20. Watch faces

36 : 37 (4 marks)


21. Stratified sample

9 (2 marks)


22. Quadratic formula

$2x^2+7x+4=0$ (3 marks)


23. Graph transformations

a) Translate graph 2 units up (2 marks)

b) Stretch graph by scale factor 2 in the y direction and reflect it in the x axis (2 marks)

24. Triangle

31.1 (5 marks)


25. Probability

$\frac{251}{435}$ (4 marks)

Edit: Corrected error on question 7.

Hello Mr M is the calculater 2015 one?? How is steam an leaf in it? I don't understand if it's paper 2

Why don't you think stem and leaf can appear on a calculator paper? Not every topic on a calc paper requires a calc - most don't.

What was the question for question 3 please?

Ali is y years old.
Bhavara is twice as old as Ali.Ceris is 3 years younger than Ali.The total of their ages is 125 years.Work out the age of each person.

Ali is y years old.

Also, don't suppose you have the method to work out this question do you?

When do the grade boundaries come out for this paper?

Where would I need to go to buy a decent revision guide plz?

where can i find the november and june 2015 papers for all subjects?

when the grade boundaries will be available on the internet??
