When you're completing the square, you're essentially using x2 + 2xy + y2 = (x+y)2. Because of this, the coefficient of x2 must be 1. 4/25 + 10/25 = 14/25. I_F

Jono, your rules are almost there, but you've forgotten one thing: the coefficient of x2 must be 1 to complete the square. :) Another complete the square? Anyways, SoulSearcher is correct :p I_F

For great speculative fiction, I highly recommend Phillip Pullman's His Dark Materials. Utterly compulsive reading. I_F

You can sell the keyboard on eBay. AOLspeak without the age requirement. Anyways, perhaps there's a wire loose in your keyboard, and as you type and move the keyboard about the wire connects and disconnects, enabling and disabling Caps Lock. If you really don't like it, there is an option in...

Dude, there's hard, very hard, and haven't done it yet... :p I_F

Jeez, you guys get started early. I didn't get any Year 11 work till I strolled into school at the start of the year... I_F

You don't need to expand it out. You need to use the binomial theorem, which relates to the Combination function. I haven't learnt this yet, so I can't help you more on this point. I think this is right: Number of possible rows = 8! = 40320 P(alternate) = 2 x (4C1 * 4C1 * 3C1 * 3C1 *...

Condoms aren't foolproof against HIV, although they do help to greatly reduce the risk of infection. Statistically, they have a 1 in 121 chance of breaking during intercourse, which means they definitely aren't impermeable. The only foolproof ways of avoiding HIV are abstinence or knowing your...

UTS doesn't offer the EAS bonus, as far as I know. Most Sydney unis (outside UNSW's rural medicine scheme) don't offer bonuses to rural students. I_F

7 = (x.h)/2 (area) (1) 12 = h + x + sqrt (x^2 + h^2) (perimeter) (2) Therefore 14 = x.h x = 14/h 12 = h + 14/h + √(196/h2 + h2) √(196/h2 + h2) = 12 - h - 14/h 196/h2 + h2 = (12 - h - 14/h)2 196/h2 + h2 = 144 - 12h - 168/h - 12h + h2 + 14 - 168/h + 14 +168/h2 196/h2 + h2...

I live in the middle of nowhere, so if I apply to any of the University of Newcastle, Wollongong University, University of New England, or Charles Sturt University, I'll get a bonus 4 or 5 points on my UAI. :D I_F

I think it's a little ironic that people use the Bible to justify some acts, but don't quite follow through on everything the Bible contains. It's really a sign that some parts of the Bible just aren't relevant to today's society, and as a consequence, Christians just don't follow them...

Are you going to try for your AMus again after the HSC? I_F

He'd coerce Wilson into doing it for him. Or he'd play pretendies, all the while scoffing at the stupidity of Australian medical tests. I_F

Moral of the story: don't look up porn on an unprotected computer. I_F

Your friend is wrong. Enchant creature cards are still spells before and when they are played - anything in your hand that isn't a land is a spell (creature spells, artifact spells, enchantment spells, etc). :) I_F

Install away. I_F

Unless you get a particularly evil RAR file. I_F

A bad year and they still end up with 65% of their exams over 90... I_F

14% of minimum wage earners were in the top 20% of households (ranked by income) How is that supposed to work? If you're earning the MINIMUM wage, how can you be ranked in the top 20% by INCOME? Unless, of course, those 14% of people are the spouses of rich and successful business people, and...
