Tresa estimates that the height of a giraffe and a zoo is 18 feet in fact it is 16 feet tall what is trusses percent air use proportional relationship to solve the problem show all your work and round your answer to the nearest 10th
To find Tresa's percent error in estimating the height of the giraffe, we need to use the formula for percent error:
Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100%
Given:
Estimated Value (E) = 18 feet
Actual Value (A) = 16 feet
Plugging in the values into the formula:
Percent Error = (|18 - 16| / 16) * 100%
Calculating the numerator inside the absolute value:
|18 - 16| = |2| = 2
Now calculating the percent error:
Percent Error = (2 / 16) * 100%
Simplifying the fraction:
Percent Error = (1/8) * 100%
Evaluating the expression:
Percent Error = 12.5%
Therefore, Tresa's percent error in estimating the height of the giraffe is 12.5%.
