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.)

Determine which postulate or theorem can be used to prove that lmn =nmo

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m
