Answer:
hello your question is incomplete attached below is the missing data
answer : Y = 206.0859 - 1.3191 X
Step-by-step explanation:
Determine the regression equation using the data on revenue and distance
The regression line equation is written as :
Y = 206.0859 - 1.3191 X
applying the regression equation to data given to determine the value of Y and residual value
First of all to make our equation simpler, we'll equal
to a variable like 'a'.
So,
Now let's plug
's value (a) into the equation.
Now we turned our equation into a quadratic equation.
(The variable 'a' will have a solution set of two solutions, but 'x' , which is the variable of our first equation will have a solution set of four solutions since it is a quartic equation (<span>fourth-degree <span>equation) )
Let's solve for a.
The formula used to solve quadratic equations ;
The formula is used in an equation formed like this :
</span></span>
In our equation,
t=16 , b=-41 and c=25
Let's plug the values in the formula to solve.
So the solution set :
We found a's value.
Remember,
So after we found a's solution set, that means.
and
We'll also solve this equations to find x's solution set :)
So the values x has are :
,
,
and
Solution set :
I hope this was clear enough. If not please ask :)

It's B. Because of the line is not going up or down, so the slope should be 0. And the line is 3 block above the 0 point, so y-inter is 3.
Answer:
ans: x=12 nd 4x= 48
Step-by-step explanation:
so since ratio is 1:4 we take 1x+4x=5x=60
x=60/5=12
1x=12
4x=12*4=48
hope this helped!
