Julian and Brittany man 275 wedding invitations and family and friends and predicted that they would all attend only 265 275 PO committed to attend the money. Calculate the percent in the prediction your answer the nearest hundred percent.

Answer 1

To calculate the percentage difference between the number of invitations sent and the number of predicted attendees, we can use the following formula:

$$\text{Percentage Error}=\left(\frac{\text{Actual Value}-\text{Predicted Value}}{\text{Actual Value}}\right)\times 100$$

In this case:

• Actual Value (invitations) = 275
• Predicted Value (expected attendees) = 265

Now we can substitute these values into the formula:

$$\text{Percentage Error}=\left(\frac{275-265}{275}\right)\times 100$$

Calculating this gives:

$$\text{Percentage Error}=\left(\frac{10}{275}\right)\times 100\approx 3.64$$

Thus, rounding to the nearest hundredth of a percent, the prediction error is approximately 3.64%.
