yes, thats right: √3 sq . 5π/3 . 1/2 = 5π/2joshuaali said:Angle ACB (reflex) is 5π/3? If so, the area would be... 5π/2 m²?
Probability Q9himiniji said:oh i suck, i got the probablity stuff in question nine all wrong, i did it all with replacement for some reason, i cant believe i did that. Does anyone know how many marks it was worth? 3? 2? gah im so annoyed.
Then also 10)b) the last 4 mark question. and my answer for that crazy woman investing for her son was like $150 000 so i got that wrong too.
Oh and also i said october, not november. Does anyone know how many marks i lost? I think its about 9.
steff167 said:oh i messed up the probability and mobile phone question and then i didnt attempt 10b or supeerannuation. Im an average maths student and i struggled to get it finished and struggled from Q7 onwards, oh well, no more maths! everyone seems to have done really well.
Finally some people who don't exaggerate their performance.ktcrazy said:Omg I am so annoyed. I had the right answer for k in 8 and then changed it cause i didn't think it was right....well, there goes 5 marks...
You all seem to have done so well...I'm an average advanced student and i struggled from about question 7...
I agree. I think what I've found anyways is that an Ext student usually overstate what they got while Advanced students are more conservative. Just an observation from the past 2 years.williamc said:94-98/120 will be around the band 6 cut off.
There must be alot of fucking gun ext students on this. People getting 110+/120 is fucking nuts.
band 5 cut off will be around 67-70/120 in my opinon.
Well, I still think I got 66. Hopefully, I might be able to scrape into a band 5... maybe.williamc said:band 5 cut off will be around 67-70/120 in my opinon.
I couldn't remember the area of a rhombus so i did 2x1/2bh...hope it worked hahahaha. Didn't even look at q10 and i'm pretty sure i screwed up 9b. I probably made sooooooooooooooo many stupid mistakes. Hope scaling works in my favour and would hate to see my raw mark cos it would be pitifulBuiboi said:10 b i left out thats 5 gone
ummm 10 a) part 3 and 4 were wrong i think.. so thats another 4 gone
and another one i got wrong was the areă of the rhombus....lol i put 1/2 xy and yeah....
Yeah I forgot how to find the area of a rhombus too. I used 1/2 times the diagonals which I think is right. It came out with a nice number, anyway.SimoneL said:I couldn't remember the area of a rhombus so i did 2x1/2bh...hope it worked hahahaha. Didn't even look at q10 and i'm pretty sure i screwed up 9b.
