Teresa estimates that the height of a giraffe in a zoo is 18 feet in fact it is 16 feet tall what us Teresa’s percent error? Use proportional relationship to solve the problem be sure to show work to get the answer as a percent and round to nearest tenth
To find Teresa's percent error, we use the formula:
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.
Percent Error = (|18 - 16| / 16) * 100
= (2 / 16) * 100
= 0.125 * 100
= 12.5
Therefore, Teresa's percent error is 12.5%.
