Problem 4) A company that manufactures video cameras produces a basic model, intermediate model, and deluxe model. Over the past year, 40% of the cameras sold have been the basic model, 35% have been intermediate model, and 25% have been deluxe model. Of those buying the basic model, 95% purchased an extended warranty, of those buying the intermediate model 60% purchased an extended warranty, and of those buying the deluxe model 10% purchased an extended warranty. a) What is the probability that a randomly selected purchaser has an extended Warranty

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
