PLEASE HELP ASAP!!! A talent competition on television had five elimination rounds. After each elimination, only one-third of th
e contestants were sent to the next round. The table below shows the number of contestants in each round of the competition: x 1 2 3 4 5 f(x) 243 81 27 9 3 Compute the average rate of change of f(x) from x = 1 to x = 4 and describe what it represents. A) −78 contestants per round, and it represents the number of contestants who will reach the final round
B)−234 contestants per round, and it represents the number of contestants who will reach the final round
C)−234 contestants per round, and it represents the average rate at which the number of contestants changed from the first round to the fourth round
D) −78 contestants per round, and it represents the average rate at which the number of contestants changed from the first round to the fourth round
(9-243)/(4-1)=-78 D)−78 contestants per round, and it represents the average rate at which the number of contestants changed from the first round to the fourth roundReport · <span>14/12/2015</span>
Analogously, between 3rd and 2nd points and between 4th and 3rd points:
27 - 81 = -54
9 - 27 = -18
Therefore, the average rate of change is (-162 -54 -18)/3 = -78 contestants per round, and it represents the average rate at which the number of contestants changed from the first round to the fourth round

Probability hit=40%=4/10 probability no hit=1-p (hit)=1-4/10=6/10 probability= p(hit)+p(hit)+p(hit)+p(hit)+p(hit)+p (no hit)+p (no hit)+p (no hit) probability=4/10×4/10×4/10×4/10×4/10×6/10×6/10×6/10 =0.0022 ( I think but I'm not 100% sure)
