A small independent organic food store offers a variety of specialty coffees. To determine whether price has an impact on sales,
lorasvet [3.4K]

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!

Find the area of this figure (50 points)
Softa [21]

Answer:

A_{total} = 14\ in^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the left rectangle</u>

We can tell that the total shape seems like two rectangles glued together.  We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them.  Lets first solve the left rectangle.

A = l * w

A_{left\ rectangle} = 2\ in * 4\ in

A_{left\ rectangle}  = 8\ in^2

<u>Step 2:  Determine the area of the right rectangle</u>

A = l * w

A_{right\ rectangle} = 3\ in * 2\ in

A_{right\ rectangle} = 6\ in^2

<u>Step 3:  Determine the total area</u>

A_{total}=A_{left\ rectangle} + A_{right\ rectangle}

A_{total} =  8\ in^2 +  6\ in^2

A_{total} = 14\ in^2

Answer: A_{total} = 14\ in^2
