Teresa estimates that the height of a giraffe in a zoo is 18 feet. In fact, it is 16 feet tall. What is Teresa’s 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.(4 points)
To calculate the percent error, we can use the formula: Percent Error = (|measured value - actual value| / actual value) x 100. In this case, Teresa estimated the height of the giraffe to be 18 feet, while the actual height is 16 feet. Therefore, the percent error is calculated as (|18 - 16| / 16) x 100 = (2 / 16) x 100 = 12.5%. So, Teresa's percent error in estimating the height of the giraffe in the zoo is 12.5%.
