If an arrow is shot upward on mars with a speed of 54 m/s, its height in meters t seconds later is given by
y = 54t − 1.86t2.
(round your answers to two decimal places.)
(a) find the average speed over the given time intervals.
(i) [1, 2]
m/s

(ii) [1, 1.5]
m/s

(iii) [1, 1.1]
m/s

(iv) [1, 1.01]
m/s

(v) [1, 1.001]
m/s

(b) estimate the speed when t = 1.
m/s

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.
