Question

Bot 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.

Answer 1

Bot is that your final answer?

Answer 2

To find Teresa's percent error, we can use the formula:

Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100

Given that Teresa estimated the height of the giraffe as 18 feet, and the actual height is 16 feet, we can calculate the percent error.

Percent Error = (|18 - 16| / 16) * 100

Simplifying, we have:

Percent Error = (2 / 16) * 100

Percent Error = 0.125 * 100

Percent Error = 12.5%

Therefore, Teresa's percent error is 12.5%.

Answer 3

Apologies for the confusion in my previous response. After recalculating, the correct answer is as follows:

Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100
Percent Error = (|18 - 16| / 16) * 100
Percent Error = (2 / 16) * 100
Percent Error = 0.125 * 100
Percent Error = 12.5%

Therefore, Teresa's percent error is 12.5%.
