Is it a good idea to buy the ExamPro Further Maths book? Seems like it's for the old study design  :-[

I can't remember how much the study design changed but I'd be a bit wary of getting it. It may be useful for just doing practice questions but I wouldn't count on it as being a substitute for past VCAA exams (as I'm not sure if the format is different in the exampro book). I'd probably only get it second hand, I don't think it's worth buying new as there are probably better options out there.

Why is using deseasonalisation on a graph not as accurate as using the moving mean average? Thanks!

Look at the attachment to know what I'm talking about.
How would you make this into a network?

Would you have an edge linking e.g Mr.J to Mr.W to Mrs Martinez  and all these teachers that are in a horizontal line. OR would you jst have an edge connecting Mr Smith and Mr W and then have 4 edges from Mr Ryan linking to all the teachers in that one line.

I don;t know if any of that makes sense. But thanks!

Hey fam,
Silly question, but can a time series have a linear trend?
Thanks

Hey guys!
We were asked to calculate percentage frequencies in a table, rounding it to one decimal place, and then creating a percentage segmented bar chart. Because of rounding, the percentage became 100.1% as the total for one of the categories - so when graphing, do I go up to 100.1?

This is for tomorrow, so i would be grateful for any help :)))))) Thank you!

Are we still required to do a 3/5 median line? This includes marking points and drawing a 3/5 median line.
A key example of this is VCAA 2011 Exam 2 Question 3b. ;)

Heyo,
3/5 median line is no longer part of the study design, so feel free to skip those questions! :)
Keep in mind though, the 3/5 median smoothing is still relevant to the current study design.

Good luck!

Hi everyone,
I just had a question on Data analysis. I was just wondering what the advantage of converting a two-way table into percentages would be, and if there is specific terminology I would have to use in answering the question. 
Thank you!

Thank you!

The advantage is that it's more useful to compare frequencies where the amount of data differs. So, if the amount of data was larger for one category than another (e.g. 30 total opinions from high school students and 12 from uni students), using percentages makes it easier to compare the relative frequencies.
I don't believe there is any specific terminology required to answer the question.

There's a good example for this on:
https://www.khanacademy.org/math/statistics-probability/analyzing-categorical-data/two-way-tables-for-categorical-data/a/two-way-tables-review

Hope this helps :)

Hey all, I'm not sure how to do this question and was wondering if anyone would be able to help me out

Geoff has a compound interest investment that earns interest compounding monthly. The balance of Geoff's compound interest investment was $4418.80 after 6 months. The balance of Geoff's compound interest investment was $4862.80 after 2 years. The amount of money that Geoff initially invested is closest to:
A. $4000
B. $4015
C. $4280
D. $4370
E. $4715

Thank you!

Hey all, I'm not sure how to do these questions and was wondering if anyone would be able to help me out

1. Geoff has a compound interest investment that earns interest compounding monthly. The balance of Geoff's compound interest investment was $4418.80 after 6 months. The balance of Geoff's compound interest investment was $4862.80 after 2 years. The amount of money that Geoff initially invested is closest to:
A. $4000
B. $4015
C. $4280
D. $4370
E. $4715

2. A printer was purchased for $680. After 4 years, the printer has a value of $125. On average, 1920 pages were printed every year during those 4 years. The value of the printer was depreciated using a unit cost method of depreciation. The depreciation in the value of the printer, per page printed, is closest to:
A. 3 cents
B. 4 cents
C. 5 cents
D. 6 cents
E. 7 cents

Thank you!

Hey, I don't have my calculator on me, but to solve question one you would use your financial calculator on the CAS.

Q1. Assuming that Geoff isn't adding money to this account, first you would want to calculate the annual interest rate. To do this enter the following in the financial solver.

N - 18 (24 months - 6 months)
I - (leave blank/0)
PV - -4418.80
Pmt - 0
FV - 4862.80
ppy - 12
cpy - 12
pmt at End.

Once you've found the annual interest rate, you can enter the following in your CAS,

N - 6 (Time taken to reach the first value mentioned)
PV - (0/leave blank)
I - (Enter value previously found)
Pmt - 0
FV - 4418.80
ppy - 12
cpy - 12
pmt at End.

This should give you your answer, (my guess is that it would be somewhere around $4280)

Q2. The Unit cost depreciation rule (from what I remember) is as follows
Vn = V0 - nD
V0 being the initial price of the asset
Vn being the value of the asset after n units of use
n being amount of 'uses'
D being cost of one 'use'

In this case, you are trying to find D. V0 = $680, 1920 x 4 = n (amount of uses) and Vn = $125.

In your cas you can simply type in Menu -> algebra -> solve (125 = 680 - (1920 x 4)x,x

This should give you your answer. Hope this helps :)

Thanks so much!! I should've done it like this haha I initially did trial and error bleugh

Also, congrats on your accounting & further scores! am definitely aiming for a score like that in further! :D
