Question

Allison measured a line to be 5.4 inches long. If the actual length of the line is 5.5 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 1.8%.

Step-by-step explanation:

To calculate the percent error, we need to find the absolute difference between the measured value and the actual value, divide it by the actual value, and then multiply by 100 to get a percentage.

In this case, the measured value is 5.4 inches and the actual value is 5.5 inches. So, the absolute difference is |5.4 - 5.5| = 0.1 inches.

Now we can calculate the percent error: (0.1 / 5.5) * 100 = 1.81818181...% = 1.8% (rounded to the nearest tenth of a percent).
