Answer:
V = 1200π
Step-by-step explanation:
Volume of a cylinder formula:
Let's find the height of the cylinder by multiplying 20 cm by 3/5.
The radius is 1/2 of the diameter, so:
Substitute 12 for h and 10 for r into the volume formula.
Simplify.
- V = π * 100(12)
- V = π * 1200
The volume of a cylinder, in terms of π, is V = 1200π.
M+(m+15)=55
2m+15=55 (subtract 15)
2m=40 (divide by 2)
m=20

Answer:
Probability that the sample variance exceeds 3.10 is less than 0.05%.
Step-by-step explanation:
We are given that a process produces batches of a chemical whose impurity concentrations follow a normal distribution with a variance of 1.75.
Also, a random sample of 20 of these batches is chosen.
The probability distribution that we will used here is of Chi-square distribution, i.e.;
~
where, = sample variance
= population variance = 1.75
n = sample of batches = 20
So, probability that the sample variance exceeds 3.10 is given by = P( > 3.10)
P( > 3.10) = P( > )
= P( > 59.62) = P( > 59.62) = Less than 0.05%
From chi-square table we can observe that Probability that is greater than is less than 0.05%.
So, the probability that the sample variance exceeds 3.10 is less than 0.05%.
