(a) Copy and complete the table of values for the relation \(y = 2 \sin x + 1\)

(b) Using scales of 2 cm to 30° on  the x- axis and 2 cm to 1 unit on the y- axis, draw the graph of \(y = 2 \sin x + 1, 0° \leq x \leq 270°\).

(c) Use the graph to find the values of x for which \(\sin x = \frac{1}{4}\).

(a) Copy and complete the following table for multiplication modulo 11.

Use the table to : (i) evaluate \((9 \otimes 5) \otimes (10 \otimes 10)\);

(ii) find the truth set of :(1) \(10 \otimes m = 2\);  (2) \(n \otimes n = 4\)

(b) When a fraction is reduced to its lowest term, it is equal to \(\frac{3}{4}\). The numerator of the fraction when doubled would be 34 greater than the denominator. Find the fraction.

(a) 

In the Venn diagram, P, Qand R are subsets of the universal set U. If n(U) = 125, find : (i) the value of x ; (ii) n(\(P \cup Q \cap R'\)).

(b)  In the diagram, O is the centre of the circle. If WX is parallel to YZ and < WXY = 50°, find the value of (i) , WYZ 

(ii) < YEZ.

(a) Solve : \((x - 2)(x - 3) = 12\).

(b)  In the diagram, M and N are the centres of two circles of equal radii 7cm. The circle intercept at P and Q. If < PMQ = < PNQ = 60°, calculate, correct to the nearest whole number, the area of the shaded portion. [Take \(\pi = \frac{22}{7}\)].

The table shows the distribution of outcomes when a die is thrown 50 times. Calculate the : 

(a) Mean deviation of the distribution ; (b) probability that a score selected at random is at least a 4.
