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!
Alright here's the breakdown:
it said every 4 miles <span>Vanessa jogged, Cody jogged 3 miles.
so
</span><span>Vanessa jogged 1 mile
that means
Cody jogged .75 of a mile ( or 75% of 1 )
because
Cody will always jog 75% of how much Vanessa joged
so say that
</span><span>Vanessa jogged 50 miles
all you do is take 75% of how much </span>Vanessa jogged
and that should be how much Cody joged
hopes this helps!
It is C (2, 1) I think it is because they intersect
He mails
(1000) x (the number of weeks he keeps it up)
of them.
