34. (a) The table below shows the distribution of the scores obtained by 120 shooters in a shooting competition. Using a graph sheet, draw an ogive for the distribution. Scores obtained Number of shooters 0 - 10 5 10 - 20 9 20 - 30 16 30 - 40 22 40 - 50 26 50 - 60 18 60 - 70 11 70 - 80 6 80 - 90 4 90 - 100 3 Use your ogive to estimate:- (i) The Median   35. (ii) The inter quartile range   36. (iii) The number of shooters who obtained more than 75% scores.   37. (b) In the given figure, ABC is a triangle. DE is parallel to BC and AD/DB = 3/2. (i) Determine the ratios AD/AB, DE/BC  (Type in the answers separated by commas. Leave no spaces around the commas and the : (colon) symbol.)   38. (ii) Prove that ΔDEF is similar to ΔCBF. Hence, find EF/FB   39. (iii) What is the ratio of the areas of ΔDFE and ΔBFC?
