Suppose X,Y,and C represent the length, width, and perimeter of a flat rectangular sheet metal part. Note that Xis a normal random variable having a mean of 15 cm and a standard deviation of 1 cm, and Y is independent of X and normally distributed with a mean of 25 cm and a standard deviation of 2 cm. Determine the following.

(a) the expected value of the perimeter

(b) the standard deviation of the perimeter

(d) the perimeter that is exceeded by 99% of the sheet metal parts
