Answer:
-1/7=n
Step-by-step explanation:
We can use cross products to solve
5 7
-------- = ------
n+3 4
5*4 = 7*(n+3)
20 = 7*(n+3)
Distribute
20 = 7n+21
subtract 21 from each side
20-21 = 7n+21-21
-1 = 7n
Divide each side by 7
-1/7 = 7n/7
-1/7=n
Answer:
it would be C because they don't give enough information
Answer:
P(x = 0) = 0.004
P(x = 0) = 0.047
P(x = 0) = 0.211
P(x = 0) = 0.422
P(x = 0) = 0.316
Step-by-step explanation:
We are given the following information:
We treat a person who does not become a repeat offender as a success.
P(Success) = P(person who does not become a repeat offender) = 0.75
Then the number of people follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 4
We have to evaluate:
![P(x = 0)\\= \binom{4}{0}(0.75)^0(1-0.75)^4 = 0.004](https://tex.z-dn.net/?f=P%28x%20%3D%200%29%5C%5C%3D%20%5Cbinom%7B4%7D%7B0%7D%280.75%29%5E0%281-0.75%29%5E4%20%3D%200.004)
![P(x = 1)\\= \binom{4}{1}(0.75)^1(1-0.75)^3 = 0.047](https://tex.z-dn.net/?f=P%28x%20%3D%201%29%5C%5C%3D%20%5Cbinom%7B4%7D%7B1%7D%280.75%29%5E1%281-0.75%29%5E3%20%3D%200.047)
![P(x = 2)\\= \binom{4}{2}(0.75)^2(1-0.75)^2 = 0.211](https://tex.z-dn.net/?f=P%28x%20%3D%202%29%5C%5C%3D%20%5Cbinom%7B4%7D%7B2%7D%280.75%29%5E2%281-0.75%29%5E2%20%3D%200.211)
![P(x = 3)\\= \binom{4}{3}(0.75)^3(1-0.75)^1 = 0.422](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%5C%5C%3D%20%5Cbinom%7B4%7D%7B3%7D%280.75%29%5E3%281-0.75%29%5E1%20%3D%200.422)
![P(x = 4)\\= \binom{4}{4}(0.75)^4(1-0.75)^0 = 0.316](https://tex.z-dn.net/?f=P%28x%20%3D%204%29%5C%5C%3D%20%5Cbinom%7B4%7D%7B4%7D%280.75%29%5E4%281-0.75%29%5E0%20%3D%200.316)
