Exam 3 (Out of 99.84) 94.36
Exam 4 (Out of 100.00) 64.00

Answer 1

Compute your grade using a weighted average.

(.02)(1.00) +
(.20)( (85.1/99.9) + (80.00/100.00) + (94.36/99.84) + (64.00/100.00) +
(.18)(1.00)

Answer will be as a percentage; that is, .847 = 84.7%

Answer 2

Category 1 (18%):
Writing Project (Out of 100.00) 100.00
.18 * 100= 18

Category 2(2%):
Introductory Assignment (Out of 100.00) 100.00
.02 * 100=2

Category 3(80%):
Exam 1 (Out of 99.90) 85.10
Exam 2 (Out of 100.00) 80.00
Exam 3 (Out of 99.84) 94.36
Exam 4 (Out of 100.00) 64.00
total=323.46/400, or 80.865/100
.80 * 80.865=64.692

add all your percents up:
64.692 + 2 + 18 = 84.692

Answer 3

Sum of the following:

1) 100*.18 = 18
2) 100*.02 = 2
3) (85.1/99.9 + 80/100 + 94.36/99.84 + 64/100) 100 * .2, or
64.74

84.74

Answer 4

.18*100= 18

2. EXAMS

.851 * 20 = 17.02
80%
.8*20 = 16
94.36%
.9436*20= 18.872
64%
.64*20= 12.8
3. INTRO
