Q. The meteorologist at Channel 88 News predicted that a snowstorm would drop 77 inches of snow. After the storm, she reported that the actual snowfall was 44 inches. What is the percent error for the meteorologist's prediction?\newlineIf necessary, round your answer to the nearest tenth of a percent.\newline____%\%
  1. Calculate Difference: Calculate the difference between predicted and actual snowfall.\newlineDifference = Predicted snowfall - Actual snowfall = 77 inches - 44 inches = 33 inches.
  2. Use Percent Error Formula: Use the percent error formula: Percent Error = (Difference/Actual)×100(|\text{Difference}| / \text{Actual}) \times 100.\newlinePercent Error = (3/4)×100=75%(3 / 4) \times 100 = 75\%.
