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!

Nethan made eight rose bouquets and six daffodil bouquets. Nethan only has enough flowers to make at most 20 rose or daffodil bo

Igoryamba

I<span> found the graph choices: </span>

<span>Given:</span>
8 rose bouquets
6 daffodil bouquets
total of 14 bouquets

enough flowers left to make maximum of 20 bouquets.

x = additional rose bouquets
y = additional daffodil bouquets

20 maximum bouquets - 14 made bouquets = 6 additional bouquets

x + y = 6

y = 6 - x
x = 6 - y

If x = 0 then y = 6
If x = 6 then y = 0
If x = 4 then y = 2
If x = 2 then y = 4

Pls. see attachment for the correct graph.
