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 correct option is a.
Step-by-step explanation:
It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.
<u>EMI on $1000 is $8.78, so EMI on $1 is</u>
EMI on $1 = 8.78/1000 = 0.00878
<u>EMI on $50150 is</u>
<u>EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32</u>
Therefore the correct option is a.
Hope this help you! ^_^
