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.(1 point)
Answer CORRECTLY
To calculate the percent error, we can use the formula:
Percent Error = (|Observed Value - Predicted Value| / Predicted Value) * 100
In this case:
Observed Value = 53 minutes
Predicted Value = 60 minutes
Plugging the values into the formula, we get:
Percent Error = (|53 - 60| / 60) * 100
= (|-7| / 60) * 100
= (7 / 60) * 100
= 11.7
Therefore, the percent error is 11.7%, rounded to the nearest tenth.
