the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
Answer:
(B) 10
Step-by-step explanation:
Rate of change is basically slope
So the slope here is 10/1 so the rate of change is 10
Note that there's a strict order here -> 2 close friends, then 1 non-close friend.
So, picking in order:
probability of picking the first close friend: 4/10
probability of picking the second close friend: 3/9
probability of picking the first non-close friend: 6/8
So, we get 4/10 * 3/9 * 6/8 = 1/10.
