Julian and Brittany mailed 275 wedding invitations to family and friends and predicted that they would all attend. Only 265 out of 275 people committed to attending the wedding. Calculate the percent error in their prediction. Round your answer to the nearest hundredth percent.(1 point)

The percent error can be calculated using the formula:
Percent Error = (|Predicted Value - Actual Value| / Actual Value) * 100
In this case, the predicted value is 275 and the actual value is 265.
Percent Error = (|275 - 265| / 265) * 100
Percent Error = (10 / 265) * 100
Percent Error = 3.77 (rounded to the nearest hundredth percent)
Therefore, the percent error in their prediction is 3.77%.
