- 1Expanding and Factorising2 marks
Expand and simplify 2(8x - 1).
- 2Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 9, y = 36. Work out y when x = 2.
- 3Similar Shapes (Area and Volume)3 marks
Two similar shapes have lengths in the ratio 1 : 2. The smaller has an area of 10 cm^2. Work out the area of the larger.
- 4Probability (Higher)3 marks
A biased coin lands on heads with probability 0.25. It is thrown 50 times. How many heads would you expect?
- 5Scatter Graphs3 marks
A line of best fit on a scatter graph has equation y = 7x + 20. Use it to estimate y when x = 2.
