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 and Round your answered to the nearest 10th
To find the percent error, we need to calculate the difference between the estimated height and the actual height, and then divide that by the actual height. Finally, we multiply by 100 to get the percentage.
Estimated height: 18 feet
Actual height: 6 feet
Difference: 18 - 6 = 12 feet
Percent error = (Difference / Actual height) * 100
= (12 / 6) * 100
= 2 * 100
= 200%
Therefore, Teresa's percent error is 200%.
