Answer:

Step-by-step explanation:

Firstly you could expand the indices

This would give you

5 x 5 x 5

This is because 5² is equivalent to 5 x 5

5 x 5 x 5 =125

But we have to give the answer in index form

This means the answer is 5 cubed or 5³

andriy [413]

7n-22 ≥ 64

1. Move constant to the right.

7n ≥ 64 + 22

2. Combine like terms.

7n ≥ 86

3. Divide 7n by 7 to get n alone.

n ≥ 86

4. Divide 86 by 7.

n ≥ 86 / 7 OR n ≥ 12.29

Norm must pay to have trash collected he can put out 1 barrel of trash per week a rectangler container measure 32 inches by 18 i

Ainat [17]

Answer:

The Cycling Rick container can hold more trash.

Step-by-step explanation:

The rectangular container is basically a rectangular prism, so to find its volume, we are using the formula for the volume of a rectangular prism:

$V=whl$

where

$V$ is the volume

$w$ is the width

$h$ is the height

$l$ is the length

We know that the rectangular container is 32 inches by 18 inches by 10 inches, so $l=32in$ , $w=18in$ , and $h=10in$ . Let's replace the values in our formula:

$V=whl$

$V=(18in)(10in)(32in)$

$V=5760in^3$

The rectangular container can hold 5760 cubic inches of trash.

Now, the Cycling Rick container is basically a cylinder, so to find its volume, we are suing the formula for the volume of a cylinder:

$V=\pi r^2h$

where

$V$ is the volume

$r$ is the radius

$h$ is the height

We know that the its height is 30 inches, so $h=30in$ . Since the container is 20 inches wide, its diameter is 20 inches, and since the radius is half the diameter, $r=\frac{20in}{2} =10in$ . Let's replace the values:

$V=\pi r^2h$

$V=\pi (10in)^2(30in)$

$V=9424.78in^3$

The Cycling Rick container can hold 9424.78 cubic inches of trash.

Since 9424.78 cubic inches is bigger than 5760 cubic inches, we can conclude that the Cycling Rick container can hold more trash.

Make a decision about the given claim. use only the rare event? rule, and make subjective estimates to determine whether events

Elan Coil [88]

Given claim: A coin favors heads when tossed, and there are 90 heads in 100 tosses.

Answer: There isn’t sufficient evidence to support this claim, because the coin is a fair coin.

Given claim: Movie patrons have IQ scores with a standard deviation that is less than the standard deviation of 15 for the general population. A simple random sample of 40 movie patrons result in IQ scores with a standard deviation of 14.8.

Answer: Claim is either true or false

In a rare event rule, <span>we conclude that the assumption is probably not correct, if, under a given assumption, the probability of a particular observed event is exceptionally small. </span>
