Every sheet in October 1982
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st October 1982A bag holds 5 red and 4 blue counters. Two are taken without replacement. Given the first was red, what is the probability the second is blue?
- 2nd October 1982A histogram has two bars: one 10 units wide with frequency density 2.5, one 20 units wide with density 0.6. How many values in total?
- 3rd October 1982x = 61 and y = 8, each correct to the nearest whole number. Work out the upper bound of x - y.
- 4th October 1982In an algebraic proof, how would you write the next odd number after 2n + 1 in terms of an integer n?
- 5th October 1982y is inversely proportional to x^2. When x = 4, y = 12. Work out y when x = 2.
- 6th October 1982A cuboid measures 13 cm by 5 cm by 13 cm tall. Work out the angle between its longest internal diagonal and the base, to 1 decimal place.
- 7th October 1982A bag holds 4 red, 5 blue and 3 green counters. Two are taken without replacement. Given neither is green, what is the probability both are red?
- 8th October 1982On a histogram, a 4-wide bar and a 8-wide bar have the same frequency density of 3. How many more values are in the wider class?
- 9th October 1982A car covers 730 m (to the nearest 10 m) in 7 s (to the nearest second). Work out the lower bound of its speed, to 2 decimal places.
- 10th October 1982Make x the subject of 3x + 8 = y(x + 8).
- 11th October 1982y is directly proportional to x^3. When x = 2, y = 40. Work out y when x = 4.
- 12th October 1982The point (20, 21) lies on the circle x^2 + y^2 = 841. Work out the gradient of the tangent to the circle at that point.
- 13th October 1982A bag holds 8 counters, r of them red. Two are taken without replacement and P(both red) = 1/28. Work out r.
- 14th October 1982A histogram has two bars: one 5 units wide with frequency density 2.5, one 20 units wide with density 1.4. How many values in total?
- 15th October 1982Rationalise the denominator of 55/sqrt(5), giving your answer in its simplest form.
- 16th October 1982Write 5/(x + 1) + 6/(x + 2) as a single fraction.
- 17th October 1982y is directly proportional to sqrt(x). When x = 49, y = 14. Work out y when x = 4.
- 18th October 1982In a circle theorem proof, a step uses the fact that opposite angles of a cyclic quadrilateral are being proved. State the reason being quoted.
- 19th October 1982The probability of winning a game is 3/5. A player expects 6 wins. How many games did they play?
- 20th October 1982On a histogram, a 4-wide bar and a 8-wide bar have the same frequency density of 1.5. How many more values are in the wider class?
- 21st October 1982Simplify sqrt(48) + sqrt(108), giving your answer in the form a sqrt(b).
- 22nd October 1982Solve 5x^2 + 9x + 4 = 0.
- 23rd October 1982A train slows steadily from 26 m/s to rest in 8 seconds. Work out its deceleration.
- 24th October 1982In a vector proof you find that vector PQ = a + b and vector RS = 5a + 5b. What does this show about PQ and RS?
- 25th October 1982A bag holds 4 red and n blue counters. The probability of taking a red is 4/7. Work out n.
- 26th October 1982A histogram has two bars: one 20 units wide with frequency density 0.4, one 5 units wide with density 1.4. How many values in total?
- 27th October 1982A rectangle is 5 cm by 29 cm, each correct to the nearest cm. Work out the upper bound of its area.
- 28th October 1982f(x) = 6x - 11. Work out the inverse function f^-1(x).
- 29th October 1982y is inversely proportional to x^2. When x = 3, y = 4. Work out y when x = 2.
