Answer:
Step-by-step explanation: This is a question under linear regression analysis.
The question is trying to relate sales (in $1000) and and advertising.
Both sales and advertising are variables and are connected by the equation
Y = 32x + 8
Which is a linear regression equation of 2 variables.
Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.
At $1 of adverts, we have $40 of sales.
We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)
Y = 32(1) + 8
Y = 32 + 8
Y = $40.
Answer:
(p-q)(1+x)
Step-by-step explanation:
p-q-x(q-p)
p-q-xq+xp
p+xp-q-xq
p(1+x)-q(1+x)
(p-q)(1+x)
Answer:
a = 156
Step-by-step explanation:
24 and a form a straight line so they add to 180 degrees
24 +a = 180
Subtract 24 from each side
24+a-24 = 180-24
a = 156
