Answer 1

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

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

By substituting the given values:

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

Simplifying:

Percent Error = (2 / 16) * 100%

Percent Error = 0.125 * 100%

Percent Error = 12.5%

Therefore, Teresa's percent error is 12.5%.

Answer 2

make it kinda like a very short essay or maybe a sentence

Answer 3

The percent error of Teresa's estimate is 12.5%. This means that her guess of 18 feet for the giraffe's height was 12.5% off from the actual height of 16 feet.
