Len [333]

Answer: 3

Step-by-step explanation:

Given : Standard deviation : \sigma=4.1\text{ seats}

Margin of error : E=\pm5\text{ seats}

Significance level : \alpha: 1-0.95=0.05

By using the standard normal table of z ,

Critical value : z_{\alpha/2}=1.96

The formula we use to find the minimum sample size required :-

n=(\dfrac{z_{\alpha/2}\ \sigma}{E})^2

i.e. n=(\dfrac{(1.96)(4.1)}{5})^2=2.58309184\approx3

Hence, the number of lights should we select if we wish to estimate μ to within 5 seats and be 95 percent confident =3

A cone has a diameter of 3 inches. The cone holds 12 cubic inches of water.
dmitriy555 [2]

Answer:

The  height of the cone is 5.09 inches

Step-by-step explanation:

Given:

The volume of the cone  =  12 cubic inches

The diameter of the cone  = 3 inches

To Find :

The height of the cone  =  ?

Solution:

We know that the volume of the cone is

Volume  = \pi r^2\frac{h}{3}

where

r is the radius of the cone

h is the  height of the cone

Now substituting the given values

12 = \pi (1.5)^2  \frac{ h }{3}

\frac{12}{\pi 2.25}  = \frac{h}{3}

h = \frac{12}{ 2.25 \pi} \times 3

h = \frac{ 12}{7.065} \times 3

h = 1.698 \times 3

h =  5.09  inches
