Answer:
- A. 79.4
- B. 84
- C. Science class
Step-by-step explanation:
<u>Average test score in math class</u>
<u>Average test score in science class</u>
As per table the rate of change is -2, therefore g(x) is
- g(x) = -2x + 88, because
- g(1) = -2 + 88 = 86
<u>Part A: Determine the test average for your math class after completing test 2. </u>
-
f(2) = 0.2*2 + 79 = 0.4 + 79 = 79.4
<u>Part B: Determine the test average for your science class after completing test 2</u>
-
g(2) = 84 given in the table
<u>Part C: Which class had a higher average after completing test 4? </u>
- f(4) = 0.2*4 + 79 = 0.8+ 79 = 79.8
- g(4) = -2*4 + 88 = - 8 + 88 = 80
Science class had higher class
Answer:
50 cups
Step-by-step explanation:
ratio of water to juice = 10 : 6 = 5 : 3
amount of cup = (5 x 30) / 3 = 50
