A. 92.25
B. 93.5
C. 93.75
D. 94.25
it 92.25
the mean is the average
(92 + 94 + 100 + 83) / 4
To calculate the mean quiz score, you need to find the sum of all the quiz scores and divide it by the number of quizzes taken.
In this case, Mariah took 4 quizzes with scores of 92, 94, 100, and 83.
To find the sum of the quiz scores, you add them all together:
92 + 94 + 100 + 83 = 369
Next, you divide the sum of the quiz scores by the number of quizzes taken, which is 4:
369 / 4 = 92.25
Therefore, Mariah's mean quiz score is 92.25.
So, the correct answer is A. 92.25.
