Multiply 8.5 by 12, multiply 7.5 by 20, add them together to get 252, then divide that by 32 to get 7.875. 7.875 is the mean of all 32 measurements

Answer:
92.5
Step-by-step explanation:
The total of Megan's scores is ...
94 +81 +87 +93 = 355
so her current average is 355/4 = 88.75
The score (s) Megan needs for a 90 average is ...
(2/3)(88.75) +(1/3)s = 90
2(88.75) +s = 270 . . . . . . . . multiply by 3
s = 270 -177.5 = 92.5
Megan needs a score of 92.5 on her final to have an overall average of 90.
The probability expression is 
<h3>How to determine the probability expression?</h3>
The given parameters are
- Sophomore = 6
- Freshmen = 14
The total number of people is
n = 20
2 of the 20 people are to be selected.
So, the number of selection is

This gives

The expression that represents both students being sophomore is
--- i.e. 2 students selected from 6
The probability is then represented as:

Hence, the probability expression is
