- 1Expanding and Factorising Quadratics3 marks
Factorise x^2 - 8x + 7.
- 2Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 6, y = 72. Work out y when x = 9.
- 3The Sine Rule3 marks
In triangle ABC, angle A is 44°, angle B is 42° and side a is 10 cm. Use the sine rule to work out side b, to 1 decimal place.
- 4Venn Diagrams3 marks
In a Venn diagram, 8 are in A only, 9 in B only, 3 in both and 8 in neither. Work out the probability a random one is in both.
