Are you sure about that because all of my top set class got 3.8 myself included? I mean you might be right but I thought it would most likely be 3.8

Posted from TSR Mobile
(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.
3. [QUOTE=TheNerdxP;65604051]Damn. You see I thought when it came to people you can't round another person as you don't have an extra 0.2 of a person, so I rounded it down :/
Ive done all the past papers from 2003 till 2016 (i sat my gcse this year) and sometimes the exam is lenient and sometimes they wont accept it. I think if lots of people did your mistake then you will get the mark bc ur technically correct in the end

Yeah as long as your frequency densities were right
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
5. Anybody know the predicted grade boundaries for the two papers combined?

Do you think if I got about 70 marks on both non-calc and calc I could get an A?
6. what grade would 138/200 be?
7. (Original post by Purpleunicorn197)
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
it wasn't 0.36 and 0.09?

Must be such a struggle for you.
Shut up mate we dont care
9. (Original post by esmeralda123)
Definitely an A
10. (Original post by Barnewell)
80.4
or 80.1 we are having a school debate, you couldd say a maths debate
I got 79.9
11. For no. 2. 5a*2b*3c what was the answer. Cus I put 5a2b3c
12. (Original post by Tom1699)
Surely it would be 1/2 ab sinC as the area was 18 and you rearrange to find the angle which is 40.0
No, that would have given you only the other angle not the angle you're looking for. You should get 1-2 marks if you wrote that though.
13. (Original post by HateOCR)
is it ok if i got 80.8 for the last qutiones
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! @_

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. 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

are your sure for question 4 it is not the large packet.
15. On question 11 if I put £42.28 and did all the correct working would I still get full marks?

(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?
19. The medium sixe was the best for value i am sure of it
20. (Original post by HateOCR)
If you worked out the difference between 3.8 and 3.7 to 3.75 then u will see that 3.7 is closer trust me im not wrong.
You are wrong I don't know why you think you are some sort of genius
