Killian and Britney mail 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 production round your answer to the nearest hundred percent
A. 3.77%.
B.-4.00%.
C. 3.63%.
D. 0.038%.
To calculate the percent error, we need to find the difference between the predicted attendance and the actual attendance, and then divide that difference by the predicted attendance. Finally, we multiply by 100 to get the percentage.
Predicted attendance: 265
Actual attendance: 275
Difference: 275 - 265 = 10
Percent error = (Difference / Predicted attendance) * 100 = (10 / 265) * 100 ≈ 3.77%
Therefore, the correct answer is A. 3.77%.
