teresa estimate that the height of a giraffe in a zoo is 18 feet in fact it is 16 feet tall waht is teresas percent error

Answer 1

To find Teresa's percent error, we first need to calculate the difference between her estimate and the actual value:

Actual value = 16 feet
Estimated value = 18 feet

Difference = Actual value - Estimated value = 16 - 18 = -2.

Next, we find the absolute value of this difference:
Absolute value of -2 = 2.

Then, we find the relative error by dividing this absolute difference by the actual value and multiplying by 100%:
Relative error = (2 / 16) * 100% = 12.5%.

Therefore, Teresa's percent error is 12.5%.
