the cost that a carpet cleaning company charges is directly proportional to the number of rooms cleaned. the cost is $22 for each room.
(a) write a direct variation equation to represent the cost.
(b) how many rooms can a hotel pay the company to clean for $200? write and solve an equation.
(c) suppose the hotel plans to tip the carpet cleaners $40, how many rooms can the hotel get cleaned for $200 now? write and solve an equation.

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
