-meters C. 4900000 gram-meters Answer:
