it was 3.25 cha unlucky, i made sure that i was right aswell, and also 4.66666666666 seems almost inevitably incorrect as edexcel barely ever use bizaare numbers for an x value unless the total value is an integer or an number under 3 significant figures

Lol cheers. Just realised that I didn't read the question correctly and thought that the sides were x+10 and 2x+ 3, not X+ 10 and X+ 3. Should only lose 1 method mark, maybe 2 so it's all good
4. Yeah that's right I read the question wrong lmao
is that you just remembering the question or is their a way to access the test we did today?
Unfortunately I just remembered it, I haven't seen the paper since the exam

Remembered it.

The t question and the rectangle in the shape is the same question!
Don't worry too much about it...some of the questions were pretty difficult
Theres always Applications 2 as well, I'm sure you will do fine
Ah yes they were. Hopefully! I only got a C last year so I'm praying for a B, maths is not my forte

as long as you have applied the correct working out to your wrong answer u will only lose a mark.

Really annoyed because I wanted to beat my mark from last years exam for methods. Although I know I've lost at least 4 marks from this question and the angle in the kite just because I don't RTFQ so annoyed tbh, at least I've learnt something though ahaha!
10. Unofficial mark scheme (some of it):

75 Euros for the first question,
31 degrees for the kite,
87.5% for the last one,
13 for stratified sample,
the supermarket was the better choice,
linear programming - shade the bottom part and the point (44,44) to find the profit (which is £19000 and something),
4x for the rectangle in the rhombus question,
3.25 for the rectangle and the big rectangle (perimeter)
the flowchart - the £0.25 is replaced by £0.30 ....

so far, gonna make the rest in a bit.

Tell me if anything needs changing ../
11. Does anyone know the grade boundaries?

Also, I'm a new member.

Did you get 4x for the t expression in that question about the shaded rhombus and the rectangle
16 x

I'm expecting the boundaries to be no lower than 84 for an A* and no higher than 88 for an A*. Tell me if you want the other ones.

Is the linear programming one not (92,20) and that gets a profit of 19,120 because when it's (44,44) I only got a profit of around 17000 something
16. I got t=4√10x for the rhombus question, seems like I should've learnt the formula for that (or actually read the question properly and realised that the area couldn't have been the width times the height).

The length of the side with the X with the two rectangles was 4.6 recurring

2(6x) = 6x+ 26
12x= 6x + 26
6x = 26
X= 4.6 recurring
x = 4.3 recurring*

16 x
Nah
You got 16x squared for the shaded area, then you had to squareroot it to get 4x

The answers like 3.25 anyway lmao
20. How did everyone find a2?
