GCSE Edexcel Maths - Working Out Marks HELP

Could someone how many marks I would get for each of these questions on the Calculator paper? Thanks

2c) If i got 7 for the scatter graph question would i still get both marks?

9) If i used kind of the wrong equation for the trapezium question but solved it correctly, could i get 2/4? Losing one mark for the incorrect answer another for the wrong equation?

11) For the driveway question, if i didn't multiply by 6 and did everything else correct e.g. simply did 11*4 then divided by 0.4, then multiplied by 38 and then worked out the discount, could i still get 2/4? Losing one mark for the incorrect answer and another for not multiplying by 6?

12b) if i put 2(3n-n^2) instead of 6n-2n^2 would i still get the 1 mark?

14) for the sausage pack question if i used a LCM that wasnt lowest after 60 (120) could i still get 3/5, losing 1 for the incorrect answer and 1 for the wrong LCM.

15b) If i didn't use tan but instead measured the bearing of A from C with a protractor, and then took that away from 180, which i then i subtracted from 360, to get an answer of 222 would i still get 2 marks/4. (I didn't see the this diagram is not drawn to scale)

For 18a) I think i may have added 206.60 and 209.70 to give 416.30 which i put as my final answer instead of 209.70, would that only drop me a mark out of 3?

18b) I think i did completely wrong however if i wrote a comparative sentence would that get me a mark? I divided her train ticket by 0.875 and her weekly bay by 0.95 instead of dividing by 1.125 and 1.05. And then i simply stated the amount in pounds her train ticket had increased compared to the amount her pay increased.

19) For the 3D co-ordinates question i think i got one of the three co-ordinates right would that get me 1/2?

23b) The stratified sampling question i accidentally multiplied by 60 when the sample size was actually 50 giving me an answer of 32 instead of 26 would that still get me 1/2?

25) I worked out the volume of the sphere but I didn't divide by two, I also worked out the volume of the cone but multiplied by 14 instead of 10. I didn't write a final answer. Would that get me 1/3?

26) For the quadratic equation I got 6,0 and my other answer as -10,-8. Would i get 4/5 for getting one of the solutions. Also if i possibly mixed up x and y when writing my final answer, but my working out shows i got y as 0 and x as 6 would i get 3/5 or 4/5?

27)If i correctly worked out the angle using the sine rule and taking away from 180 however instead of doing 1/2absinC, i worked out the length of side AD and multiplied by 2. Would that still get me 2/5? Losing 1 mark for the incorrect answer, another for not using 1/2absinC?
