Q. When Quincy saw the length of the line at the department store's cash register, he predicted he'd have to wait 15 minutes. He actually waited only 10 minutes. What is the percent error for Quincy's prediction?If necessary, round your answer to the nearest tenth of a percent.____%
Calculate Difference: Calculate the difference between the predicted time and the actual waiting time.Difference = Predicted time - Actual timeDifference = 15 minutes - 10 minutes = 5 minutes
Calculate Percent Error: Calculate the percent error using the formula: Percent Error = (∣Predicted−Actual∣/Actual)×100%.Percent Error = (5/10)×100%Percent Error = 0.5×100%=50%
