Answer:
3 Credit Courses = 37
4 Credit Courses = 11
Step-by-step explanation:
1. Set up 2 equations:
3x + 4y = 155
x + y = 48
2. Simplify the second expression for x by subtracting y from both sides
x = 48 - y
3. Substitute 48 - y for x
3(48-y) + 4y = 155
4. Simplify the expression by multiplying by 3
144 - 3y +4y = 155
5. Subtract 144 from both sides and subtract 3y from 4y
y = 11 = 4 Credit Courses
6. Substitute y for equation 2
x = 48-11
7. solve for x
x = 37 = 3 Credit Courses
Answer:
46%
Step-by-step explanation:
For percents, we want to make the number out of 100. 23/50 is the same as 46/100. From fraction knowledge, 46/100 is 46%.
Answer:
71.4699, 81.7301.
Step-by-step explanation:
So, the following are the scores: 74
90
84
78
61
65
62
67
73
75
76
95
71
98
80
The length of the score : 15
Then, let the size of the scores be n : 15.
Then, we have to find the mean.
Only graph 5 is a function because if you do the vertical line test, you draw a vertical line anywhere on the graph. If the parabola crossed the line twice it would not be a function.
