Question

ray predicted that he would score 16 points during the basketball game. he only scored 12 points. what is the percent error?

Explanation:

Step1: Calculate the absolute error

The formula for absolute error is \(| \text{Predicted Value}-\text{Actual Value}|\).
Here, predicted value \(= 16\), actual value \(= 12\).
\(|16 - 12|=4\)

Step2: Calculate the percent error

The formula for percent error is \(\frac{\text{Absolute Error}}{\text{Actual Value}}\times100\%\)
Substitute absolute error \( = 4\) and actual value \(=12\) into the formula:
\(\frac{4}{12}\times 100\%=\frac{1}{3}\times100\%\approx 33.3\%\)

Answer:

\(33.3\%\)
