Last question
3-Root 6/12
Can you tell me the question so I can confirm your answer?
2. (Original post by Lakshii)
how many marks was the last question ?
Three, I believe.
3. I think it was: find the shaded area, side lengths were both root 2 over 2, then the fraction of one side was root 3 over 3. I got 3 - root 6 over 12
4. Can people attach question numbers preferably with the answers? Method would be appreciated.
5. (Original post by YAY GCSE)
For the X^2=4(X-3)^2 i got 3 but i dont think thats right...
I got 3 too

Could you possibly draw this for me? It's hard to visualise what shaded area it is!
7. [QUOTE=erodedsoul;65190747]I got 0.4 on the probability

well, you should have got 0.04 actually

What was the whole question?
11. Mr M didn't you say that discussion of the exam isn't allowed until tomorrow?
12. For the question x^2=4(x-3)^2

Once you simplify and solve and whatever you get (3x-18)(x-2), so x=18 and x=2
I accidentally put (3x+18)(x+2) there fore i got x=-18 and x=-2. How many points would i lose?
The question was either on 3 or 5 points
13. (Original post by ewales)
Root 2 + 2 was the first triangle on both sides (not the hypotenuse) and on the second triangle the height was 3 + root 3. But the length was the same and the shaded area was between the triangles.
This is very hard to visualise from words, any rough drawing for me to go off of?
14. Was the number of 16 year olds 150? (box plot question)
15. What was the answer for the proportion question?

(K3)2

Didn't have enough litres

Solve X2 = 4(x-3)2 =3?

36%

0.04 probability

90 teachers

Table = 100,25,4

Idk whether these are right
