# UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016 Watch

1. (Original post by NeedsHelpalot)
Does anyone know if there is a november resit for this paper or not and if so i when is it (under the old spec)
November 2nd and 4th. Not much time to revise between exams !!
2. I got 80.4 for the last question however I did not use the method described. I did not use the sine rule, I mainly used Pythagoras and the cosine rule. I got the correct answer so does this matter, is there more than one way to achieve the correct answer?
3. For question 13 part b do you still get one mark just for plotting the dots at the right postion even if its not a curve?

There is more than one way to get the answer but Pythagoras isn't one of them (can only be used with right-angled triangles)

If all plotted correctly, then yes.
6. Will I lose a mark if I didn't label my histogram
7. (Original post by Roquebrune2014)
No because probability is a decimal or percentage, not fraction

Posted from TSR Mobile
Probability can be written as a fraction.
8. I think the grade boundaries will be similar to last yrs so about 160ish for an A*. I think i got 88/89 in this paper. Timing messed me up woulda got about 93ish if it wasnt for timing
9. Could i have put 2x/x^2-1 for second to last qestion
10. [QUOTE=AspiringMidwife9;65628883]Probability can be written as a fraction.[/QUOT

It can be either - they should all be accepted.
11. Isn't the answer to 19) 10 males? It came out as 10.89 but you can't have .89 of a person?? Unless I've got confused

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

Sorry for the hold up with the questions
1. Order numbers correctly and include a key (Stem and leaf) (3 marks)
b) 9/20=
0.45 (2 marks)
2a. 5a*2b*3c =
30abc (1 mark)
b. Factorise fully 3y +6 =
3(y+2) (1 mark)
c. Expand x(x-3)=
x^2-3x (1 mark)
3. Perimeter of a rectangle with side lengths x and x+4 is 45
x+x+x+4+x+4= 4x+8
4x+8=45
4x=37
x=9.25 (3 marks)
4. Smallest packet was best value for money because it was cheapest per bag of crisps (4 marks)
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
0.4+0.15+4x+x=1
0.55+5x=1
5x=0.45
x=0.09
4x=0.36
Green- 0.09 Red- 0.36 (3 marks)
6a. Body mass index= m/h^2
Mass= 50kg
Height= 1.57m
20.3 (2 marks)
b. What mass will result in a BMI of 21 with a height of 1.8m
68.04kg (2 marks)
c. Tom's skis can be a maximum of 145% of his height what is their max. tenght (Tom is 1.8m)
2.61m (3 marks)
7. Trial and error. x^3-5x=34 with a number between 3 and 4
x^3-5x=34
3.7 gives you 32.153 which is too small
3.8 gives you 35.872 which is too big
So you go in the middle at 3.75 and if it is too big then its you go with the smaller option and viceversa so 3.75 gives you 33.984375 which is too small so you go for the larger option of 3.8
3.8 (4 marks)

Does anyone have the answers for the Foundation Calculator paper please?

If you didn't work out the value with X=3.75 you won't get full marks even if you've chosen the correct answer
Incorrect, in the June 2015 exam I didn't include this in my working and when I received my marks report, I had been given 4/4.
17. If your lucky, but it did ask for the value, not the ratio so its unlikely, but possible
