Need help with these two problems! 1. use the associative, commutative, and distribute properties to prove the expression 7(3y-5) -2(10+4y) is equivalent to the expression 13y-55.
2. prove algebraically that each expression has the same value by evaluating each expression for y=5, 7(3y-5) -2(10+4y), 13y-55.

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.
