Answer:
C.) 3 h
Step-by-step explanation:
If you assume the distance is proportional to the charge time, then ...
x/5 = 65/107
x = 5(65/107) ≈ 3.04
The car may have held about a 3-hour charge.
Answer:
the probability that more than 9 but fewer than 14 disapprove of smoking pot daily is 0.608
Step-by-step explanation:
From the information given:
Let N represent the total number of senior students
N = 17000
and k to be the number of seniors disapproving of daily pot smoking
k = 17000 × 0.70
k = 11900
sample size n = 18
Suppose X represents the random variable...
Then,
X = 0,1,2,...,18
Thus X follows a hypergeometric distribution with parameters
(N = 17000, n = 18 & k = 11900)
Thus, the probability mass function is:
![P(X =x) = \dfrac{(^k_n) (^{N-k}_{n-x} ) }{(^N_n) }; \ max \{0,(N-K) \} \le x \le min \{n,k\}](https://tex.z-dn.net/?f=P%28X%20%3Dx%29%20%3D%20%5Cdfrac%7B%28%5Ek_n%29%20%28%5E%7BN-k%7D_%7Bn-x%7D%20%29%20%7D%7B%28%5EN_n%29%20%7D%3B%20%20%5C%20max%20%5C%7B0%2C%28N-K%29%20%5C%7D%20%5Cle%20x%20%5Cle%20min%20%5C%7Bn%2Ck%5C%7D)
![P(X =x) = \dfrac{(^{11900}_n) (^{17000-11900}_{18-x} ) }{(^{17000}_{18}) }](https://tex.z-dn.net/?f=P%28X%20%3Dx%29%20%3D%20%5Cdfrac%7B%28%5E%7B11900%7D_n%29%20%28%5E%7B17000-11900%7D_%7B18-x%7D%20%29%20%7D%7B%28%5E%7B17000%7D_%7B18%7D%29%20%7D)
![P(X =x) = \dfrac{(^{11900}_n) (^{51000}_{18-x} ) }{(^{17000}_{18}) }; \ 0\le x \le 18](https://tex.z-dn.net/?f=P%28X%20%3Dx%29%20%3D%20%5Cdfrac%7B%28%5E%7B11900%7D_n%29%20%28%5E%7B51000%7D_%7B18-x%7D%20%29%20%7D%7B%28%5E%7B17000%7D_%7B18%7D%29%20%7D%3B%20%5C%200%5Cle%20x%20%5Cle%2018)
Now, the required probability is computed as:
![P(9](https://tex.z-dn.net/?f=P%289%3CX%3C14%29%20%3D%20P%2810%20%5Cle%20X%20%5Cle13%29)
![P(9](https://tex.z-dn.net/?f=P%289%3CX%3C14%29%20%3D%20P%28X%20%3D10%29%20%2BP%28X%20%3D11%29%20%2BP%28X%3D12%29%20%2BP%28X%20%3D13%29)
P(9<X<14) = 0.0811 + 0.1377 + 0.1874 + 0.2018
P(9<X<14) = 0.608
Thus, the probability that more than 9 but fewer than 14 disapprove of smoking pot daily is 0.608
