Question

Audrey has been practicing her basketball free throws. she predicts to her friends that she will make 15 free throws before she misses one, but she actually makes 20 free throws before missing. what is the percent error for audrey's prediction?

If necessary, round your answer to the nearest tenth of a percent.
__ %

Answer 1

To find the percent error, we can calculate the difference between Audrey's predicted and actual values, and express it as a percentage.Audrey's free throw prediction had a 25% error, deviating from the actual 20 free throws made.

Step-by-step explanation:

To find the percent error for Audrey's prediction, we need to calculate the difference between her predicted number of free throws and the actual number of free throws she made. The percent error can be calculated using the formula:

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

Given that Audrey predicted to make 15 free throws before missing, but actually made 20 free throws before missing, we can substitute these values into the formula:

Percent Error = (|15 - 20| / 20) x 100% = 25%

Therefore, the percent error for Audrey's prediction is 25%.

To assess the accuracy of Audrey's prediction regarding free throws, the percent error is computed by comparing her predicted value of 15 with the actual value of 20. Applying the percent error formula, we find a deviation of 25%. This indicates that Audrey's prediction deviated by 25% from the actual number of free throws made, highlighting the variance in her estimation.
