Let X denote the amount of time a book on two-hour reserve is actually checked out, and suppose the cdf is the following.

0 , x<0

f(x) = ((x^2)/4) , 0 <= x <= 2

1 , 2<= x

Use the cdf to obtain the following. (If necessary, round your answer to four decimal places.)

(a) P(X %u2264 1)

(b) P(0.5 %u2264 X %u2264 1)

(c) P(X > 1.5)

(d) The median checkout duration [solve 0.5 = F(mew)]

(e) Use F'(x) to obtain the density function f(x)
(f) Calculate E(X)

(g) Calculate V(X) and %u03C3x
(h) If the borrower is charged an amount h(X) = X2 when checkout duration is X, compute the expected charge

E[h(X)].

The author's diction and characterization indicates the authores purpose because the word choice they decide to use gives you a realistic image of inmmigration. The way he shows the characters is in a sequence of different thigs that Enrique goes through in life. For example, when Enrique's mother left them, the author shows how other people helped Enrique during that time in his story. The author showed how his grandmother took him in and loved him like a mother.
