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. Galculate the percent error in their prediction. Round your answer to the nearest hundredth percent. (1 point)
To calculate the percent error in their prediction, we need to find the difference between the predicted number of attendees (275) and the actual number of attendees (265), divide that by the predicted number of attendees, and then multiply by 100 to convert to a percentage.
Percent Error = (|Predicted - Actual| / Predicted) * 100
Percent Error = (|275 - 265| / 275) * 100
Percent Error = (10 / 275) * 100
Percent Error = 0.03636363636 * 100
Percent Error ≈ 3.64%
Therefore, the percent error in their prediction is approximately 3.64%.
To calculate the percent error in their prediction, we need to compute the difference between the predicted number of attendees and the actual number of attendees, and then divide it by the predicted number of attendees. Finally, we multiply the result by 100 to get the percentage.
The predicted number of attendees is 275, and the actual number of attendees is 265.
Difference = Predicted number of attendees - Actual number of attendees
Difference = 275 - 265
Difference = 10
Percent Error = (Difference / Predicted number of attendees) * 100
Percent Error = (10 / 275) * 100
Calculating this expression, we find:
Percent Error = 0.0363 * 100
Percent Error ≈ 3.63%
Therefore, the percent error in their prediction is approximately 3.63%.
To calculate the percent error, we need to find the difference between the predicted number of attendees and the actual number of attendees, and then divide it by the predicted number. Here's how you can calculate it:
1. Find the difference: Subtract the actual number of attendees from the predicted number.
Predicted number of attendees = 275
Actual number of attendees = 265
Difference = Predicted number of attendees - Actual number of attendees
Difference = 275 - 265 = 10
2. Calculate the percent error: Divide the difference by the predicted number and multiply by 100 to get the percent error.
Percent Error = (Difference / Predicted number of attendees) * 100
Percent Error = (10 / 275) * 100
Now, we can calculate the percent error:
Percent Error = 0.036363636 * 100
Percent Error ≈ 3.64%
Therefore, the percent error in Julian and Brittany's prediction is approximately 3.64%.
