Shaun Woodward · Answer 1

7.89 7.91

Explanation:

The ranges of measurement lie between 7.92-0.05 and 7.92+0.05

7.87g and 7.97g

Thomas Waller · Answer 2

Answer: 7.89g, 7.91g and 7.97 g

Explanation:

Precision has to do with the maximum value of allowance that can be accepted when added to the original measurement of an object.

Since the accepted value of measurement is 7.92g with precision of ± 0.05 g

The accepted range will be either 7.92+0.5 and 7.92 - 0.5 to give 7.97g and 7.87g

This two values are the maximum and minimum value that can be accepted respectively. Any value that falls in between can also be accepted.

7.87g<=x<=7.97 (acceptable range)

Therefore only 7.89g, 7.91g and 7.97g falls within this range.
