Answer:
6394
Step-by-step explanation:
WXYZ
X < Z
Z = ⅔W
W = ⅔Y
Y = 3X
W = ⅔(3X) = 2X
Z = ⅔(2X) = (4/3)X
X has to be a multiple of 3
If X = 3,
Y = 9
Z = 4
W = 6
WXYZ
6394
If you're looking for the equation, the answer is y=2x-3
Answer:
II. The sum of the residuals is always 0.
Step-by-step explanation:
A least squares regression line is a standard technique in regression analysis used to make the vertical distance obtained from the data points running to the regression line to become very minimal or as small as possible.
For any least-squares regression line, the sum of the residuals is always zero.
Basically, residuals are used to measure or determine whether or not the line of regression is a good fit or match for the data by subtracting the difference between them i.e the predicted y value and the actual y value, for the x value respectively.
Hence, the statement about residuals which is true for the least-squares regression line is that the sum of the residuals is always zero (0).

I dont either tbh
Answer:
x = 12
Step-by-step explanation:
To solve this and show your work, you have to start of with the equation (3x - 6) = 30.
You then have to add 6 to both sides like this:
So then the 6 is cancelled out, and you are left with
3x = 36.
Now you just have to divide both sides by 3 like this:
Which cancels 3 out, and you are left with
x = 12.
