Let X be the amount of time (in minutes) a USPS clerk spends with a customer. It is known that X follows an exponential distribution and USPS clerks take care of 38.1 percent of customers less than two minutes. Find P(0.5 < X < 3).

Solve the system by the elimination method. 2x + y - 4 = 0 2x - y - 4 = 0 when you eliminate y, what is the resulting equation? a. x = 0 b.4x = -8 c.4x = 8

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
