The formula for the volume of a sphere is v= 4/3 3.14rWhat is the formula solved for r?
prohojiy [21]

Answer:

r = \frac{3}{4\pi}V

Step-by-step explanation:

First, the formula for the volume of a sphere is:

V = \frac{4}{3}\pi r^3

\frac{3}{4}V = \pi r^3

\frac{3}{4}V\frac{1}{\pi} = r^3

r^3 = \frac{3}{4\pi}V

r = \sqrt[\leftroot{-2}\uproot{2}3]{\frac{3}{4\pi}V}

A Gallup Poll in July 2015 found that 26% of the 675 coffee drinkers in the sample said they were addicted to coffee. Gallup ann
emmasim [6.3K]

Answer:

The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

A confidence interval has two bounds, the lower and the upper

Lower bound:

\pi - M

Upper bound:

\pi + M

In this problem, we have that:

\pi = 0.26, M = 0.05

Lower bound:

\pi - M = 0.26 - 0.05 = 0.21

Upper bound:

\pi + M = 0.26 + 0.05 = 0.31

The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.
