Question

Angel measured a line to be 4 inches long. If the actual length of the line is 5.2 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answer 1

the percent error of the measurement is 23.1%.

Explanation:

To calculate the percent error, we can use the following formula:

percent error = |(measured value - actual value) / actual value| * 100%

In this case, the measured value is 4 inches and the actual value is 5.2 inches. Plugging these values into the formula, we get:

percent error = |(4 inches - 5.2 inches) / 5.2 inches| * 100% = 23.0769%

Rounding this to the nearest tenth of a percent, we get 23.1%.

Therefore, the percent error of the measurement is 23.1%.
