I got 3.7 too but it seems more people got 3.8 :/
I got 3.7

The question asked you to work out the closest value that 'x' could be (to1 decimal place) if ("x cubed") - (5 multiplied by 'x') = 34

If you sub 3.7 into that equation you will get an answer of 32.153
If you sub 3.8 into that equation you will get an answer of 35.872

To then work out which is closest you had to work out the difference between each answer and 34.

For 3.7:
34 - 32.153 = 1.847

For 3.8:
35.872 - 34 = 1.872

Seeing as 1.847 is a smaller number than 1.872, it means that 3.7 is the closest value of 'x' to 1 decimal place

It was

3.7
No bc it's smaller than 3.8 but bigger than 3.75 so it is 3.8

An A is probably about 130-135
That sounds about right.

Woouldnt 23 be 3x+4 because you cancel 3-x and x-3 out??
No its like saying 6-2 is the same as 2-6. They are different so u dont cancdl out

46.3?
I got that too

7. For the cosine question, why did you multiply by 3? Shouldn't it be by 2 since it's a^2 = b^2+c^2-2bcCos(A)?
8. For the quadratic formula who got -0.20 and 3.20?
9. x³-5x= 3.8 is wrong or nAH
10. Fast baller..star sigining for the paki internetional team also porn all the way and btw 1+1=69

Your wrong it was 100 percent 3.8

Yeah apparently, we worked out the wrong angle.
What about that trig one? I got like 30 point something
Oh dang, hopefully we get some method marks though& Yeah same, I'm pretty sure I did anyway, definitely rings a bell
15. for the last question, how many marks do you think I would get if I did everything right method wise except I forgot the 0.5 for the sinC area part?
like would I get any for a mistake carried forward or something?

Perimeter x = 9.25
Counters = 0.09 and 0.36
Trail and Improvement = 3.7
Parallel Lines = 124 (might have been 126 i can’t remember)
Polygons = 144
DMV = 3
Compound Depreciation = no, care is worth £7766 or something
Pythagoras and Trig = 30.1
Stratified Sample = 11
Quadratic = 0.29 or -2.29
Bounds = 29.something
Sectors = 28.9 (around that)
Last one = 80.4
Perimeter was 10.25
17. For the ratio question I got 4:3 as the simplest form of 720:540, then 480 to change the ratio to 3:2
18. I got 80.1 on the last question, I felt so happy until everyone said they got 80.4
19. Suck it hard 8====D
20. I dont remember the question numbers..
smallest packet is best for value
11 students
IQR: 11
Pentagon: 114
