Suppose that 40% of all u. s. employees contribute to a retirement plan (p = 0.40). (a) in a random sample of 100 employees, what is the approximate probability that at least half of those in the sample contribute to a retirement plan? (round your answer to four decimal places.)

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
