I don't even bother with u. I just go straight to x+2/x=3lol I somehow didn't make the connection of using 'u' in the first question either.

Um ...... no.The question doesn't ask for when it doesn't rain, it asks for "the probability that it rains on fewer than 3 days", which shouldn't include zero days since no rain occurs
58/70 I reckon would definitely be enough for E4 (I saw in some other thread it's usually high 40s- mid 50s).Last week: let's perceive them with easy or no probability.
Today: let's fk a lot of them with this question.
Hoping 58/70 will be enough for an E4
yeah i wrote x + 2/x = (6 +- sqrt(36-36))/2 = 3For a 3-marker, I don't fancy you chance of getting 3/3 if you didn't show where you got that from.
yeah some of my 4u friends recognised the question but they also had relative difficulty with itDid you get out rhe last q ? Its a pretty common 4U q I believe so yeah defs skewed toward 4U students BUT I still didn't get it lol goes to show how dumb I am
Is it possible to still get 2/3 for a question where you sub in the wrong variables but did the right working out using those variables instead to get the answer?Amazing that you actually managed to factorise the quartic!
You will most certainly get 2/3, but there is a SLIGHT possibility of you getting 3/3 if the markers are lenient. Remember, the HSC markers don't necessarily strictly follow the marking criteria.
Yeah because it says "or otherwise"For rate of change, it says "use Pythagoras theorem, or otherwise." If I used another approach and got the same answer, will I still get 2 marks.
Yeah I wrote the quadratic formula. What I meant was I just didn't let u=x+2/x ( I did what aDimitri did)yeah i wrote x + 2/x = (6 +- sqrt(36-36))/2 = 3
So we don't lose a mark if we forgot x=/=0?for the parametric last question you actually have to do it with the equation carrotsticks got. i dont think you will get marks just for "describing" how it is a line on a circle with radius a or whatever it was. for those of you who go to NGO&Sons there was a very similar question in Module 1 of the Parametrics booklet. Overall i believe who ever got the equation x^2 + (y-a)^2 = a^2 will get the full marks. anyone working towards the equation will get some marks and anyone who didnt do this method will get 0.
Peace on the street SAAAAN
braintic more like shittic with a crappy response like thatA recurring decimal.
Yeah I think that is allowed.For the circle locus question, couldn't you just say that since OS is 'a' and find QS which is also 'a' and then jst conclude that it's a circle? If not then I'm screwed lol
