Question

question 1 of 10
a scale measures weight to the nearest 0.1 pounds. which is the most appropriate way to report weight using this scale?
a. 152.2 pounds
b. 152 pounds
c. 200 pounds
d. 152.127 pounds

Explanation:

Step1: Understand the scale's precision

The scale measures to the nearest 0.1 pounds, so the reported weight should have one decimal place (tenths place) to reflect this precision.

Step2: Analyze each option

• Option A: 152.2 pounds has one decimal place, matching the scale's precision (nearest 0.1 pounds).
• Option B: 152 pounds has no decimal places, which is less precise than the scale's capability.
• Option C: 200 pounds is a whole number, also less precise than needed.
• Option D: 152.127 pounds has three decimal places, which is more precise than the scale (which only measures to the nearest 0.1, so one decimal place). The scale can't measure to the thousandths place, so this is inappropriate.

Answer:

A. 152.2 pounds
