Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

3.40

Step-by-step explanation:

Given :  

A student earned grades of C, A, B, and A in four different courses.

Those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5.

The grading system assigns quality points to letter grades as follows: A = 4, B = 3, C = 2, D = 1, and F = 0.

To Find: Compute the grade point average (GPA) and round the result to two decimal places.

Solution :

The grades earned are C, A, B, and A

Since . The grading system assigns quality points to letter grades as follows: A = 4, B = 3, C = 2, D = 1, and F = 0.

So the earned grades  C=2 , A=4 , B=3 , A =4

Their corresponding numbers of credit hours are 4,5,1,5

Formula of GPA   =

                             =

                             =

                             =

                             = 3.40

Hence the grade point average (GPA) is 3.40

-3.6

Step-by-step explanation:

z/(-2) + -5 = -3.2 → times -2

z + 10 = 6.4

z = 6.4 - 10

z = -3.6
