UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016

Says 404 error??

Because it is a cubic graph, the points should be connected with smooth curves, check on desmos or a graphing app

Did anyone else get 80.1 for the last one? It's because at some point I rounded it to 2dp and then worked it out with that. I wasn't sure whether to round to 2dp or 1dp (if I rounded to one at that point sna then carried on my final answer would have been 80.4). I ended up deciding to go for the 2dp and then getting 80.1 because it was more accurate but I'm not sure cause everyone says 80.4

for question 1b i left my probability as 9/20... how many marks would i have got for that?

I actually feel really confident with this paper, there weren't really any questions that were very challenging, and hopefully I got that a* I also heard from other people that this was easier than the non-calc paper

Also, for Q24, I think you could simplify 2x/(x+1)(x-1) to just 2x/(x^2)-1, as this would technically be more simple

Hi I'm going to start and unofficial markscheme so add your answers
Reps are not necessary but would be appreciated

It would be really useful if you could remember the question numbers
1. Order numbers correctly and include a key
b) 9/20=
0.45
2a. 5a*2b*3c =
30abc
b. Factorise fully 3y +6 =
3(y+2)
c. Expand x(x-3)=
x^2-3x
3.
x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. Green- 0.09 Red- 0.36
6a. 20.3
b. 68.04kg
c. 2.61m
7. 3.8
8a. 4:3
b. 480 pixels
9.x= 124 degrees
10. 7.92
11.£42.29
12. x=144 degrees
13.
-2 -1 0 1 2
-1 3 1 -1 3
Draw curve
14. 3 Bars
15. No, because 7766.22 was greater than 7500 pounds
16. 128g
b.11g
17. 30.1
18. 10a^5b^4
b. y= 5p^2-x
19.11 males
20. x= 0.29 or x= -2.29
21. 29.25
22. F.d- 1.6, 3.2, 2.4, 1.8, 0.3
23. -1/3x+4
24. 2x/(x+1)(x-1)
25. 80.4

A* = Roughly 169
A = Roughly 132
B = Roughly 98
C = Roughly 77

Yes they are the same thing just multiplied by -1/-1

Oh nooo does that mean you get no marks for it at all?

yes it was 11 divided by 234 times by 50 giving 11

I got 40 on the last question, can someone tell me how to get 80.4. I used the sine rule and did 0.5x7x8xSinC=18
Then i worked that out until i had SinC=some thing and i did shift sine that number and got 40? People are telling me i had to use consine rule. And i knew my answer was wrong anyway becasue i checked it with the consine rule and i got some werid number

30.1

23. Was part a of 24.
The answer for 23 was 28.9cm
