Teresa estimated that the giraffe in the zoo was 18 feet tall, but it is actually 16 feet tall. To find her percent error, we need to compare the difference between her estimate and the actual height to the actual height.
First, we find the difference between her estimate and the actual height: 18 feet - 16 feet = 2 feet.
Next, we divide the difference by the actual height: 2 feet / 16 feet = 0.125.
To express this as a percentage, we multiply by 100: 0.125 * 100 = 12.5%.
Therefore, Teresa's percent error is 12.5%.
Teresa estimates that the height of a giraffe in 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.(4 points) makw it short and sound like a 7th grader
