The walls and ceiling of a storage shed are made of aluminum. the storage shed measures 8 feet wide, 6 feet long, and 5 feet tall. which is the correct unit of measurement to use to figure out the amount of aluminum needed to build the shed?

a. ft

b. ft*2

c. ft*3

ft*3 = volume

ft*2 = area or surface area

ft = perimeter

ft*2=ft*2=area or surface area is the answer

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

answer: y=0 if that is what u r looking for
