Hello!

The slope is $\frac{rise}{run}$ . One way we could do this is find two points on the line and form a right triangle to connect the two. We then divide the rise of this triangle by the run.

We can see the points (-3,-2) and (0,-1). As you can see, our rise is 1, and the run is 3. If we divide our rise by run, we get the slope of 1/3.
------------------------------------------------------------
The work we did above can be represented in the following formula.

$\frac{ y_{2} - y_{1} }{ x_{2}- x_{1} }$

The ones and twos just represent a certain ordered pair. We will have (0,-1) be ( $x_{1} , y_{1}$ ) and (-3,-2) be ( $x_{2} , y_{2}$ ). Now we plug our numbers into the formula. Note that the ones and twos can be swapped and the slope will be the same.

$\frac{-2+1}{-3-0} = \frac{-1}{-3} = \frac{1}{3}$

This proves that our slope is 1/3.

I hope this helps!

DanielleElmas [232]

Yes, Luis is correct.
If s is equal to the the side length, then in the problem, s is equal to 8 millimeters. 8 x 3 is equal to 24, which would equate to 24 cubic millimeters.

The reciprocal of 6 4/5 is

It should be 34/5*. If you create an improper fraction out of the original one, then creating the reciprocal will be easier.

$a^2+b*2=c^2$

$a^2+2b=c^2

$ $\text{Regroup terms}$

$a^2=c^2-2b
$ $\text{Subtract 2b from both sides}$

$a=\pm \sqrt{c^2-2b}$ $\text{Take the square root of both sides}$

Answer:

1. The population of interest is all city goverments in the U.S.

5. The parameter of interest is the proportion of the city goverments in the U.S. that provide electricity to their residents.

Step-by-step explanation:

Hello!

Missing questions:

Which of the following is true? Select all that apply.

The population of interest is all city governments in the U.S.
The population of interest is the 192 cities.
The population of interest is all city governments that provide utilities to their residents.
The population of interest is 6.25%
The parameter of interest is the proportion of the city governments in the U.S. that provide electricity to their residents.
The parameter of interest is 6.25%
The population of interest is the 20 counties.
The parameter of interest is the list of all counties in the U.S.

The objective of this essay is to test utilities provided by city governments, for this a sample of 20 counties was taken then contacted each city of them counting how many of them provided utilities to their residents, finding out that 12 out of 192 cities (6.25%) provided electricity to their residents.

The study variable is:

X: Number of city governments that provide utilities (electricity) to their residents, in a sample of 192.

The population of the study is the city governments in the U.S.

And the parameter of interest is the population proportion of city governments in the U.S. that provide electricity to their residents.

I hope it helps!
