Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Simplify (1/2)4th power a. (1/16) b.(1/8) c.(1/4)
