- 1Inequalities on Graphs3 marks
Does the point (2, -21) satisfy y > -4x - 6?
- 2Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 5, y = 25. Work out y when x = 11.
- 3Transformations2 marks
The point (8, -4) is rotated 90° anticlockwise about the origin. Write down the coordinates of the image.
- 4Probability (Higher)3 marks
A biased coin lands on heads with probability 0.1. It is thrown 100 times. How many heads would you expect?
- 5Averages from Frequency Tables2 marks
Grouped data has five classes of width 10, the first being 40 < x <= 50. The frequencies in order are 7, 21, 16, 3, 11. Write down the modal class.
