The overall course average is the average weight of all the quizzes, tests, finals, labs.

First we need the average for all the information:

Quiz Average: 95 (given)

Lab Average: 89 (given)

Test Average >> we have to find by summing and dividing by number of tests


\text{average}=(52+82+88)/(3)=74

Final Exam: 73 (1 exam, so this is the average).

Thus, the information we have:

Quiz Avg = 95

Lab Avg = 89

Test Avg = 74

Final Avg = 73

Now, we multiply the scores with the respective weightage(in decimal) and sum it. We get:


95\mleft(0.25\mright)+89\mleft(0.25\mright)+74\mleft(0.35\mright)+73\mleft(0.15\mright)=82.85

Rounded to nearest whole number: 83

Answer:

Course Average = 83 (rounded to nearest whole number)
