Subtract c and then x = y - c
And that's it!
63 = 9k
divide by 9 on each side to get k by itself
k = 7
Answer:
Some of the 50 students should have been assigned to a control group that used the in-person course
Step-by-step explanation:
Answer:
C(t) = 20t
Step-by-step explanation:
The graph of C(t) appears to be linear
The y intercept is 0
The slope is 200/10 = 20
y = mx+b where m is the slope and b is the y intercept
y = 20x+0
y = 20x
C(t) = 20t
