Probably not.

I think the range will be 80.3-80.4 or 80.1-80.4 depending on how people rounded. But maybe! But I can't imagine the range being too big!

Good luck though! @_

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

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. 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
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
23.28.9
24a. -1/3x+4
b. 2x/(x+1)(x-1)
25. 80.4

On question 11 if I put £42.28 and did all the correct working would I still get full marks?

Ah phew because my densities were right and by the looks of the unofficial mark scheme, I've gotten 100% so I dont want to sacrifice my chances for a silly error like forgetting to label an axis

--------my answer--------
(before all this below i did 3.5 and 3.6)
3.73.7^3 - 5(3.7) = 32.153
34 - 32.153 = 1.847
So 3.7 is 1.847 away.

3.83.8^3 - 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. Therefore, the answer is 3.7, even though 3.75, the midpoint between them gives an answer smaller than 34.

The exact answer that they are looking for rounds to 3.8 so therefore why would you round it to 3.7

That's great. What do you think you'll get in non-calculator?

If you worked out the difference between 3.8 and 3.7 to 3.75 then u will see that 3.7 is closer :smile:

trust me im not wrong.

You are wrong I don't know why you think you are some sort of genius

lol definately they will go up. 170 is safe to think you have A* and 140 for A. It may not actually be that high, but will be like 135-140 for A and 165-168 for A* in my opinion.

What do you think I will need for a B? Don't even care if it's a low b

This would work if we weren't talking about indices. Because we are talking about indices the difference can be greater between the two numbers but the actual solution can be closer to the higher number.
