8×12=96. Katie 
12×12=144. Mary 
you have to Divide Katie's 96 by 8 to get 12 
then take Mary's 12 and multiply it by 12 to get the answer of 144 apps that Mary owns 
        
             
        
        
        
Answer:
206,762
Step-by-step explanation:
206,000 * 0.037 = 762.2
762.2 + 206,000 = 206,762.2, rounded to 206762
 
        
             
        
        
        
<span>Linear regression is a method of finding the linear equation that comes closest to fitting a collection of data points.
</span>The better the choice of line, the closer the predicted values will be to the observed values. 
The differences between the data pints (observed values) and the estimated (pedicted) regression line is called  the <span>residue.
</span>Residue = Observed Value -<span> Predicted Value</span>
        
             
        
        
        
Ans(1):
Given equation is f(x)=-1.5x+6 
we can plug any number like x=0 and x=2 to find the f(x) also called y-value
plug x=0
f(x)=-1.5x+6 =-1.5*0+6 =0+6 =6
Hence first point is (0,6)
plug x=2
f(x)=-1.5x+6 =-1.5*2+6 =-3+6 =3
Hence first point is (2,3)
now we can graph both points then join them to get final graph of f(x)=-1.5x+6 
---------------------
Ans(2):
We can repeat exactly same process for f(x) = -1/2x-5.
So the final graph will look like attached picture:
