Answer:

89.84375

Step-by-step explanation:

Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.

To find weighted mean.

Here weights can be considered as number of majors in each subject

$Marks x 90 85 93\\Weights 15 7 10\\Product 1350 595 930\\$

Weighted total = 1350+595+930 = 2875

Weighted mean = weighted total/total students

$=\frac{2875}{32} =89.84375$
