Find the value of the trigonometric function when t is replaced by - t: 1) tan t= sqrt3/3
2) sin t= -1/2
3) cos t= -1
4) sin t= 1

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.
