Answer:
<u><em>D. 95</em></u>
Step-by-step explanation:
The average is also known as the mean. To find the mean, you need to add all the values, then divide them by the number of terms:
1 2 3
1+2+3
6/3=2
The mean for the example would be 2. Now, using your values, you can use the options to see which one gives you an average of 90:
A.) 85
B.) 90
C.) 92
D.) 95
The next score on the quiz needs to be 90 for the mean to be 90.
