Jason, a freshman at a local college, just completed 15 credit hours. His grade report is presented below.
Course: Calculus, Biology, English, Music, P.E.
Credit Hours 5, 4, 3, 2, 1
Grades C, A, D, B, A
The local university uses a 4 point grading system, i.e., A = 4, B = 3, C = 2, D = 1, F = 0. Compute Jason's semester grade point average.
The answer is 2.6 but I'm not sure how to get that
Grade points times credit hours divided by total credit hours.
[(5*4) + (4*3) + (3*1) + (2*3) + (1*4)]/15 = ?
I added his points: 2+4+1+3+4=14 and divided it by 5 to get 2.8 but that's the wrong answer.
There are 71 students in all. The height of the 60-to-65 inch rectangle is about 0.0507. How many students are between 60 and 65 inches in height? Give a whole number answer.
12
Well, let's break this down, shall we? Jason completed 15 credit hours, and we have the grades for each course.
His grades are C, A, D, B, A, which correspond to the grade point values of 2, 4, 1, 3, 4.
Now we multiply each grade point value by the respective credit hours. For Calculus: 5 credit hours * 2 grade points = 10 grade points. For Biology: 4 credit hours * 4 grade points = 16 grade points. For English: 3 credit hours * 1 grade point = 3 grade points. For Music: 2 credit hours * 3 grade points = 6 grade points. For P.E.: 1 credit hour * 4 grade points = 4 grade points.
Now we add up all the grade points: 10 + 16 + 3 + 6 + 4 = 39 grade points.
Finally, we divide the total grade points by the total credit hours: 39 grade points / 15 credit hours = 2.6.
So Jason's semester grade point average is 2.6. He's doing alright, but maybe he should consider asking the clown professor for some extra credit!
To compute Jason's semester grade point average, we need to multiply the credit hours of each course by the corresponding grade points for that course. Then we sum up all these values and divide by the total number of credit hours.
Let's calculate it step by step:
1. Multiply each credit hour by the corresponding grade points:
Course: Calculus
Credit Hours: 5
Grade: C
Grade Points = 2 (C)
Grade Points for Calculus = Credit Hours * Grade Points = 5 * 2 = 10
Course: Biology
Credit Hours: 4
Grade: A
Grade Points = 4 (A)
Grade Points for Biology = Credit Hours * Grade Points = 4 * 4 = 16
Course: English
Credit Hours: 3
Grade: D
Grade Points = 1 (D)
Grade Points for English = Credit Hours * Grade Points = 3 * 1 = 3
Course: Music
Credit Hours: 2
Grade: B
Grade Points = 3 (B)
Grade Points for Music = Credit Hours * Grade Points = 2 * 3 = 6
Course: P.E.
Credit Hours: 1
Grade: A
Grade Points = 4 (A)
Grade Points for P.E. = Credit Hours * Grade Points = 1 * 4 = 4
2. Sum up all the grade points:
Total Grade Points = Grade Points for Calculus + Grade Points for Biology + Grade Points for English + Grade Points for Music + Grade Points for P.E.
Total Grade Points = 10 + 16 + 3 + 6 + 4 = 39
3. Sum up all the credit hours:
Total Credit Hours = Credit Hours for Calculus + Credit Hours for Biology + Credit Hours for English + Credit Hours for Music + Credit Hours for P.E.
Total Credit Hours = 5 + 4 + 3 + 2 + 1 = 15
4. Compute the grade point average:
Grade Point Average (GPA) = Total Grade Points / Total Credit Hours
GPA = 39 / 15 = 2.60
Therefore, Jason's semester grade point average is 2.60.
