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 their percent air and prediction around your answer to the nearest hundred percent
To calculate the percent error in Julian and Brittany's prediction, we need to compare the number of people they predicted would attend (265) to the actual number of people who committed to attending (275).
Step 1: Find the difference between the predicted number and the actual number:
Difference = Actual number - Predicted number
Difference = 275 - 265
Difference = 10
Step 2: Calculate the percent error:
Percent Error = (Difference / Actual number) * 100
Percent Error = (10 / 275) * 100
Percent Error ≈ 3.64%
Rounding to the nearest hundred percent, the percent error in Julian and Brittany's prediction would be 4%.
