Atelephone company charges a fixed monthly rate plus a rate per minute of usage. the company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. an equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). which of the following best describes the steps to draw the graph of y against x?
draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6
draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67
draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67

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.
