Answer:
Correct answer is :
To simplify and summarize data
Step-by-step explanation:
Using sample data we can make inferences about a population using statistical methods such as linear regression. But descriptive statistics, as only describe general characteristics of a sample, can be not generalized to a larger population only by descriptive statistics.
Descriptive statistics (DS) can be used to describe dependent or dependent variables alike. If for example you want to predict the income of a person (dependent) in relation to age, education level ( independent) , descriptive statistics may be used to describe both type of variables the age of the sample or the levels of income.
DS are used basically to summarize data or to make it more simple to analyze.

Step-by-step explanation:
Depending on the variables give in the scatterplot you may get one of the above answers
Answer:
45
Step-by-step explanation:
19+26 fences equal 45
To solve this equality we are going to use
the <span>
division property of equality, which says that you can divide both sides of the equality by the same number; notice that the number in question cannot be zero since you cannot divide by zero. In our case we are going to divide both sides by 4.5 to get rid of the 4.5 that is multiplying </span>

:
![4.5x=18](https://tex.z-dn.net/?f=4.5x%3D18)
![\frac{4.5x}{4.5} = \frac{18}{4.5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4.5x%7D%7B4.5%7D%20%3D%20%5Cfrac%7B18%7D%7B4.5%7D%20)
![x= \frac{18}{4.5}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B18%7D%7B4.5%7D%20)
Answer:
y = ![-\frac{4x-5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B4x-5%7D%7B2%7D)
Step-by-step explanation:
Step 1: Switch sides
5 - 2y = 4x
Step 2: Subtract 5 from both sides
5 - 2y - 5 = 4x - 5
Step 3: Simplify
-2y = 4x - 5
Step 4: Divide both sides by -2
![\frac{-2y}{-2} = \frac{4x}{-2} - \frac{5}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2y%7D%7B-2%7D%20%3D%20%5Cfrac%7B4x%7D%7B-2%7D%20-%20%5Cfrac%7B5%7D%7B-2%7D)
Step 5: Simplify
y = ![-\frac{4x-5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B4x-5%7D%7B2%7D)
