Answer:
4
Step-by-step explanation:
Think of two numbers that will go to 96. The best numbers you can use are 16 and 6. You would need to divide 16 to get 4 on each side in which you can use the number for the outer root of the answer. Because 2 and 3 is the only option goes to 6, it is staying under the root in which you will get 4 as your final answer.
Answer:
a. The mean of uniform distribution is (a+b)/2, where a and b are limits of the uniform distribution. So, mean is (0+12)/2 = 6 minutes
b. Standard deviation is (a-b)^2/12 = (0-12)^2/12 = (-12^2)/12 = 144/12 = 12
c. Prob (Wait for more than 5 min) = (12-5)/(12-0) = 7/12 = 0.5833
d. So, given he has waited for 2.8 minutes, what is prob that he will wait between 3.4 and 5.7 minutes
= (5.7 - 3.4) / ((12-2.8) - 0)
= (5.7 - 3.4) / (9.2 - 0)
= 2.3/9.2
= 0.25
e. 10% of all customers wait at least how long for the train?
10% of all customers wait for?
Since its a uniform distribution, people are uniformly spread. So, the 10% of people will be in the top 10% percentile group of waiting time which essentially means:
0.10 = (12-b)/(12-0)
0.10 = (12-b)/12
1.2 = 12 - b
b = 12 - 1.2
b = 10.8 minutes
So, 10% of all customers wait for at least 10.8 minutes for the train.
Answer:
308.65 lb
Step-by-step explanation:
1 lb = 0.45359 kg
140 kg * (1 lb)/(0.45359 kg) = 308.65 lb
1. -3/2
2. -1/2
3. 1.3
4. 1 1/2
