The work shows the first steps for writing a partial fraction decomposition. StartFraction 4 x cubed minus 5 Over (2 x squared + 1) squared EndFraction = StartFraction A x + B Over (2 x squared + 1) EndFraction + StartFraction C x + D Over (2 x squared + 1) squared EndFraction

4 x cubed minus 5 = (A x + B) (2 x squared + 1) + C x + D. 4 x cubed minus 5 = 2 A x cubed + A x + 2 B x squared + B + C x + D

Which equations can be used in a system of equations to solve for the unknowns. Check all that apply.

A = 0
B = 0
D = –5
A + C = 0
2A + 2B = 4

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.
