I remember that question^. The financial expectation is something like (240x1/96) + (120x1/95) + (60x2/93) And therefore the financial gain is expected to be the financial expectation -$6 which gives -$0.75 I can't remember for the life of me the probability they used to get the answer though...

Yeah, answer for the Shelley question is 9. Anyone mind running me through their logic? I'm guessing it's a logarithmic question like said up there^? Also, dat year 11 stuff. Capture re-capture, dividend yield, types of data, types of surveys... anything else to remember?

dat feel when everything is spoonfed to you dat feel when not much work required to get 90% raw marks dat feel when easy to obtain top ranks because everyone else is stupid af dat feel when more time to dedicate to other subjects dat feel when easily finishing exams in time bc they don't...

Anyone know how the hell to do mine up there? edit: Shelley invests her savings in an account. The account pays 8% p.a. interest compounding quarterly. After how many years will Shelley's investment double in value? Also, opinions on actually bringing a highlighter in? Do you guys think it'd...

I'm 2/130 and I have no fucking clue unless it's really obvious either. It's so damn ambiguous to me lulz.

They give you a formula sheet with like everything you need on it. You can look up the formula sheet they'll give us on the BoS site.

That 1.5 hour time gets put up to 4 hours worth of double time. That'll fix up your answer. Remember, he gets payed a minimum of 4 hours. Also, does anyone know how to do this question? I really don't see any other way other than inverse logs which I don't think would be in general maths - so...

no ben howard or blackmill? plsgo you all suck

Thanks heaps. I was just wondering about the extent of scaling because for the ATAR I want to achieve, I need a final mark of 70 in chemistry (according to the array of calculators I've used - they shouldn't differ too much for this year I'd imagine). I messed around for the entirety of the...

Mark alignment has nothing to do with ATAR calculation right? If so, how much are the "harder" subjects generally scaled before a final exam mark is given? For example, does anyone know what a raw mark of 80 in chemistry would be scaled to (on average/approximately)? And more importantly, why...

Yep.

Cheers. I'll give it a whack tomorrow when I'm not dead. We do. It's pretty (extremely) basic though. So some harder stuff is great.

I find it's a lot easier when you break down the question. Is it a right-angled triangle or not? (So basically, can we apply pythagoras and trigonometry rules?) or is it a non-right angle triangle and therefore we have to use our cosine and sine rules, etc. Then just determine what sides and...

The harder the better, please do. If you're gonna post an answer make sure you convert the colour to white nomsayn to avoid spoilers, just use the bbcode your text here without dat * edit: uwotm8 you're allowed to post questions rait?
