Question

When Adele arrived at her dentist appointment, the receptionist told her the wait would be about 20 minutes. Adele actually waited only 16 minutes. What is the percent error for the receptionist's estimate

Answer 1

To find the percent error, compare the estimate to the actual value using the formula: Percent Error = [(|Estimated Value - Actual Value|) / Actual Value] * 100%. In this case, the percent error is 25%.

Step-by-step explanation:

To find the percent error for the receptionist's estimate, you need to compare the estimate to the actual value. In this case, the receptionist estimated a wait time of 20 minutes, but Adele only waited 16 minutes. The percent error can be found using the formula: Percent Error = [(|Estimated Value - Actual Value|) / Actual Value] * 100%.

Substituting the values into the formula, we get: Percent Error = [(|20 - 16|) / 16] * 100%. Simplifying, we have: Percent Error = (4 / 16) * 100%.

Dividing 4 by 16 gives us 0.25, and multiplying by 100% gives us 25%. Therefore, the percent error for the receptionist's estimate is 25%.
