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
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%.
