Julian and Britney mailed 275 wedding invitations to family and friends in predicted that they would all attend only 265 out of 275 people committed to attending the wedding calculate the percent error of their prediction round your answer to the nearest hundred percent
To calculate the percent error, we need to find the difference between the predicted number of attendees and the actual number of attendees, divide that by the predicted number of attendees, and then multiply by 100 to get a percentage.
The predicted number of attendees is 275.
The actual number of attendees is 265.
The difference is: 275 - 265 = 10
To get the percent error: (10 / 275) * 100 = 3.64%
Rounding to the nearest hundred percent, the percent error of their prediction is 4%.
