<h2>Answer</h2>

92 m³

<h2>Explanation</h2>

First we are going to find the volumes of the sphere and cone separately; then, we'll subtract the volume of the cone from the volume of the sphere.

Volume of the sphere:

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

where

V is the volume of the sphere

r is the radius

We can infer from our picture that r = 3 m, so let's replace the value

V=\frac{4}{3} (3.14) (3m)^3

V=\frac{4}{3} (3.14) (27m^3)

V=113.04m^3

Volume of the cone:

V=\pi r^2\frac{h}{3}

where

V is the volume of the cone

r is the radius  

h is the height

We can infer from our picture that r = 2 m and h = 5 m, so let's replace the values

V=(3.14)(2m)^2\frac{5m}{3}

V=(3.14)(4m^2)\frac{5m}{3}

V=20.93m^3

Volume of the shaded area = volume of the sphere - volume of the cone

Volume of the shaded area = 113.04m^3-20.93m^3=92.11m^3

And rounded to the nearest integer:

Volume of the shaded area = 92m^3

An insurance company estimates 45 percent of its claims have errors. The insurance company wants to estimate with 99 percent con
nydimaria [60]

Answer:

We need a sample size of at least 657.

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 given by:

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

45 percent of its claims have errors.

So \pi = 0.45

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

What sample size is needed if they wish to be within 5 percent of the actual

This is a sample size of at least n, in which n is found when M = 0.05.

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

0.05 = 2.575\sqrt{\frac{0.45*0.55}{n}}

0.05\sqrt{n} = 1.28

\sqrt{n} = \frac{1.28}{0.05}

\sqrt{n} = 25.62

\sqrt{n}^{2} = (25.62)^{2}

n = 656.4

We need a sample size of at least 657.

Answer:

2 and 5 for sure. I think 4 is correct, but your teacher may not.

Step-by-step explanation:

The given expression reduces down to -7m - 8 = m - 4

1 cannot give -15m on the right. One seldom sees that mistake on Brainly.

3 does not do that. - 3m is not - 7m

4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.

5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m

6 has been reduced on the left incorrectly. the right is it's signs backwards

2 4(?) and 5
