The error in the weatherman's prediction is the absolute value of the difference between the predicted temperature and the actual temperature: |64 - 38| = 26.
The percent error is then calculated by dividing this error by the predicted temperature and multiplying by 100%: (26/64) * 100% = 40.63%.
Therefore, the answer is B. 40.63%.
The weatherman predicted that today's temperature would be 64°F. It was actually 38°F. What was the percent error of the weatherman's prediction?
