Does the point (3, 12) satisfy y > 3x - 2?
- 2Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 7, y = 63. Work out y when x = 8.
- 3Transformations2 marks
The point (5, -5) is rotated 90° clockwise about the origin. Write down the coordinates of the image.
- 4Probability (Higher)3 marks
A biased coin lands on heads with probability 0.15. It is thrown 50 times. How many heads would you expect?
- 5Averages from Frequency Tables2 marks
Grouped data has five classes of width 10, the first being 10 < x <= 20. The frequencies in order are 21, 16, 7, 11, 3. Write down the modal class.
