Precision in Measurement

Question 9 • AZ-Common Core Algebra II A

A scale measured a 4.5-pound brick as weighing 5.3 pounds. Which measurement is more accurate but less precise than 5.3 pounds?

Answer
A
4.98 pounds
B
5 pounds
C
5.52 pounds
D
6 pounds

Explanation

The brick’s actual weight is 4.5 pounds, so a more accurate measurement must be closer to 4.5 than 5.3 is. The measurement 5 pounds is only 0.5 pound away, compared with 0.8 pound for 5.3. It is less precise because it is given to the nearest whole pound rather than the nearest tenth.
