------------------------------------------------ Lou predicts tomorrow's temperature to be 72 degrees, but it only reaches 66 degrees. What was his percent error?

A. 6%
B. 72%
C. 66%
D. 0.09%

The percent error of Lou's temperature prediction is 9.09%, calculated using the formula (| Estimated value - True value | / True value) x 100. Unfortunately, none of the multiple choice options matches this correct answer.

Explanation:

The question aims to find out the percent error of Lou's temperature prediction. Percent error is calculated using the formula:

(| Estimated value - True value | / True value) x 100

In our case:

Estimated value is 72 degrees (Lou's prediction), and the True value is 66 degrees (the actual temperature).

Performing the calculations, we obtain:

((|72-66|) / 66) x 100 = (6 / 66) x 100 = 0.0909 x 100 = 9.09%

Sadly, none of the multiple choices given (6%, 72%, 66%, 0.09%) match the correct answer of 9.09%.
