Question

Teresa estimates that the height of a giraffe in a zoo is 18 feet. In fact, it is 16 feet tall. What is Teresa is percent error? Do you spell portional relationship to solve the problem. Round your answer to the nearest tenth.

Answer 1

The formula for percent error is given by:

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

In this case, the measured value is 18 feet and the actual value is 16 feet.

Using the formula, we can calculate the percent error:

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%.
