Answer:
the equation of the least-squares line for the data is: 
Step-by-step explanation:
In a simple linear regression model, such as,
, the coefficients bo and b1 are estimated through the method of least squares by the use of the equations:

For the data provided you have to:
, thus:

the equation of the least-squares line for the data is:

Answer:
The equation of the line in the slope-intercept form is:
Step-by-step explanation:
The slope-intercept form of the equation of a line is

As y intercept is -8, we have

Since the line is parallel to
, then it has the same slope.
Let's put this equation in
form and find the slope


Thus, the slope is :

Now we can finish the equation of the line in the slope-intercept form

∵
, b = -8
Therefore, the equation of the line in the slope-intercept form is:
Answer:
(3x2 + x + 4) • (x - 1)
————————————
x - 3
Step-by-step explanation:
Answer: 5cups of flour = 1 loaf of bread
45 loaves of bread multiplied by 5 cups of four = 225 cups of flour to make 45 loaves of bread.
225 cups of flour divided by 4 = 56.25 pounds of flour.
