well you're on 3 band 6's for pdhpe legal and business which don't scale spectularly, but if you perform well in your externals scaling won't be an issue. Your ranks in general maths and english are fairly good 10%~ for a school ranked 200 means 80+. 92 is achievable.
1) Limiting sum formula a/(r-1) where r is between -1 and 1
The ratio of the series is 2x, thus r = 2x
but r has to be between -1 and 1 thus -1 < 2 x < 1
-1/2 < x < 1/2.
2. I assume Solve 2sin2x/3 = 1 for -pi =< x =< pi. is meant to read
2(sin[x/3])^2 = 1
In which case the domain is...
That's nearly impossible, seeing as different schools will inevitably produce different sets of marks. Ask your principal or career's adviser.
- or you could post up your school rank and subject ranks and get a fairly good estimate here
I'm pretty sure the University Admissions Centre does not deal with HSC examinations. I think you're referred to the Board of Studies there. I'm also sure Lazarus is one of the most informed members of these boards, if he/she bothers to reply in this thread, then it'll be all cleared. I pose no...
Sorry, I'm open to correct but I thought that when your raw mark is 'changed' to an external mark, the process is called moderation? Maybe I have the terms confused and use them synonymously.
Just a quick response on it to save you searching:
Upon receiving your HSC mark (ie the average between your external and internal marks), that mark undergoes scaling.
Scaling the mark means that it's changed, the changed mark is then used to calculate your ATAR.
Harder subjects...
Extremely hard to tell, depends on your cohort's performance in the external examination. What matters is your rank and not mark. Perhaps 60-70% RAW for a moderated mark of 75-80 I would assume
