[Do you mind explaining how the answer is D for question 19 core. I know that they used effective interest rate, but why?]

Hey guys!

I got 40/40 for exam 1 in Further maths, if i get at least 56/60 for exam 2, what could my study score be?
Im currently rank 1 in my cohort

How do you work out Question 23 of the Core?

[FMt3135]

How do you do Q7 in matrices? Thanks

[Guest1256]

Hey guys, sorry to bother you but just wondering what full sacs, 36/40 and 60 would equate too? Also the same scenario but 58/60? Thanks guys

[meme01]

got 33/40...is it possible to still get score of 42? rank no 1 in my class

Hey everyone,
can someone post a solution to question 5 in the graphs and relations module?
Thanks

How do you work out Question 23 of the Core?

Just got to work out the interest rates for before and after the change. So
967.08/230256.78 = 0.0042
0.0042 X 100 = 0.42%

996.99/226588.02 = 0.0044
0.0044 X 100 = 0.44%

Difference of 0.02%
They're both monthly rates so you have to X by 12 to get the annual rate.
0.02 X 12 =0.24%

So there's a 0.24% increase per annum which is option A

How do you do Q7 in matrices? Thanks

                 
(There's probably an easier solution, but this is what I did)
A₃=TA₂-D
A₃+D=TA₂
T^-1A₃+D = A₂

And then just put the actual matrices in your CAS.

this yr exam was harder than last years for sure

It's about which is your explanatory and which is your response variable. The change in the explanatory explains the change in the response

Hey guys,

If this years grading distribution scores lower so that it’s easier to get an A+, will it be easier to receive a higher study score if I’m already at the top quartile?

A lot of my friends have been saying that they could get a higher study score if the rest of the state do bad... I’m not too sure how it works

Thanks

The study score is a measure relative to the performance of the state. If students overall do 'poorly' on the exam, the stat distributions will reflect this and the score requirements for some grades may move, meaning an A+ could require slightly less marks for example.

So in theory, if students struggled on this years exam/s but you did well, you will be in a position to get a good study score, but keep in mind that the very top students in maths historically always do well, its the mid-rankings that are the most volatile from year to year.
