To calculate the percent error, you first need to find the difference between the predicted number of attendees and the actual number of attendees.
Predicted number of attendees = 275
Actual number of attendees = 265
Difference = Predicted number of attendees - Actual number of attendees
Difference = 275 - 265
Difference = 10
Next, divide the difference by the predicted number of attendees and multiply by 100 to get the percent error.
Percent error = (Difference / Predicted number of attendees) * 100
Percent error = (10/275) * 100
To the nearest hundredth percent, the percent error is approximately 3.64%.
To calculate the percent error, we use 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
Calculating it:
Percent Error = (10 / 265) * 100
Percent Error ≈ 3.77%
Therefore, the percent error in their prediction is approximately 3.77%.
To calculate the percent error, we need to find the difference between the predicted value and the actual value, and then divide that difference by the actual value. Finally, we multiply the result by 100 to get the percentage:
Predicted value = 275
Actual value = 265
Difference = Predicted value - Actual value = 275 - 265 = 10
Percent Error = (Difference / Actual value) * 100
Percent Error = (10 / 265) * 100
Now we can calculate the percent error:
Percent Error = 3.77%
Therefore, the percent error in their prediction is 3.77%.
