Answer:
The average final score = 82.58
Step-by-step explanation:
we have given,
Grading Scale 1 has the following weights :-
Tests- 50% , Quiz- 25% , Homework- 15% and Final Exam- 10%
Total % marks obtained in tests = [tex]\frac{88+84+90+75+70+81}{600} *100[/tex] = 81.33%
Total % marks obtained in quiz =[tex]\frac{88+67+90+90+45+99+76+98+100}{900} * 100[/tex] = 83.66%
Home work score = 90
final exam score = 75
Now, Weight of tests grade = 50% of 81.33 = 40.665
Weight of quiz grade = 25% of 83.66 = 20.915
Weight of homework = 15% of 90 = 13.5
Weight of final exam = 10% of 75 = 7.5
So the average final score = 40.665 + 20.915 + 13.5 + 7.5 = 82.5
