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:
Therefore the length of line Segment BC is 20.5 in.
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
∠B = 35°
BC = a
AB = hypotenuse = 25

To Find:
BC = ?
Solution:
In Right Angle Triangle ABC , Using Cosine Identity we get

Substituting we get

Therefore the length of line Segment BC is 20.5 in.
