Answer:

Step-by-step explanation:
The equation for the least-squares regression is,

where b is the slope and a is the intercept.
They can be found out by,

where,
r = correlation coefficient = 0.84
 = standard deviation of y = 44,910
 = standard deviation of x = 28,803
 = mean of y = 774,140
 = mean of x = 354,718
Putting the values,


Therefore the equation is,

 
        
             
        
        
        
Answer:
y=-4x-4
Step-by-step explanation:
y=-4x-4
y=mx+b where m=slope and b=y-intercept.
 
        
             
        
        
        
The answer is c, because it is the same line, just higher.
        
             
        
        
        
Group 1:-
5 cookies
3 people
5/3
Group 2:
8 cookies
6 people
8/6
Group 1 each person gets 5/3 and in group 2 each person gets 8/6.
Which is more?
5/3
5 ÷ 3 ≈ 1.6
8/6
8 ÷ 6 ≈ 1.3
Is 1.3 more or 1.6?
1.6 is more.
5/3 (group 1) receive more.
