it was a cubic graph that cut the axis 3 times, looking a bit like an N yes

yes squiggly N
Ok thank you! Made me so relieved! :smile:
Ok Thank god! xD Thanks for messeging me back!
1.a) Ordered correctly with correct key b) 9/20 or 0.45 or 45%

2. a) 30abc b) 3(y+2) c) x^2 - 3x

3. Form equation 4x + 8 = 45 then solve for x = 9.25

4. Divide each price by amount to show 18 bags is best value.

5. Green = 0.09 and Red = 0.36

6. a) 20.3 b) 68.04 c) 2.61m

7. 3.8

8. a) 4:3 b) 480

9. 124 degrees

10. 7.92

11. £42.28 - £42.30 Anywhere in range

12. 144 degrees

13. Plot (-2,-1) (-1,3) (0,1) (1,-1) and (2,3)

14. 3 metal bars

15. £7766.22, so no it has not lost half it's value, it has lost £7233.78

16. a) Median = 128 b) IQR = 11

17. 30.1 degrees (1dp)

18. a) 10a^5b^4 b) y = 5p^2 - x

19. 11

20. x = 0.29 or x = -2.29 (2dp)

21. 29.25

22. 41.9

23. correct histograms with FD of 1.6, 3.2, 2.4, 1.8 and 0.3

24. a) -1/(3x+4) b) 2x/(x^2-1)

25. 80.4 degrees

yeah 3.8 because 3.75 was the closet to the answer, but 1dp so 3.8


Definitely 3.8

Original post by OllieBiggs
Please can you make a separate thread with a picture to the paper


Not allowed to show the paper I'm afraid sorry. Something to do with copyright.
Any ideas on what you need to get overall to get a C? I think I got around 37 marks on the first way, and I'm scared I didn't get enough in paper 2, even though it was an "easy" paper :frown:
What were the total marks for each questions?
