Didnt you have to just divide it by 5. I hope thats it.

What was the question about ?

Unfortunately it has a graph in it, so it is a bit hard to explain if you dont have the exam/ visual! It was a question on five median smoothing.

I also got a different answer to the original user for question 26! While they put E, I put D! What did everyone else answer?
The question for 26 was-

Ray deposited $5000 in an investment account earning interest at the rate of 3% per annum, compounding quarterly.
A rule for the balance, Rn, in dollars, after n years is given by:
A: Rn= 5000 x 0.03^n
B: Rn= 5000 x 1.03^n
C: Rn= 5000 x 0.03^4n
D: Rn= 5000 x 1.0075^n
E: Rn= 5000 x 1.0075^4n

E: Rn= 5000 x 1.0075^4n

I did E as well, because theyre asking for the rule after a year and there are four compounding periods in a year. I might be wrong tho.

Question 20 was 5 mean smoothing, not median, you just divide 2160000 by 5 to get D. Question 26 was E - D gives the balance after n quarters, not years.

my reasoning for e was basically the same, lemme walk u through what I was thinking. idk if I was right though bahaha

so we start with 3% pa and divide it by 4 for our 0.75% per quarter, which  eliminates a b and c. i thought d would be the rule for balance after n quarters, so I chose e over d since there are 4 quarters in a year. did I explain that ok ?

[The_excosecant]

can anyone send or email pictures of the question book, core + module to me, supervisors didn't give us the option to keep it at the end of the exam.

Yep, hopefully we're right
