Question

The actual length of a machine is 12.25 cm. The measured length is 12.2 cm.

Find the absolute error.

Answer 1

Answer:First, calculate the difference between two length. The difference is the error of measurement.

the difference = actual - measured

the difference = 12.25 - 12.2

the difference = 0.05

Second, calculate the percent error

To calculate the percentage, we will use the following method

percent = the error measurement/actual measurement × percentage actual measurement (100%)

Third, input the number

percent = 0.05/12.25 × 100%

percent = 1/245 × 100%

percent = (100/245) %

percent = 0.408 %

percent = 0.4 %

Percentage of error is 0.4%
