Question

Debbie measures the length of the pencil to be 25 centimeters. The actual length of the pencil is 23 centimeters. What is the percent error for Debbie’s measurement?

Answer 1

Debbie's measurement has a percent error of 8.7%. To find the percent error, subtract the actual value from the measured value, take the absolute value, divide by the actual value, and multiply by 100%.

Step-by-step explanation:

To find the percent error, we need to compare Debbie's measurement to the actual measurement.

The formula for percent error is:

Percent Error = (|Actual Value - Measured Value| / Actual Value) x 100%

In this case, the actual length of the pencil is 23 centimeters and Debbie's measurement is 25 centimeters. Plugging these values into the formula, we get:

Percent Error = (|23 - 25| / 23) x 100% = 8.7%
