Matrices deciding who's best for what job (2010 E1 Q6)

[billyjackson768]

This is always one that annoys me. It's obvious that the two given matrices need to my multiplied which gets rid of all but 2 choices. But deciding the order they need to be multiplied in bugs me. I have had a friend try to explain his reasoning to me a couple of times but he's never been so clear.

This ones getting added to my summary book so any clear and logical explanation as to how you answer this question would be great!

I answered this here: 2010 Matrixes question 6??

Should have looked for that first. Thanks!

So following what you said is I were to answer TU instead I would be giving something with P, F and S for both rows and columns which makes so sense? Or am I confused again because I absolutely don't understand what that matrix would be telling you.
