Sorry, x and y are just real numbers. Such as -12.12, 20, 5080.892, etc.
This is not of the form (a)x + (b)y = (c)x + (d)y
Unfortunately I still don't see what's wrong with the matrix that I typed up. Not that you're wrong, I just can't understand what you're saying because my maths...
Hey everyone. Thanks for so much help on this question.
I need to prove this as part of a broader question in an assignment on utility theory. The equation is this;
aE[u(x)] + (1-a)E[u(y)] = (b+(1-b)a)E[u(x)] + (1-b-(1-b)a)E[u(y)] (1)
Both sides are a gamble, E[u(G(x,y;a))] =...
Hi, thank you for your suggestion. Are you sure that this is a proof? I'm not sure;
[x y] = [x y], hence
[a b] = [c d], hence
a=c,
b=d
I mean it makes complete sense but it's a part of a much longer proof for an assignment so it's important that it's correct
Homework Statement
If;
a*x + b*y = c*x + d*y
x ≠ y
a,b,c,d ≥ 0
Prove that;
a=c
b=d
2. The attempt at a solution
I've been fiddling with this equation and have been getting nowhere.
yes, great point. Thanks!
This is a question on my assignment, and it's worth "5 marks". It is very concerning that a 1-step question would be worth 5 marks? Hmm. Maybe i'll do it your way & the NPV formula way just to scrape marks incase they have some lame marking criteria. I'll also try to...
