Answer:
b= -4.68
Step-by-step explanation:
Hello!
We have to study variables:
Y: Monthly coffe sales
X: Price per pound of coffe ($)
The estimate regression line is
^Yi= a + bxi ∀ (i=1,.....,10)
The slope of the estimated regression line is represented by b.
The formula I'll use to calculate it is:
b= [n∑xiyi -(∑xi)*(∑yi)]/ n∑xi²-(∑xi)²
To calculate b we need to do some auxiliary calculations:
∑xiyi= 4213.15
∑xi= 87.47
∑yi= 545
∑xi²= 883.3703
Then we replace the formula:
b= [10*4213.15-(87.47)*(545)]/ n883.3703-(87.47)²
b= -4.68
I hope you have a SUPER day!

Answer:- The composition of translation is :
Translation: (x,y)→(x-2,y+2) [as the given piece moved 2 steps to the left and 2 steps upwards]
Translation:(x,y)→(x+2,y+2) [as the given piece moved 2 steps to the right and 2 steps upwards]
A single translation that moves the piece from its original position to its ending position is [ignoring the diagonal movement]
Translation:-(x,y)→(x,y-4)[as piece have to go 4 steps downwards]
