Answer:
The answer is 150
Step-by-step explanation:
It's 150 because ye evening sales are three times of his afternoon sales.
SO that means you have to times 50x3=150 or you can add 50+50+50=150. there is your answer.
Expected value of the bet is
the sum of the products of value of outcome and its probability,
less the amount paid to place the bet.
Outcomes value probability
win 225 1/4
lose 0 3/4
cost of bet = 40
So expected value of bet
E[X]=225*(1/4)+0*(3/4)-40
=56.25-40
=16.25
This means that in the long run, gambler will win, since the expected value is positive. (does NOT mean she will win in the next bet!)
The function:f ( x ) = x * 0.965^twhere x is the initial amount and t is the number of the years80 = x * 0.965^380 = x * 0.89632x = 80 : 0.89632 ≈ 89Answer:The initial amount of animals was 89.
C. 452.16
use formula pir^2
12^2 = 144
144 x 3.14 = 452.16
