Albeno69 (stupid) further questions!

[Martoman]

Interest rate decreasing or increasing? I'd need to see the question but usually you find the final value of the investment for the original percentage then you place this as the intial value and change the percentage to what it is.

yea there is no such question but i dont know how to approach such as question and want to be fully prepared for the exam.
do u know the annuities formula cos the quest and essential have a different formula

[Martoman]

With the annuities you are probs getting confused with the + and - in between the terms? If so, the essentials shows the annuities for a loan. In Quest it shows annuities for superannuation (as well as a loan on page584). The difference arises after you think about it for a bit; the -ve in the equation will mean you are making regular repayments to pay off a loan (money you are losing to the greedy bank) wheras the +ve in super means you are adding regular amounts to a bank account (and thus gaining money thats what superannuation is).

For Interest rate changing refer to page 602 of quest.

aw thanks very much for clearing it up

i remember during the year i could find out standard deviation/variance on the cas calc but now i can remember how to do it can anyone help me?

[jasoN-]

Standard deviation: Statistics -> One or Two Variable (Calc)
Variance: you mean coefficient of determination (r^2)? If so its usually a LinearReg line between two variables. (Statistics -> Calc -> LinearReg)

yea i see this was with standard deviation but im pretty sure there is something in the book or something on the calc. and variance isnt the coefficient of determination its something different.
thanks for the help anyway

cas,
i remember soothing with the book button on the calc

[Albeno69]

doing 2006 vcaa exam 1 business maths module and i struggled on question 9 how do it on the cas calculator without using the interest.

[Albeno69]

hi also now doing exam 2 vcaa 2006 business maths module question 3C how do they get 25150?

[Martoman]

Answer is 25935.

N = 96
I% = 6.5
PV = -500
PMT = 200
FV=?     
P/Y=12
C/y= 12

Press FV then you get 25935.30411

That's why I switched to matrices from business maths...I hated it lol.

Apparently working out is drawing the financial solver box...f that...matrices rock!!
