Q. Patrick estimated he would need 4545 minutes to get ready for the first day of school, but he only needed 4040 minutes. What is the percent error for his estimate? If necessary, round your answer to the nearest tenth of a percent.\newline____%\%
  1. Calculate Difference: Calculate the difference between the estimated time and the actual time needed.\newlineDifference = Estimated Time - Actual Time\newlineDifference = 4545 minutes - 4040 minutes = 55 minutes
  2. Calculate Percent Error: Calculate the percent error using the formula: Percent Error = (EstimatedActual/Actual)×100%(|\text{Estimated} - \text{Actual}| / \text{Actual}) \times 100\%.
    Percent Error = (5/40)×100%(5 / 40) \times 100\%
    Percent Error = 0.125×100%=12.5%0.125 \times 100\% = 12.5\%
