i-Ready Percent Change - Quiz - Level G ) A meteorologist forecasted that Monday's high temperature would be 76°F. On Monday, the temperature reached 80°F. 1) What is the percent error in the meteorologist's forecast for Monday? error: % X 7 8 9 4 5 6 1 2 3 다. m

The percent error is calculated by the formula Absolute Value of (Error - Actual / Actual then times 100).

In this case the Error value was 76, and the Actual was 80.

So, set up the expression

I(76 - 80)/80 x 100I

I-4/80 x 100I

I-400/80I

I-5I

5

The percent error was 5 percent, since that was how much her estimation differed from the actual amount.

You got it right!
