Suggested Answers (and Discussion) of the Further Maths Exam!

[babushka818]

I got a few different answers

Core.
21. B
24. E

Matrices
8. E because you are calculating Rows not Columns

Geometry
1. A
2. D
3. E
4. A (not 100%)
5. A
6. E
7. C
8. D (not 100%)
[/spoiler]

Same as you for core.
For matrices using rows it was A I thought..

Geometry 8 is right, 4 I am so lost.. It's either A C or E.... Haha

It should be ordinal for 2. It makes sense to order them unlike color or gender

[Rayzorrz]

Matched all for core, matrices and graphs and relations except for Q2. core (got D) and Q5. graphs and relations (got E, which I know now is wrong but am tossing up between B and C).

[blossum]

Bad good excellent is ordinal. Yes or no is nominal

That's.. right.. but.. aw
Heck I can't trust myself
I don't know anymore

Can anyone give me an explanation on Q8 for Core?

[haxor4chan]

This is from Cambridge essential further txtbook....pretty similar to question 2 on exam. Question 5d btw on attached

[brenden]

Note to self - up to date with the discussion.

I'd appreciate it if 2-3 people could tell me what answers to change when it becomes necessary =]

Had no idea idea about the parallel box plot question (I actually eliminated C because I thought it couldn't be categorical) and also got question 2 wrong. Ah well.

Can anyone give me an explanation on Q8 for Core?

Parallel boxplots are used when one variable is categorical and the other is numerical. The variable in the question (monthly median rainfall) is numerical, therefore the other variable has to be categorical. The only categorical option is C.

[hihihi1998]

If you go back to the textbook (Cambridge Further Mathematics Revised) Page 405 it will give you an explanation on how to do the same sort of question, if you use that logic for Q8 of Matrices you will get C.

Regarding Q4 of the Geometry module, I did not select A nor E. With that said, something is telling me it's E because, if you're going based on real times, the sun rises in Portland after Mallacoota. I'm not sure how true this may be to the actual answer so take it with a grain of salt.

Can anyone give me an explanation on Q8 for Core?

Parallel box plots look at association between categorical and numerical variable. All options except C were numerical while C was categorical.

how do you do question 8 from networks?

[powergab]

Can someone please explain why question 7 for matrices is d rather than c!

[jazzaa36]

how do you do question 8 from networks?

You use Hungarian algorithm to find the shortest time allocations which is 2.In this case u can switch Brianna or diedre around hence the answers B ( I THINK LMAO)

[Finnster]

For networks, question 4 although I got E. It can also be C

[Ratish]

Oops, i meant that i got E for question 8 in the networks module. Sorry.
