Nick’s pond was stocked with 50 fish and an additional 5 fish are added each week. Mark’s pond was stocked with 15 fish and an additional 10 fish are added each week. Assuming no fish die or are removed, in how many weeks will Mark’s pond have more fish in it than Nick’s?

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.
