Question

Logan measured a line to be 7.4 inches long. If the actual length of the line is 7.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?​

Answer 1

I think it’s 3.8% i’m not sure tho

Answer 2

3.9%

Explanation:

Percentage error

`= (7.7 - 7.4)/(7.7) * 100 \\ \\ = (0.3)/(7.7) * 100 \\ \\ = (300)/(77) \\ \\ = 3.8961039 \\ \\ = 3.9 \%`
