Answer:
2(s-c)/ a^2 = v
Step-by-step explanation:
s = 1/2 a^2 v+c
Subtract c from each side
s -c = 1/2 a^2 v+c-c
s-c = 1/2 a^2 v
Multiply each side by 2
2(s-c) = 2* 1/2 a^2 v
2(s-c) = a^2 v
Divide each side by a^2
2(s-c)/ a^2 = a^2 v /a^2
2(s-c)/ a^2 = v

Answer:
The weighted mean grade is 78.62
Step-by-step explanation:
We are given the following in the question:
Regular exam score = 79, 74, and 73
Weightage of regular exam = 12%
Final exam grade = 66
Weightage of final exams = 17%
Course project grade = 88
Weightage of project = 10%
Homework grade = 93
Weightage of homework = 37%
Mean of regular exam scores =

Weighted mean grade


The weighted mean grade is 78.62
