Answer:
d(x)=-750x^2-3750x-10500
Step-by-step explanation:
The manager of a department store uses the given function to model the monthly opening inventory of down comforters at the store, in dollars, where x represents the number of months from September.
d(x)=-750(x^2-5x-14)
To rewrite this hat reveals the store's opening inventory of down comforters in the month of September, multiply -750 on the bracket, we get
d(x)=-750x^2-3750x-10500
Answer:
b) Binomial
c) Poisson
Step-by-step explanation:
The geometric distribution is the number of trials required to have r successes. The measures the number of sucesses(wins), not the number of trials required to win r games. So the geometric distribution does not apply.
For each match, there are only two possible outcomes, either the skilled player wins, or he does not. The probability of the skilled player winning a game is independent of other games. So the binomial distribution applies.
We can also find the expected number of wins of the skilled player, which is 15*0.9 = 13.5. The Poisson distribution is a discrete distribution in which the only parameter is the expected number of sucesses. So the Poisson distribution applies.
So the correct answer is:
b) Binomial
c) Poisson
Answer: C. x=0, y=2, z=5
