Given the following message and carrier equations, determine the AM modulated signal equation: m(t)=3cos(2π4kHz*t), c(t)=2cos(2π3MHz*t) a. s(t)=3[1 + 0.67cos(2π4000t)]cos(2π3E6t) b. s(t)=2[1 + 1.5cos(2π4000t)]cos(2π3E6t) c. s(t)=3[1 + 0.67cos(2π3E6t)]cos(2π4kHz*t) d. s(t)=2[1 + 1.5cos(2π3MHz*t)]cos(2π4000t)

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.

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).

An alternative to car buying is to make monthly payments for a period of time, and then return the vehicle to the dealer, or purchase it. this is called
