Question

Adrian measured a line to be 13.8 inches long. If the actual length of the line is 13.1

inches, then what was the percent error of the measurement, to the nearest tenth of a
percent?

Answer 1

5.34%.

Explanation:

Given that,

Measured length of a line = 13.8 inches

Actual length of the line = 13.1 inches

We need to find the percent error of the measurement. We can find it as follows :

`\%=(|measured-actual|)/(actual)* 100\\\\\%=(13.8-13.1)/(13.1)* 100\\\\\%=5.34\%`

So, the required percentage is equal to 5.34%.
