Prove that every graph containing only even vertices is bridgeless. (an even vertex is a vertex of even degree.)

Can you divide 25 into 4 equal groups? explain why or why not.

E. which of the following is not a possible probability? a. 25/100 b. 1.25 c. 1 d. 0

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.
