Teresa estimates the height of a giraffe and a zoo is 18 feet in fact, it is 16 feet tall. What is Teresa's percent error use proportional relationships to solve the problem. Be sure to show all your work provide your answer as a percentage and round your answer to the nearest tenth
To find Teresa's percent error, we need to compare her estimate to the actual height and calculate the difference.
Actual height: 16 feet
Estimated height: 18 feet
Difference = Estimated height - Actual height
Difference = 18 - 16 = 2 feet
Now, we need to find the percent error by dividing the difference by the actual height, and then multiplying by 100.
Percent error = (difference / actual height) * 100
Percent error = (2 / 16) * 100 ≈ 0.125 * 100 ≈ 12.5
Therefore, Teresa's percent error is approximately 12.5%.
