Question

The forecast predicted there would be 5 inches of snow, but we actually received 4 inches of snow. What is the percent error?

Answer 1

The percent error in the snowfall prediction is calculated as the absolute difference between actual and predicted values, divided by the predicted value, multiplied by 100%. In this scenario, the percent error is found to be 20%.

Step-by-step explanation:

The question you asked about the percent error in a snowfall prediction is a common exercise in Mathematics, specifically in the calculation of errors. To find the percent error, you need to compare the predicted amount of snow against the actual amount received. The formula for percent error is:

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

In this case, the predicted value was 5 inches, and the actual value was 4 inches. Using the formula, we can calculate:

Percent Error = (|4 - 5| / 5) x 100% = (1 / 5) x 100% = 20%

So, the percent error in the snowfall prediction was 20%.
