Teresa estimates that the height of a giraffe in a zoo is 18 feet in fact it is 6 feet tall. What is Teresa’s percent error use proportional relationship to solve this problem so all your work, and Roger answered to the nearest 10th

Answer 1

To find the percent error, we can use the formula:

Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100

Given that Teresa estimated the giraffe's height to be 18 feet and the actual height is 6 feet, we can substitute these values into the formula:

Percent Error = (|18 - 6| / 6) * 100
Percent Error = (12 / 6) * 100
Percent Error = 2 * 100
Percent Error = 200

Therefore, Teresa’s percent error is 200%.
