VCE Further Maths Exam 2 Discussion and Solutions

[accoleg]

That's exactly what I was going to ask! For the Hung Algo I said that Colin must be allocated to Tour 2, and for the new minimum time I did 17 days and minimum cost I did $4000 for the crashing question. That was hard!

I got the same for the Hungarian! Somehow I only got a reduction by 1 from the original minimum completion time, and $2000 for the crashing q, waiting for a copy of the exam to check!

Can someone please confirm for me the answer for the last Business question= $805.65?

got that too

I did that and my friend did that as well. Phew.

I'm not sure about the crashing lmao but I reduced L first, giving reduction of one day, then I reduced I, J, and G, which were on the only three different critical paths, reducing another day.

2 Mark matrices question: 25%
2 Mark recursion question: $805.65 or something like that
2 mark graphs question: $220
Last graphs question: 9 & 3
Graphs and relation intersection of 2 graphs: 10.98 minutes

Any other questions feel free to ask.

Whats this I hear about the matrix L question. What could it be besides [ 0 1 1 ]?

For the 2 mark matrices question, I think I got 30% of the senior students who were expected to do Investigation in term 3 and was expected in Service in term 2? It was similar to a question on 2016 VCAA exam 2.

How did everyone do on the last couple of questions on the networks module? There were a couple of weird questions in there in my opinion, particularly the quesition about what the "0" in the Hungarian Algorithim meant? And what did everyone get for the max time  and min cost reduction on the crashing question?

The 0 indicates that the person from that column has to do task 2 because there were no other 0 in that column, or that's what I put?

Any other questions feel free to ask.

You sure it wasn't 11.11 minutes?

Edit: omg i put y=-62.5x+1125 and y=50x into my CAS instead of 40... yeah it's 10.98. 

[em_gugel]

I got 11 minutes for the graphs and relations question after putting it in my CAS

I got [0 1 1] too

[superficious]

I got 11 minutes for the graphs and relations question after putting it in my CAS 

I got 11 too so..

[addictwithatextbook]

what did u guys do for that  total question for matrices?

Vague question but I did 750 junior students, or L = [0 1 1], or some other answer to the question you're asking?

[dx1sy]

I got 11 too so..

I got 10.98
It asked for the minutes to two decimal places, so it can't be 11 minutes.

For the last question in Business, i think, was the equation
Ao=428, An+1=1.00125an
