Teresa estimates that the height of a giraffe in a zoo is 18 feet in fact it is 16 feet tall what is Teresa percent error use proportional relationships to solve the problem show all your work and round your answer to the nearest tenth
To find the percent error, we need to compare the estimated height to the actual height and express the difference as a percentage of the actual height.
Percent error formula: (|Estimated value - Actual value| / Actual value) * 100
Given data:
Estimated height = 18 feet
Actual height = 16 feet
Step 1: Find the difference between the estimated and actual values:
|18 - 16| = 2 (absolute value is taken to remove any negative signs)
Step 2: Divide the difference by the actual value and multiply by 100 to find the percentage:
(2 / 16) * 100 = 12.5
Therefore, Teresa's percent error is 12.5%.
