ypu man i realyl do ..coz i messed up the algorithm part ..so like 8 marks and then the last part of simulation ..that was..hmm 2 marks..and ......hmmm...the 2 maker for graphs ..wth was the graph question part 2 ???!!

It was asking you to draw a graph, and then treat the regions of the graph like a new map and then draw the graph of this new map, if that makes sense

It said it was planar, so four vertices, all connected to every other verticex, with none of the lines crossing. That's what I put anyway, I'm not sure it's right

Yeah, I think so, I can't remember too great though

This was the hardest paper I've tried, I've never been so stressed in an exam

It took me so long to understand the algorithm, haha I think I got the swaps and comparisons numbers wrong :/ I liked the LP, CPA and simulations. I love cascade diagrams idk why.. ! anyway I know I didn't do that well but I'm confident with c1 and c2 so hopefully this grade won't bring down my overall AS maths grade hahah :/

does this look right for the lp question

looks about right, assuming Y is skis and X is snowboards, but the line for y > 1.1x looks off to me, when there are 200 snowboards (x) there should be >200 skis, and at the moment when there are 200 snowboards there are <200 skis

same as above, you've drawn the line 11y>10x, the coefficients should be the other way around.

no i done it wrong, i did 1.1y>x

I'd very much appreciate it if you could upload a scan of it so I can check my answers

11y>10x is the same as 1.1y>x

I'm fairly sure. You've taken y to be skis, and there should be more skis than snowboards at any point on that line, but the opposite is true for your graph.
