What did u guys get for the question that asked for students taking only one language and oh functions i got10/3x for one of them

18

What did people get for question 2 and the mean test mark question for the whole class?

17.4 i think

[thextractor007]

(Original post by TaranC)
q.16 was find the length of ab or something, using the cosine rule. for the angles question (15) i put 32 and 116

its 32 and 122

what did people get for the last question????

2.5

[desslop]

I didnt know how to do the Triangle one Can anybody explain how to get DC and AC??

Your probability answer is wrong; it's not 0.75. How did you get 0.75?

its 0.75
its bill then bill
bill joe bill
or joe bill bill

cosine rule
and the rules of lines

could you give more details??

[thextractor007]

(Original post by nithpriya)
could you give more details??

umm dont remember the question well but its suppose to be like:
ac squared=12 squared+6 squared- (2*12*6*cos28)
for dc it should be 12*7=(6+dc)dc... iam not sure for dc

[nithpriya]

Anyone who gets the paper please upload it immediately.

Cant wait to see if I get my first A*.(probably my only)

yeees

(Original post by TaranC)
how long before the paper and solutions come out?

19th may. thats what some guy said in the previous pages.

[Examstressman]

For the factorise out one, Did anyone else get Y^2 - 2y - 35, think it may have been + 2y and ivebeen an idiiot

[JackelJKL]

I got -2y as well.

these are all the answers i got:

1. 4.8
2.17.4 (total mean)
3. a)30 mins
b)21 km
c)13.27 and 16.28 (what time 24km away)
d) 31.2 km/h
4. a) reflection x=1 b) rotation thing
5. 105 degrees (32tan70 something)
6. -2, 3.5 (simultaneous equation)
7. 2x2x3x5x5 (300 as product of prime factors)
8. 67 (total rain in janurary)
9.a) x+8
b) y^2 +2y-35
c) square root of v/pie times h
10.a) 78000
b) 5.4x10^5 (weight of space shuttle+station)
11. donut shape next to normal circle(sets a n c')
12. a) drew graph b) 2.4 (x^3-3X-1)
13. a) 3x^2 -3 (differentiate x^3-3x-6)
b) dy/dx=45
14. 18 people studied 1 language
15.a)32 degrees
b) 122 degrees (opposite angles in cyclic quad =180)
16. a) 7.27cm
b) 4cm (CHORDS)(7x12=6xXD, XD=10, DC=4)
17.a) 18% (HISTOGRAM)
b) 200 total ppl
18. probability=0.75
19.a) inverse function=(x+2)/3
b) gf(x)=10/3x
20. -1 or 8
21. r=2.5

I got exactly the same answers as you, fingers crossed they're all correct!

[Coco406]

So I'm taking that most people found this paper a lot easier? Grade boundaries wouldn't just shoot up would they?

for 3C, i wrote 13:30 and 16:30. u think i,d get any marks for that?

I think it'd depend on the graph you drew.

Yes, they usually have a range of answers which they will give marks for. Especially if you've used the graph (and it looks like you have to them too). Personally I got 13:25 and 16:30 I think.
