Calculate the work (in joules) required to pump all of the water out of a full tank. The density of water is 1000 kilograms per cubic meter. Assume the tank

(a) is shaped like an inverted cone of radius 5 meters and height 10 meters where the spout is connected to a 2 meter tube extending vertically above the tank.

(b) is shaped like a horizontal cylinder of radius R and height H where the spout is connected directly to the top of the tank.

sine

step-by-step explanation:

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;

step-by-step explanation:

infinity is the answer
