The formula for a cylinder V= pi r squared times the height. I should suppose you were told to abbreviate pi to 3.14. First do 6 to the power of 2 which is 36 then multiply it by 3.14 witch would be 113.04. Then multiply that by 11.5 which would be 1299.96
The answer is 1299.96
Correct Answer:Option A. 0.01
Solution:This is a problem of statistics and uses the concept of normal distributions. We need to convert the score of 90 into z-score and then find the desired probability from standard normal distribution table.
Converting 90 to z-score:

Now we are to find the probability of z score being more than 2.33. From the z-table the probability comes out to be 0.01.
Therefore, we can conclude that the probability of class average is greater than 90 is 0.01.
Step-by-step explanation:
Total books = 368.
Sociology books = 92.
Psychology books = 3 times sociology books
= 3 x 92 = 276
Total = 276 + 92 = 368
Missing Part of Question
Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700
........
Answer:
z = 1.157
Step-by-step explanation:
Given
Annual profit as calculated = $90,300.
H0: μ = 89,000
Ha: μ > 89,000
σ = 8700
n = 60
Calculate the test statistic (z) that corresponds to the sample and hypotheses.
Test statistic (z) is calculated by
z = (x - μ)/(σ/√n)
Where x = 90,300
μ = 89,000
σ = 8700
n = 60
z = (90,300 - 89,000)/(8700/√60)
z = 1.157443298866584
z = 1.157 ----- Approximated
