Answer :
Answer:
The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
