Answer:
The mean score is 13.5 points per question.
Step-by-step explanation:
Leonard took ten 15-point quizzes in his geometry class.
His total points on the 10 quizzes is 135.
We expect him to score 10 × 15 = 150 points , if he got all the questions right.
But now he scores 135 points in the 10 questions.
The mean score = Total points scored ÷ tota number of questions
i.e the mean score = 135 ÷ 10 = 13.5
So Leonard scored 13.5 points per question.
