A​ student's course grade is based on one midterm that counts as ​% of his final​ grade, one class project that counts as ​% of
Andrei [34K]

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

<u>Proportion:</u>

Midterm = 15\%

Project = 25\%

Assignment = 40\%

Exam = 20\%

Scores

Midterm = 66

Project = 90

Assignment = 75

Exam = 66

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66

Overall = 9.9 + 22.5 + 30 + 13.2

Overall = 75.6

Solving (b): The letter grade

From the question, we have:

A: Mean \ge 90

B: 80 \le Mean < 90

C: 70 \le Mean < 80

The overall score falls in the following category:

C: 70 \le Mean < 80

Because:

70 \le 75.6 < 80

<em>Hence, the letter grade is C</em>
