teresa estimates that the Height of a giraffe in a zoo is 18 feet tall in fact it is 16 feet tall what is teresas percent error use proportional relationships to solve the problem be sure to show all your work provide your answer as a percentage and round your answer to the nearest tenth MAKE IT SIMPLE
The percent error can be calculated using the formula:
Percent Error = (|True Value - Estimated Value| / True Value) * 100
Given that the estimated height is 18 feet and the actual height is 16 feet, we can plug these values into the formula:
Percent Error = (|16 - 18| / 16) * 100
Simplifying this expression:
Percent Error = (|-2| / 16) * 100
= (2 / 16) * 100
Dividing 2 by 16:
Percent Error = 0.125 * 100
= 12.5
Therefore, Teresa's percent error is 12.5%.
