Hospital services Substantially higher wages are paid to hospital employees with no increase in their productivity. C. Miscellaneous Quantity The equations for the demand and supply curves in a certain market are as follows: Demand: Qd =1000-39 P Supply: Qs=30 Solve for equilibrium price and quantity In 1941 the good citizens of Flat Rock, Arizona purchased 1213 three-speed reversible rectocycles at a price of $19.99 each. In 1992 they purchased 2041 at a price of $59.99 each. True or False: These data are inconsistent with the law of downward-sloping demand. Explain your answer to the previous problem. 13.

QUESTION 8 8.1 A bag contains 3 blue marbles and 2 red marbles. A marble is taken from the bag, the colour is recorded and the marble is put aside. A second marble is taken from the bag, the colour is recorded and then put aside. 8.1.1 Draw a tree diagram to represent the information above. Show the probabilities associated with EACH branch, as well as the possible outcomes. (3) 8.1.2 Determine the probability of first taking a red marble and then taking a blue marble, in that order. (2) 8.2 A and B are two events. The probability that event A will occur is 0,4 and the probability that event B will occur is 0,3. The probability that either event A or event B will occur is 0,58. 8.2.1 Are events A and B mutually exclusive? Justify your answer with appropriate calculations. (3) 8.2.2 Are events A and B independent? Justify your answer with appropriate calculations. (3) [11]
