Three strips of 2 yard wide outdoor carpet are used to cover a sidewalk. one is 3.5 yards long, the second is 25% longer than the first, and the third is 6 1/4 yard longer. how long are the 3 carpets end to end

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.
