Mark and Matthew signed up to walk in a 5K walk/run race. They predict it will take them 60 minutes to complete the race. Mark and Matthew finished the race in 53 minutes. What is the percent error? Round to the nearest tenth.
can you help, i'm confused
To find the percent error, we need to compare the predicted time to the actual time and calculate the difference as a percentage of the predicted time.
The predicted time is 60 minutes, and the actual time is 53 minutes.
The difference between the predicted and actual time is 60 - 53 = 7 minutes.
Now, we can calculate the percent error using the formula:
Percent Error = (|Actual Value - Predicted Value| / Predicted Value) * 100%
Plugging in the values:
Percent Error = (|53 - 60| / 60) * 100%
Percent Error = (7 / 60) * 100%
Percent Error = 11.67%
Rounded to the nearest tenth, the percent error is 11.7%.
are u sure for some reesan I thought it was 7 percent
I apologize for the confusion. Let's double-check the calculations.
The predicted time is 60 minutes, and the actual time is 53 minutes.
The difference between the predicted and actual time is 60 - 53 = 7 minutes.
Now, we can calculate the percent error using the formula:
Percent Error = (|Actual Value - Predicted Value| / Predicted Value) * 100%
Plugging in the values:
Percent Error = (|53 - 60| / 60) * 100%
Percent Error = (7 / 60) * 100%
Percent Error = 0.1167 * 100%
Percent Error = 11.67%
Rounded to the nearest tenth, the percent error is indeed 11.7%. I apologize for the confusion in my previous response.
