Supposef(1) = 72 - 1 - 12, g(x) = 2 + 3, andh(x) = 6x - 1. Which of the following function operations are correct? Select three that apply. ОА
(f + g)(x) = 1-4
(f - h)(u) = - 72 - 13
Dc (g* h)(x) = 6x2 + 17x - 3
OD (g- h)(x) = 52 - 4
OE (h+ f)(x) = x2 + 5x - 13

If x=-3 is the only x-intercept of the graph of a quadratic equation, which statement best discribes the discriminant of the equation?

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

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.
