Answer:
0.15 = 15% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
![P(X > x) = \frac{b - x}{b - a}](https://tex.z-dn.net/?f=P%28X%20%3E%20x%29%20%3D%20%5Cfrac%7Bb%20-%20x%7D%7Bb%20-%20a%7D)
Uniformly distributed between 0 and 5 minutes.
This means that ![a = 0, b = 5](https://tex.z-dn.net/?f=a%20%3D%200%2C%20b%20%3D%205)
Find the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.
![P(X > 4.25) = \frac{5 - 4.25}{5 - 0} = 0.15](https://tex.z-dn.net/?f=P%28X%20%3E%204.25%29%20%3D%20%5Cfrac%7B5%20-%204.25%7D%7B5%20-%200%7D%20%3D%200.15)
0.15 = 15% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

Answer:
D. 25
Step-by-step explanation:
By geometric mean property:
![{(12)}^{2} = LM\times JM \\ \\ 144 = LM\times16 \\ \\ LM = \frac{144}{16} \\ \\ LM = 9 \\ \\](https://tex.z-dn.net/?f=%20%7B%2812%29%7D%5E%7B2%7D%20%3D%20%20LM%5Ctimes%20JM%20%5C%5C%20%20%5C%5C%20144%20%3D%20LM%5Ctimes16%20%5C%5C%20%20%5C%5C%20LM%20%3D%20%20%5Cfrac%7B144%7D%7B16%7D%20%20%5C%5C%20%20%5C%5C%20LM%20%3D%209%20%5C%5C%20%20%5C%5C%20)
JL = JM + LM = 16 + 9 = 25
