Then there is nothing to question ... you're already on the right path :)

Can I ask what belief it is that you have never questioned? It is hard to respond when I'm not sure what I'm responding to.

A dunce cap for enjoying a movie? Interesting concept.

Just finished watching The Dictator with Sacha Baron Cohen. Hilarious. "Admiral General, welcome to New York City. And while you're here, I highly recommend a visit to the Empire State Building, before you or one of your cousins takes it down." "So ... is it a boy ... or an abortion" "I...

Re: HSC 2015 4U Marathon Answer with no working, if anyone wants to see if they are correct: y=12x-9

Re: HSC 2015 4U Marathon It would be 12!/(5!6!). It is the same as counting the 12 letter words formed from one A, 5 Cs and 6 Ds.

Actually, it IS sometimes true. The HSC markers decide on this before marking, based on the marks allocated and their assessment of what skills are being tested. But more often than not, it is not the case.

Re: HSC 2015 4U Marathon The geometrical solution is much easier. The vectors representing 1-z and 1+z are perpendicular (diagonals of a rhombus), meaning their quotient has an argument of (+/-)pi/2, meaning the quotient is purely imaginary.

I don't think it is a ratio. "solve for x:" means "solve for x such that". If it was a ratio, it would not be possible to solve exactly. I think √ has interpreted it correctly.

Re: HSC 2015 4U Marathon Different equation to mine, but Wolfgram gave the same answer.

Re: HSC 2015 4U Marathon Hm ... I got a massive equation which I had to type into Wolfram Equation Solver. It gave an approximate answer of p=0.660566 Do I need to check my equation?

Re: HSC 2015 4U Marathon Does this question allow for the possibility of multiple deuces?

As I said, scaling is all I have to offer. I teach maths and have little idea about the content and work involved in these subjects.

All I have to offer is scaling. I will not mention marks, because most year 11s don't have a feel for final HSC marks at this stage. Instead, here is a comparison between the percentile (the percentage of the state you beat in each subject) and the ATAR you would get if each of your other...

Yes, but I wouldn't expect he would have 30 minute periods. The point is ... something is wrong with that figure of 8 periods per week.

http://ace.bos.nsw.edu.au/ace-8068 Summarising: You can drop most subjects any time before your HSC exam. The exception is Ext 2 Maths, which can't be dropped after your school has submitted your assessment marks. Even then, you can't drop if your school has no way of assessing you for 2 unit...

Where do people come up with this crap?

Re: HSC 2015 2U Marathon Isn't the point of these marathon threads for HSC students to answer the questions, and for teachers to jump in only when there is an issue with the question, when a student has made an incorrect attempt at the question, or after a couple of days when no-one has been...

Surely your school doesn't still have 40 minute periods?
