Question

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

1010​%

of his final​ grade, one class project that counts as

1515​%

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

4545​%

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

3030​%

of his final grade. His midterm score is

6969​,

his project score is

9494​,

his homework score is

9292​,

and his final exam score is

6767.

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.

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

Answer 1

midterm =10%

class project = 15%

homework assignment=45%

final exam = 30%

Mid term = 69

Project Score=94

homework assignment=92

final exam = 67

Assumption: all the scores are out of 100

Over all % = Mid term*Wtg Mid term + Project Score*Wtg Project Score + homework assignment*Wtg homework assignment + final exam*Wtg final exam

=10% * 69 + 15% * 94 + 45% * 92 + 30% * 67

=82.5%

So the final grade of the student is 82.5%

a mean of at least 80 but less than 90 is a​ B and hence the grade is B
