Every sheet in February 1975
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st February 1975Prove that the sum of 4 consecutive integers is always a multiple of 2. State the simplified sum you would use.
- 2nd February 1975y is directly proportional to x^3. When x = 2, y = 32. Work out y when x = 3.
- 3rd February 1975In a vector proof you find that vector PQ = 2a + 5b and vector RS = 4a + 10b. What does this show about PQ and RS?
- 4th February 1975A bag holds 2 red and n blue counters. The probability of taking a red is 2/9. Work out n.
- 5th February 1975A histogram has two bars: one 10 units wide with frequency density 2, one 10 units wide with density 0.8. How many values in total?
- 6th February 1975Simplify sqrt(18) + sqrt(8), giving your answer in the form a sqrt(b).
- 7th February 1975f(x) = 6x + 4 and g(x) = 3x + 3. Work out fg(-2).
- 8th February 1975y is directly proportional to sqrt(x). When x = 4, y = 16. Work out y when x = 9.
- 9th February 1975A cuboid measures 14 cm by 13 cm by 11 cm. Work out the length of the longest diagonal inside it, to 1 decimal place.
- 10th February 1975A bag holds 5 red and 5 blue counters. Two are taken without replacement. Given the first was red, what is the probability the second is blue?

- 16th February 1975A bag holds 5 red, 3 blue and 3 green counters. Two are taken without replacement. Given neither is green, what is the probability both are red?
- 17th February 1975A histogram has two bars: one 10 units wide with frequency density 1.2, one 10 units wide with density 0.8. How many values in total?
- 18th February 1975Expand and simplify (7 + sqrt(10))(7 - sqrt(10)).
