Question

A student's course grade is based on one midterm that counts as

20%

of his final grade, one class project that counts as

25%

of his final grade, a set of homework assignments that counts as

50%

of his final grade, and a final exam that counts as

of his final grade. His midterm score is

63,

his project score is

82,

his homework score is

90,

and his final exam score is

70.

What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.

His overall final score is

nothing.

(Type an integer or a decimal rounded to one decimal place as needed.)

His letter grade is

(1)

Expert Solution

Step 1

The way to deal with settle this inquiry is to understand that the imprints must be changed over into the separate rates of the entire course. This implies that the signs of the multitude of parts must be standardized by the evaluating breakdown.

Total score = (63*20/100) + (82*25/100) + (90 *50/100) + (70*5/100)

= 12.6 + 20.5 + 45 + 3.5

=81.6

So, his letter grade will be B as it is less than 90 and greater than 80
