    Will there be a unofficial mark scheme like the one for the first paper? With the question, answer and number of marks.
    Depends if someone leaks the paper on youtube

    No because probability is a decimal or percentage, not fraction

    Hi I'm going to start and unofficial markscheme so add your answersReps 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 =30abcb.
    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. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.0.4+0.15+4x+x=10.55+5x=15 x=0.45x=0.094x=0.36Green- 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 3Draw 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
    23.28.9
    24a. -1/3x+4
    b. 2x/(x+1)(x-1)
    25. 80.4
    I think:
    Q2a was 1mark
    Q2b 1mark
    Q2c 1mark or 2 mark?
    Q3 I believe was 3 but could be 4
    Q4 was 4mark
    Q5 was 2mark(?)
    Q6 a b and c I think were 2 each so 6?
    Q7 4or5marks
    Q8 a and b both equated to 4 marks?
    Q13 a was 3 marks I believe
    b was 2 marks
    Q14 at least 4 marks
    Q15 5marks(?)
    Q16 a was 1 mark
    b was 2 marks
    Q18 a 1 mark
    b 3marks
    Q19 was 2 marks
    Q24 a 2 marks
    b was 3 marks
    Q25 5 marks?

    As you can see I am unsure about many so PLEASE correct me and fill the blanks!!!!!!!!!!!!!!! Thanks

    This is true but a fraction is correct too because when we are given probability questions with tree diagrams they are usually in the form of fractions

    Yeah you'll definitely get some method marks for a correct substitution

    I got the same as you did... using the same method but people at my school got a range from 40.0, 45 47,5 and going all the way up to 80.0 and 80.2... Don't know what the right answer was though

    For the very first question is it acceptable to leave it as 9/20 as it is a probability?
    Yes I am sure you can as that is right

    If they want is to 1 dp then you have to test halfway between the two 1dp values (so 3.75) to know whether 3.8 is closer or 3.7 so you would have lost at least 1 mark
    Wait a sec, x^3 - 5x = 34

    3.7^3 - 5(3.7) = 32.153
    34 - 32.153 = 1.847
    So 3.7 is 1.847 away.

    3.8^3 - 5(3.8) = 35.872
    35.872 - 34 = 1.872
    So 3.8 is 1.872 away.

    This shows 3.8 being 0.025 further away than 3.7. 3.7 is closer. These are cubed numbers so even though you could round up from 3.75, the number gap changes as the numbers get bigger, so you count just assume to round up. They only care about 1d.p. numbers, using 3.75 doesnt matter. You have to find which 1d.p. is closer, and its 3.7.

    80.4
    or 80.1 we are having a school debate, you couldd say a maths debate
    You get 80.1 if you didn't store all the decimals and 80.4 if you did.

    The answer was 80.4. You would get 80.1 if you rounded the answers mid way through the question not only at the end.
