so the line looks more or less like that, with Y splitting XZ on a 3:11 ratio.
that simply means, that XZ is split on 3+11 pieces, and XY is taking up 3 of those pieces.

Hopes this helps:
Answer: x = -2, -2/3
If it wrong I am sorry
The standard error of the mean is 128.125.
The formula for standard error is:

With our information, we have:
Answer:
Step-by-step explanation:
What variable are you solving for?
-4x+y=29
y=29-(-4x)
y=29+4x
y=4x+29
----------------
-4x=29-y
-4x=-y+29
x=1/4y+29/-4
y=1/4y-29/4
-3 is in the opposite direction of V
