wrong for both of you try again
To find the percentage error, we need to calculate the difference between the believed weight and the actual weight, and then divide it by the actual weight. Finally, we multiply the result by 100 to get the percentage.
Let's calculate step by step:
1. Calculate the difference between the believed weight and the actual weight: 75 - 55 = 20 pounds.
2. Divide the difference by the actual weight: 20 / 75 = 0.2667
3. Multiply the result by 100 to get the percentage: 0.2667 * 100 = 26.67
So, the percentage error is 26.67%.
Rounded to the nearest hundredth, the percentage error is 26.67%.
The percentage error is 36.36%.
I would do it this way:
error = 75-55 = 20
percent error = 20/75 = .2666.. = 26.7%
