Answer:

V = 48π

Step-by-step explanation:

$V=\pi r^{2} \frac{h}{3}$ Use the equation to find the volume of a cone

$V = \pi (4)^{2} \frac{9}{3}$ Simplify the exponent

V = π(16) $\frac{9}{3}$ Multiply

V = 48π

vodka [1.7K]

Answer:

The answer is "294.2075".

Step-by-step explanation:

Given:

$\hat{p} = 0.5 \\\\1 - \hat{p} = 1 - 0.5 = 0.5\\\\E = 4\% = 0.04\\\\$

At $83\%$ confidence level the z is ,

$\alpha = 1 - 83\% = 1 - 0.83 = 0.17\\\\\frac{\alpha}{2} = \frac{0.17}{2} = 0.085\\\\Z_{\frac{\alpha}{2}} = Z_{0.085} = 1.3722\\\\n = (\frac{Z_{\frac{\alpha}{2}}}{E})^2 \times \hat{p} \times (1 - \hat{p})\\\\$

$= (\frac{1.3722}{0.04})^2 \times 0.5 \times 0.5\\\\= (34.305)^2 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.25\\\\=294.2075$

If f (x)=8-5x, find the value of f(2-k)

Helen [10]

Hello from MrBillDoesMath!

Answer:

f(2-k) = -2 + 5k

Discussion:

If f(x) = 8 - 5x , then

f(2-k) = 8 - 5(2-k) =>

f(2-k) = 8 - 10 + 5k =>

f(2-k) = -2 + 5k

Plot of land between two roads are laid out according to the boundaries shown. The boundaries between the two roads are parallel

FinnZ [79.3K]

Given:
Cheshire Road Shelby Road
Plot 1 40 yards 48 yards
Plot 3 x 56 yards

To solve for x, we get the ratio and proportion of both plots.

40/48 = x/56

Do cross multiplication.

40 * 56 = 48 * x
2,240 = 48x
2,240/48 = 48x/48
46.67 = x

Plot 3 of Chesire Road measures 46.67 or 46 2/3 yards. Choice A.
