(a) Construct the cumulative frequency table.
(b) Draw the cumulative frequency curve.
(c) From the curve, estimate the:
(i) median;
(ii) semiinterquartile range;
(iii) probability that a participant chosen at random weighs at least 60 kg.
5. Using ruler and a pair of compasses only,
(a) construct a rhombus PQRS of side 7 cm and ÐPQR = 60o;
(b) locate point X such that X lies on the locus of points equidistant from PQ and QR and also equidistant from Q and R;
(c) measure /XR/.
6. (a) The area of trapezium PQRS is 60 cm2. PQ//RS, /PQ/ = 15 cm, /RS/ = 25 cm and ÐPSR = 30o. Calculate the :
i) Perpendicular height of PQRS;
ii) PS.
(b) Ade received 3/5 of a sum of money, Nelly 1/3 of the remainder while Austin took the rest. If Austin’s share is greater than Nelly’s share by N3000, how much was did Ade receive?
7. (a) P varies directly as Q and inversely as the square of R. If P = 1 when Q = 8 and R = 2, find the value of Q when P = 3 and R = 5.
(b) An aeroplane flies from town A(20oN, 60oE) to town B(20oN, 20oE).
(i) If the journey takes 6 hours, calculate, correct to 3 significant figures, the average speed of the aeroplane.
(ii) If it then flies due north from town B to town C, 420 km away, calculate, correct to the nearest degree, the latitude of town C.
[Take radius of the earth = 6400 km and π = 3.142]
8. Two fair dice are thrown.

(a) Write out the elements of M and N.
(b) Find the probability of M or N.
(c) Are M and N mutually exclusive? Give reasons.
9. A library received a $1,300 grant. It spends 10% of the grant on magazine subscriptions, 35% on new books, 15% to repair damaged books, 30% to buy new furniture and 10% to train library staff.
(a) Represent this information on a pie chart.
(b) Calculate, correct to the nearest whole number, the percentage increase of the amount for buying new books over that of new furniture.
10. A sector of a circle with radius 21 cm has an area of 280 cm2.
(a) Calculate, correct to 1 decimal place, the perimeter of the sector.
(b) If the sector is bent such that its straight edges coincide to form a cone, calculate, correct to the nearest degree, the vertical angle of the cone. [Take π = 22/7 ]
