i have a function [tex]y=f(x)[/tex] with three points;
[tex]A (1, 40)[/tex]
[tex]B (3, 80)[/tex]
[tex]C (5, 90)[/tex]
the [tex]x[/tex] model represents days. and the [tex]y[/tex] model represents failed parts on an assembly line.
the question is: how many failed parts will have been identified [tex]1[/tex] week from now?
I have no problem with doing the work, getting the slopes, figuring out all the algebraic gymnastics and getting the equations.
heres what i have:
[tex]A\rightarrow B, y=20x-20[/tex]
[tex]A\rightarrow C, y=\frac{25}{2}x+\frac{55}{2}[/tex]
[tex]B\rightarrow C, y=\frac{77}{5}x+26[/tex]
I actually think my equation from [tex]B\rightarrow C [/tex] could be incorrect.
now, the part that is getting me is I am trying to get the residual? i need to get some medication because my ADHD is seriously out of control. its getting worse as i get older.
i need to construct some table... this is what i have for the first one:
real obverved measures residual
[tex]x,... y,... y_{1}=20x-20,... (y-y_{1})^2[/tex]
[tex]1,... 40, ...40, .....0[/tex]
[tex]3,... 80, ...80, .....0[/tex]
[tex]5,... 90, ...120, ...900[/tex]
real obverved measures residual
[tex]x,... y,... y_{2}=\frac{25}{2}x+\frac{55}{2},... (y-y_{1})^2[/tex]
[tex]1,[/tex]
[tex]2,[/tex]
[tex]3,[/tex]
not quite sure how to do all of this. :(
