Teresa estimates that the height of a giraffe in a zoo is 18 feet in fact it is 16 feet tall what is Teresa percent error use proportional relationships to solve the problem show all your work and round your answer to the nearest tenth!!
To find Teresa's percent error, we need to compare her estimate to the actual height and calculate the difference as a percentage of the actual height.
The formula to calculate percent error is:
Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100
Substituting the given values:
Estimated Value = 18 feet
Actual Value = 16 feet
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%.
