Let g be a connected, weighted graph, let v be a vertex in g, suppose that the weights of the edges incident on v are distinct let e be the edge of minimum weight incident on v must e be contained in every minimum spanning tree?

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
