A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.28 lb, the mean of all of the weights is x overbarequals2.219 lb, and the standard deviation of the weights is sequals1.825 lb. a. What is the difference between the weight of 5.28 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.28 lb to a z score. d. If we consider weights that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the weight of 5.28 lb significant? a. The difference is nothing lb.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
