Answer :

To determine the percent of error in Kinzie's guess, we can first calculate the absolute error by taking the absolute difference between her guessed score and the actual score. Kinzie's guessed score: 89 Kinzie's actual score: 83 Absolute error = |guessed score - actual score| = |89 - 83| = 6 Now that we have found the absolute error, we can calculate the percent of error. This is given by the formula: Percent of error = (Absolute error / Actual score) * 100% Plugging the numbers into the formula: Percent error = (6 / 83) * 100% ≈ 7.2289% When rounding this to the nearest tenth of a percent, we get: Percent error ≈ 7.2% So, the percent of error in Kinzie's guess is 7.2%.
