katrin [286]

Using the average daily balance method, the amount to be used in calculating Theresa's interest is given by:

$\frac{350\times12+520\times19}{12+19} = \frac{4200+9880}{31} \\ \\ = \frac{14080}{31} =$454.19$

Therefore, the interest charge on Theresa for the biling cycle is given by:

$\frac{454.19(0.14)}{12} = \frac{63.59}{12} \\ \\ =\$5.30$

Suppose that the probabilities of a customer purchasing 0, 1, or 2 books at a book store are 0.4, 0.2, and 0.4, respectively

Volgvan

Answer:

Expected number of books = 1.0

Step-by-step explanation:

Expected number of books, E(x) = ∑xp(x)

∑ = Summation

x = books

p(x) = probability of purchasing a book

E(x) = (0*0.4) + (1*0.2) + (2*0.4)

E(x) = 0 + 0.2 + 0.8 = 1.0
