Pretty sure I got that wrong too, something like 100-25Pi and I knew it was wrong
I got that too, I think it's right

No waaaay that's one I wrote off as wrong
3. What did everyone get for the explanation part of the vectors question
4. (Original post by wildjones)
That one was the volume of the polygon- 30 x 25 or something, I think I got around 750?
Yh did put cm cubed aswell ? (Ur correct)

I think that it is but it should simplify down to 4-pi
7. (Original post by CopyThat)
Yeah i put something like ... 100, 25 and 5
not 5, it is 4
8. (Original post by Ace2233)
What did you get on the last question about the area of the shaded triangle? I remember getting something like (3-sqr6)/12.
I think I got the same
9. (Original post by ihatehannah)
not 5, it is 4
Yeah 4 sorry,

I couldn't remember so i just guessed :P
10. Please say I wasn't the only one who found this paper really difficult i USUALLY GET A/A* in all my papers but I found this paper ridiculously hard! I spent half the exam crying (
11. (Original post by PolarisVega)
And did anyone do the question with the inverse proportion and the table??
i got like 100, 25, 4 and 1?

13. I got 69 degrees for the circle theorm, 11 for the girls who went to art gallery, 7 x 10^ 8 for the standard form question, 45 days for the oil question, T= 5x + 20y for the formula question

Yep, but I don't know if you have to simplify the equation or not?
15. Q1 750cm^3
Q2 too vague and no timeframe
The class is a small sample/biased
Q3 p^7
g^2
k^6
10-5m
n(n-7)
45
90
No not enough varnish cos she needs 50cm^2 but has 37.5cm^2
60
T=5x+20y
(-3,-2)
11 females
100-25pi
36%
I compared median, IQR and range
150
7x10^8
X<7
7/5
2 4/5 in mixed fraction form
4/5
x=-0.4 and 4.4
X=-1.1 and 5.1
X=-1.7 and 4.7
Angle MST 69
Probability is 0.04
X=2&6
a+b
-a+3b
3/4(a+b) for vector
Point s is on both lines and it is point where they intersect
100,25,4
Final questions is (3-root6)/12
16. (Original post by Revathyvk)
i got like 100, 25, 4 and 1?
Same
17. Same I got something like that too
*phew*

18. What did you get for the activities day one ?
19. how is question 24) 100,25 and 4?
