Can I access the paper anywhere?

Yes all those questions on the floor plan were only 1 mark.

Can someone post what they got for Question 26 a) iv)?

wat was the question for it?

I got she will expect a loss of 50 cents

wat was the question for it?

financial expectation using the 2 spinners, i more than likely got it wrong since i got -$1.50

your right 9 is C i got 15 too, but i forgot i changed it after redoing it

 

[Skriker]

OMG I AM SUCH A CUNT. I didn't look at my graph properly on my calc and got C instead of D.....My life is over.

For Q26 (a) (iv) with the 'Financial Outcome' I got -$1.50 from:

($7 * 1/3) + (1/2 * -$5) + (1/6 * -$8)

Multis.

1 - D
2 - A
3 - B
4 - C
5 - B
6 - D
7 - B (if scores are distributed to the left, then it's positive)
8 - D
9 - C
10 - C
11 - B
12 - A
13 - A
14 - B
15 - B
16 - D
17 - C
18 - B (I think)
19 - C
20 - C
21 - A
22 - A

We got nearly the exact same. Only difference is 10 (i guessed it so your probs right). And 19 i put D (which seems to be correct) and also for 20 i put A

this is what i got, questions that i'm not too sure about: 10, 14, 18

for the financial outcome my working was:

4/12 x 12 + 6/12 x 0 - 2/12 x 3 - 5= -0.50

i think from everyone else's answers for this i may have got this wrong wahhh

 

[engie_benji]

Was anyone silly like me and forget to do a negative gradient on the back page? making the formula $=-4000n+60000

25 (d) ii) the interquartile range for females
8,9,11,11,12,15, - 11+11 divided by 2 = 11 16,18 ,18,18,20,21,27,34 - 20+21 divided by 2 = 20.5

Interquartile ranger = upper - lower
= 20.5 - 11
9.5
Did anyone else get this?

 

[Skriker]

Found it pretty easy compared to recent papers, though I made a few really silly mistakes ><.

Can someone please post a link on here when/if they find solutions to the paper?
Thanks
My answers-
1 D, 2A, 3B, 4C, 5B, 6C (it's not D as the y intercept is greater than 0 thus the formula would be a^x + 1 or w.e.), 7C(silly mistake), 8D, 9C, 10A, 11D(silly mistake once again ), 12A, 13A, 14B, 15B, 16D, 17C, 18A, 19C, 20C, 21A, 22A.

If 6 and 10 are right, you have made my FUCKING DAY. because I guessed No 10 and wasn't too sure about 6

actually no, i think im right, there's a question just like this from 2010, and i looked at the working out and i did the exact same thing, so hopefully its goood

It was lose $3 so you should have done 2/12 x -3 - 5= .....

i didn't lolll

7 - B almost certain
10 - can't remember but you had to use the compound interest formula.
12 - A
15 - B (I think it was a trick question, correct me if im wrong!)
18 - Either A or B I couldn't decide so I chose one but i dont remember lol.

kiddo, you do know for 12 that you had to flip the equation on one side ( the right side) then cross multiple. Thus the answer was D.
