For the polynomial below, 3 is a zero. f(x)= x^3-7x^2+9x+9
Express f(x) as a product of linear factors.

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.
