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>
