Decide whether the two events are disjoint and tell why or why not:
• randomly choosing a scarf that is blue
• randomly choosing a scarf that is frayed
A: Not disjoint, because the events cannot occur at the same time.
B: Disjoint, because the events cannot occur at the same time.
C: Disjoint, because the events can occur at the same time.
D: Not disjoint, because the events can occur at the same time.

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?

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) = .
