Answer:
I think the answer is the fourth one
Step-by-step explanation:
Area = 2pi*r*h + 2pi*r^2
Area = 2pi*r(h + r)
radius of 7 in and a height of 32 in
Area = 14pi*39 = 546pi in^2
Answer:
b) equals 20 hours.
Step-by-step explanation:
The sampling distribution of means refers to the distribution of all the possible sample means, with a certain sample size (in this case, n=100) extracted from the population.
The sampling distribution of the means is equal to the population mean. That does not mean that every sample will result in a mean equal to the population, but that the population of sample means will have an average of 20 hours.
