D/w I made some reallly stupid errors
Like on that z score graph, the alcoholic drink question, the probability questions =[

 

[Emmarr]

lets not get started on the second section.

I kicked ass in some sections but the majority of it i didnt. I know ive failed now, im disapointed in myself, i could have studied better. My parents have all this pressure on me, and if i dont get a decent mark there going to blame everything i have done e.g go to my bfs house once in like a week.

so im screwed.

i look at the answers here and the ones i have and im like where did i go wrong. I have to admit i thought this one was easier then trials.

 

[Kiim2507]

Haha I definitely could have studied harder
Me and my friend may or may not have gone to see a movie on wednesday looool

ahhh! *facepalm* x 100.
ehhhh i somehow didn't even realise till i looked on here... that i forgot to add the flight time to the 5 hours :| before moving onto the next Q.
i am feeling... incredibley.. smart right now :|

*applies for job at council, as one of those people who holds up stop signs*

Uhhh, grr. Forgot the time diff 5 hours as well. Your not alone

Pretty sure i screwed that exam up
Looks like we'll be coucil workmates

Those workers get $25 an hr.
With the hours they work...
Not too shabby, as far as things could go.

 

[K-risty1990]

Haha, true
&& They don't really do much at all,

their asses, where i'm from anyway

Maybe failing isn't so bad after all Lolz..
Helloooooo council wages!! woot woot

seriously

the last question of the exam with the area of the tunnel. That was the stupidest question i have ever seen, and it had nothing to do with what we taught about the simpsons rule formula.

I found the answer through trial and error trying to put values in for a and b to get 600m2.

I found if a=8 and b=13 it equalled 600m^2.
Then by increase 8 till 10 i did more trial error to find that 13 equals 5 hence it decreased by 8m.

But it was friggen stupid and took 20 mins of my valuable time to work out.

Did anyone else do it differently??

how u do MC Q 15 & 21?

just curious

 

[lozzie22]

What kind of disgusting human being would do general maths- you people sicken me. keeping private school tradition and crusing towards uai of 100.

hahaha. what a wanker. seriously. i think ide rather keep my money. and my social life. people like you are the real sickening ones, i hope you get hit by a train.

 

[haydezats]

I ended up getting 91 which I am really happy with considering how much everybody else hated this paper and went bad in it.

I was hoping for over 90 and got it, I'm not bragging but I'm counting on general to get me into my course. thx for posting the answers and thx everybody for helping me out over the past year, cheers!:uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh::uhhuh:

It would've been nice if i've seen this before the exam...

 

[henry08]

Can you explain how you got 28, (IV) please. I thought the simpson's rule question wasn't actually that bad, with the financial math questions being harder. What the hell is z-scores lol? Gotta love the multiple choice as well.

 

[henry08]

Wikipedia and a couple of other sites just taught me z-scores.

 

[Bonny13]

It would've been nice if i've seen this before the exam...

it would have been nicer for everyone if we saw the exam before hand ...dah but appart from that the paper wasn't that bad. I mean if u knew ur shit you would have been fine

Do you mean the body mass index question?

B = m/h^2
21 = m/1.625^2
Therefore m = 21 x 1.625^2
= Whatever the answer is

 

[Kiim2507]

how u do MC Q 15 & 21?

just curious

Q15 - (320 x 12 x 5) - 16000 (I think)

Q21 - Sub in a value for the radius i.e let r = 2
Sphere - V = 4/3 x pi x r^2
= 33.510...

Cylinder - V = pi x r^2 x h (h = 8 as the question says the height is four times the radius)
= 100.5309...

100.5309/33.510..'
= 3
Therefore the ratio is 3:1

B = m/h^2
21 = m/1.625^2
Therefore m = 21 x 1.625^2

LOL, when I was doing that question at the start I forgot to convert cm into m and I was getting healthy weights of like 3000kg I almost cracked up laughing in the exam hall, but realised and got the answer

 

[Kiim2507]

Lol yeah I think pretty much everyone sitting the test did that at first

I'm still not quite sure about answers to the 4 mark cheese question. Four markers are usually trickier than they look, and although this DID look tricky, the answers posted up seem a bit too simplistic to me. When I first looked at the question, I got those answers, but after thinking about it for a bit, it didn't look right to me.

Length – Circumference of a sector multiplied by 4.
40/360 x 2 x П x 15 x 4 = 41.9cm (to 1 dec. Place)

Depth – Depth of the sector multiplied by 3.

7x 3 = 21cm

Height – For a 4 mark question, I don’t think height of the box is not merely the radius of the sector shown. I reckon it’s far too simple to be that. How can the height of the box be 15cm if the radius is slopping up? This is my working out.

Circumference of the sector divided by 2 (to break the sector into a right angle triangle(ignoring its curve))

40/360 x 2 x П x 15 = 41.889...

41.889/2 = 5.235987..

Now use the radius of the sector (15) and Pythagoras’ theorem to work out the height of the sector.

15^2 – 5.235987^2... = 197.5845...

Square root of 197.5845 = 14.1 cm (to 1 dec. place)

That's what I got...I don't know if it's right though
