Ihate fractions, need with this. 1a. consider the rational numbers -2/5 and -1/2. what rational number is halfway between those numbers? 1b. arrange -2/5, -1/2, and the answer to part ( a ) in increasing order.

Given the function f(x) = 3x + 1, evaluate f(a + 1). a. 3a + 1 b. a + 2 c. 3a + 4

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.

Icould really use some with this question.
