Study the flow chart below Perform a dry run for the flow chart. State the purpose of the flow chart. (5 marks) An elastic string of natural length 60cm is stretched to 70cm by a stone of mass 1.5kg hanging on it. Find the, modulus of elasticity of the string. energy stored in the stretched string at equilibrium. (5 marks) The probability that Blessing goes for work using a taxi is and her probability of arriving early for work when she use a taxi is. If she uses a private means, her chance of arriving late is. What is the probability that that she arrives early for work on a given day. If she arrives early, what is the probability that she used a private mean? (5 marks) SECTION B (60 MARKS) Attempt any five questions A continuous random variable R has a probability density function (pdf), f(r) shown graphically below Find the, value of k expression of the pdf, f(r) determine the distribution function (c.d.f) of R and sketch it. Calculate (12 marks) Two cars A and B are proceeding one on each road, towards the point of intersection of two roads which meet at an angle of 600. If the speeds of A and B are and and are 70m and 40m respectively from the cross road, and the cars maintain their speeds, determine the speed of B relative to A. time when they are nearest to each other. the distance of B from the cross road when they are nearest to each other.
