Question

Ms. Kuhn predicts that 280 people will attend the school concert. There was an actual total of 250 people who attended the school concert. What is the percent error?

Answer 1

To calculate the percent error for the school concert attendance, subtract the actual attendance from the predicted attendance, divide the result by the actual attendance, and multiply by 100. The percent error in Ms. Kuhn's prediction is 12%.

Step-by-step explanation:

The question involves calculating the percent error between the predicted and actual attendance of a school concert. The formula for percent error is: (|predicted value - actual value| / actual value) × 100%.

In this case, Ms. Kuhn predicted 280 people would attend, but 250 people actually attended. To find the percent error, we do the following:

Subtract the actual attendance (250) from the predicted attendance (280): 280 - 250 = 30.

Divide the difference by the actual attendance: 30 / 250 = 0.12.

Multiply by 100 to convert to a percentage: 0.12 × 100 = 12%.

Therefore, the percent error in Ms. Kuhn's prediction is 12%.
