X and y vary directily means
y=kx
72=3k
divide both sides by 3
24=k
k=24
y=72
Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
Answer:
omg i can't do that
Step-by-step explanation:
P(H) = 1/2
P(>6) = 9/15 = 3/5
P(Both H AND >6) = 1/2 * 3/5 = 3/10
