For the ques 2 there is really not much to do
a) just complete the table
b) draw the graph
c) give the values of x when y = 0
d) divide the graph into 2 equal halves (which would be from its max or min point)

For ques 5
a)i) count the number of times the specific number comes and write it down
ii) write down the mode
iii) add 1 to the sum of the frequency, next divide the answer by 2. This will give the position and find the median
iv) divide the sum of data by the sum of the frequency

b)i) add the frequencies of every bar
ii) sigma fx / sigma f

Okay sorry had to go...........anyways here:
a) just write down the angle in the form 0....
b) i) draw an angle towards the left side of (360-350) 10 of more than 3 cm that is a long one
ii) the ship S would be where the above line intersects AC
c)i) just measure
ii) this is like the map scales................ 7cm: 14 km
1cm: 2 km
1:200000
d) i) draw a circle with radius 5 cm as per the scale above centre A
ii) connect S and R; just measure the line that would be inside the circle
e)i) measure the line BR
ii) divide 40 by 60; then divide the above distance by the answer
iii) divide e(ii) by 1.85
