Answer:
You have the formula wrong.
The volume of a cylinder = PI * radius^2 * height
To find the height, the formula is:
height = volume / (PI*radius^2)
I'm assuming the radius = .6 meters so
height = 720 / (3.14159265 * .6^2)
height = 720 / 1.130973354
height = 636.61977 meters

The Solution:
Given:
Required:
Find the standard deviation of the probability distribution.
Step 1:
Find the expected value of the probability distribution.


Step 2:
Find the standard deviation.




Thus, the standard deviation is 1.60
Answer:
1.60
<span>The probability she failed the interview is: 1 - probability she passed the interview.
P( failed 1st interview) = 1 - 0.9 = 0.1
P(failed 2nd interview) = 1 - 0.8 = 0.2.
P(failed 3rd interview) = 1 - 0.7 = 0.3
So we have that if she didn't get the job, the probability that she failed the second interview is 0.2</span>
