This is really useful however I can't remember how many marks each question was worth and I don't have a copy of the exam paper. Could you please include the marks for each question? Thank you.

X3-5x=34.
Assuming X=3.7 would give an answer of 32.153, its difference from 34 being 1.847. However, assuming X=3.8 would yield an answer of 35.872, its difference from 34 being 1.872. Since the difference between 34 and the value of X as being 3.7 is smaller than the value at 3.8, X=3.7.
Hope this helps.


That's exactly what I did!

Hey guys I got 211/200, do you think that's gonna be enough for a B!?


Assuming you mean 111? cx i'd have thought that would be enough, the grade boundaries should be fine c:

For the question with the triangle inside of a triangle where you had to find X how did you work it out??
Because I found a side using Pythagoras and then used trigonometry to find the angle


I used trig to find the angle of the bigger triangle and took 30 away from it
Original post by mrpaper
how was it

wondering what you got on the last one?


i got 81.2
Original post by 34908seikj
Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18


56Sin(x) = 36

Sin^-1(36/56) = X

x = 40

???

I think I did it wrong then.


I think there was more steps because it was a 6 marker. After that you have to use the sine and cosine rule... At least that's what I did. Hope I got it right.

um hang on, arent u meant to test 3.75 and 3.75 is less than 34, therefore x has to be in between 3.75 - 3.8


There was a big debate earlier, i put 3.7 but either way, a few marks cant make a massive difference
I got 3.7 because you had to pick the smallest one and 3.8 was too big
got 81.5 for the last one i don't know how

it was 1/-4-3x so im not sure, youd probably get 1
Does anybody know if I'll still get 1 mark if for the Histograms I mixed up class width with the median..? :/

(Annoyingly missed the - sign off number 23 but hey what can you do)


well you could have checked your answers worked by substituting them back - obviously

Why didn't you take June 2015 into account?


It's an anomaly, a big one.
Does anyone happen to have any worked solutions?
Original post by WaveyH
If I correctly remember, the 2013 paper which was arguably the easiest paper ever was like 130 something for an A so you should be fine


thanks :smile:
