Mark and Matthew signed up to walk a 5K walk run race they predict it will take them 60 minutes to complete the race. Mark and Matthew finish the race in 53 minutes. What is the percent error round to the nearest 10th
To calculate the percent error, we use the formula:
Percent Error = (|Predicted Value - Actual Value| / Actual Value) * 100
In this case, the predicted value is 60 minutes and the actual value is 53 minutes.
Percent Error = (|60 - 53| / 53) * 100
Percent Error = (7 / 53) * 100
Percent Error ≈ 13.2%
Rounding to the nearest 10th, the percent error is approximately 13.2%.
To find the percent error, we need to calculate the difference between the predicted time and the actual time and express it as a percentage of the predicted time.
1. Calculate the difference between the predicted time and the actual time:
Difference = Predicted Time - Actual Time
Difference = 60 minutes - 53 minutes
Difference = 7 minutes
2. Calculate the percent error:
Percent Error = (Difference / Predicted Time) * 100
Percent Error = (7 minutes / 60 minutes) * 100
Percent Error = 11.67%
Rounded to the nearest tenth, the percent error is approximately 11.7%.
To calculate the percent error, we need to find the absolute difference between the predicted time and the actual time, and then divide it by the predicted time. Finally, we need to multiply by 100 to get the percentage.
1. Find the absolute difference: 60 minutes - 53 minutes = 7 minutes.
2. Divide the absolute difference by the predicted time: 7 minutes / 60 minutes = 0.1167.
3. Multiply by 100 to get the percentage: 0.1167 * 100 = 11.67%.
Rounding to the nearest tenth, the percent error is 11.7%.
