Answer:
I think this is the answer you are looking for. (See below)
Step-by-step explanation:
From the given graph it is noticed that the line is passing through many points.
The coordinates of three given points are (1,5), (-1,-1), (-1,-7)
If a line passing through two points (x1 ,y1) and (x2, y2) , the slope of the lie is defined by, m= y2 - y1/x2 - x1
The line passing through two points (-1,1) and (1,5). So the slope of the line is, m= 5 - 1 / 1 minus -1
m=4/2
Therefore, the slope of the line is 2.

Answer:
168 cm.
Step-by-step explanation:
If each book has an equal distance of 12 cm and total books are (20-6) = 14
then, total distance is (12*14) = 168.
I hope this is correct. Feel free to correct me if I'm wrong.
1/5 of 152 is 30.4
1/2 of 152 is 76
1/4 of 152 is 38
hope this helped :)
Answer:
The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Step-by-step explanation:
The least square regression line is used to predict the value of the dependent variable from an independent variable.
The general form of a least square regression line is:
![\hat y=\alpha +\beta x](https://tex.z-dn.net/?f=%5Chat%20y%3D%5Calpha%20%2B%5Cbeta%20x)
Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:
![\hat y=3.73 +0.88 x](https://tex.z-dn.net/?f=%5Chat%20y%3D3.73%20%2B0.88%20x)
Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:
![\hat y=3.73 +0.88 x](https://tex.z-dn.net/?f=%5Chat%20y%3D3.73%20%2B0.88%20x)
![=3.73 +(0.88\times 70)\\=3.73+61.6\\=65.33](https://tex.z-dn.net/?f=%3D3.73%20%2B%280.88%5Ctimes%2070%29%5C%5C%3D3.73%2B61.6%5C%5C%3D65.33)
Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Answer: y=1/3x-2
Step-by-step explanation:
y=Mx+b
1/3 is rise over run
-2 is the y intercept
