Question

The meteorologist at Channel 8 News predicted that a snowstorm would drop 7 inches of

snow. After the storm, she reported that the actual snowfall was 4 inches. What is the
percent error for the meteorologist's prediction?
If necessary, round your answer to the nearest tenth of a percent.
%

Answer 1

To find the percent error in the meteorologist's prediction, subtract the actual snowfall from the predicted snowfall, divide the absolute error by the predicted snowfall, and multiply by 100.

Step-by-step explanation:

To find the percent error in the meteorologist's prediction, we first need to calculate the absolute error. The absolute error is the difference between the predicted snowfall and the actual snowfall, which is 7 - 4 = 3 inches.

Next, we'll calculate the percent error by dividing the absolute error by the predicted value and multiplying by 100. So, the percent error is (3/7) * 100 = 42.9%.

Therefore, the percent error for the meteorologist's prediction is approximately 42.9%.
