need help with

2013 Further exam 1, business related maths, question 4 and 7

2018 NHT further exam, matrices, question 8

Thanks

2013 Exam 1
 Question 4 - Price after deposit = 15000-3000=12000
Total amount paid = 36*400 = 14400
Total interest paid = 14400-12000= 2400
Total interest paid per year = 2400/3 = 800
Interest rate per year = (800/1200) * 100 = 6.6667 therefore D

Question 7
As you can see from the graph the annual interest earnt is $50
This is (50/1000) * 100 = 5% per year

Now let the new amount of money invested = x
Amount of money earnt every year = 0.05x.
Therefore Amount of interest earned = x*0.05*8
Solve this for 600 gives us x=1500

I have not done the 2018 NHT exam and want to leave it till last so I will let someone else answer that question

You could at least include the questions so we don't have to go looking for them ourselves...

PSA to all:
If you're somebody who answers questions in this thread, please encourage them to have a go at it themselves and provide their current working out/understanding as well, as it identifies their misconceptions and gaps in understanding. Doing the q for them may help with that particular question but isn't the best way to addressing the skill.

[Lear]

and an attempt/your current understanding

You'd hate to see the methods question thread :')

mate, I am well aware It was and continues to be one of my key frustrations both as a former natmod on AN and a teacher.

Spoonfeeding them the answer may help with getting the answer to that particular question, but if they just repeat the same flaw over and over in future questions have they really learnt? Could argue they will learn based on your worked solution which may be true, but in most cases it'll just get repeated later on.

Pleeeasseeee people, if you ask a question.... give us something more than just the actual question!! It will benefit you in the long run.

As someone who throughout the year has consistently contributed to that thread it has become a turn off for me very recently too. Perhaps some rule changes may be necessary such as showing some sort of working out or attempt at the question.

2018 NHT further exam, matrices, question 8

Thanks

2018 NHT Exam 1 question 8
1) put the objective function 5x+2y=1 on a graph page, which gave me the co-ordinates (0,5) and (2,0)
2) then plot these on each graph and drew a line between them
3) on each graph, slide the line up to each point P, if that Point P is the first and only point you hit, then that is the minimum value

In the end i got E, which is correct

Hope this helps!

Hi, so the question below is from the 2017 NEAP trial exam.
I answered, B, but according to the answers, D is correct. Why is B incorrect, as (450000-20000)/100000 = 4.3?
Thanks!

[KiNSKi01]

Well that's kinda stupid 

I'm guessing the reason they have chosen D as answer over B is that you can only have a whole number of X-rays. Seems kinda ridiculous to me since B and D are mathematically equivalent

Hey guys,
Can a dummy be counted as a predecessor? (Networks)

Nope. It isn’t actually an activity. It would whatever the dummy is linking from that are the predecessors

Extremely odd question but does anyone know if we are allowed to write ON our bound references during the exam?

Extremely odd question but does anyone know if we are allowed to write ON our bound references during the exam?

The exam- navigator doesn't really say anything but: "If any page or part of a page is detached from the rest of the
bound reference, the page will be removed by the supervisor for the duration of the examination and the incident will be reported as
a potential breach of rules"

If your using it to work things out, maybe try writing at the back of the formula sheet which i think is given seperate to the exam

[Lear]

Thanks!
Don’t plan to use it for working out but rather have a premade checklist with common mistakes  at the back to tick off when I’ve finished my exam.

If you're worried about it just ask when you walk in, they'll tell you.

If they don’t want you writing in it then number the checklist and then write the numbers on your sheet and tick them off on there instead. I really doubt that it’d be an issue though.
