Answer:

113.1 cubic inches

Step-by-step explanation:

The volume of a cylinder is given by the formula:

$V=\pi r^2 h$

Where

V is the volume

r is the radius

h is the height

Given, h = 9 and r = 2, we substitute and find the volume:

$V=\pi r^2 h\\V=\pi (2)^2 (9)\\V=36\pi\\V=113.097$

We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:

113.1 cubic inches

According to the Current Population Report of the United States census, 26.7% of people aged 65 and older have earned a bachelor

rodikova [14]

Answer:

At least 585 people aged 65 and older is needed to be surveyed for the 90% confidence level and 3% margin of error.

Step-by-step explanation:

The following formula can be used to compute the minimum sample size required to estimate the population proportion within the required margin of error:

n≥ p×(1-p) × $(\frac{z}{ME} )^2$ where

n is the sample size

p is the proportion of people aged 65 and older have earned a bachelor's degree or higher (26.7% or 0.267)

z is the corresponding z-score for 90% confidence level (1.64)

ME is the expected margin of error in the estimation (0.03)

then n≥ 0.267×0.733 × $(\frac{1.64}{0.03} )^2$ ≈584.87

Then n should be at least 585

What is the average score of runa 140,96 and 13?

scoundrel [369]

$\huge\textsf{Hey there!}$

$\large\textsf{Formula:}$

$\mathsf{\dfrac{Sum\ of\ all\ terms}{Total\ number\ of\ values\ in\ the\ data}= your\ mean/average}$

$\mathsf{\dfrac{140+96+13}{3}}$

$\mathsf{140+36+13}$

$\mathsf{140 + 96 = \bf 236}$

$\mathsf{236 + 13}$

$\mathsf{ = \bf 249}$

$\mathsf{\dfrac{249}{3}}$

$\mathsf{= \bf 83}$

$\boxed{\boxed{\large\textsf{Possible answer: \huge \bf 83}}}\huge\checkmark$

What is the difference of (3/4x-2/3)-(-5/6-2x)

Alex Ar [27]

This equation is also equal to 3/4x - 2/3 + 5/6 + 2x since subtracting a negative is the same as adding a positive in the long run. First, simplify the variables to get 2 3/4x - 2/3 + 5/6. -2/3 is also equal to -4/6, so -4/6 + 5/6 is 1/6. The simplified version of this expression is 2 3/4x + 1/6. Hope this helps!
