Suppose that the joint probability density function of ˜ (X, Y) is given by:´

f X,Y (x,y) = 4x/y3 I(0.1)(x), I (1, ∞)(y).

Calculate

a) P(1/2 < X < 3/4, 0 < Y ≤ 1/3).

b) P(Y > 5).

c) P(Y > X).

For each call to the following method, indicate what console output is produced:

public void mystery2(int n) {
    if (n <= 1) {
        System.out.print(n);
    } else {
        mystery2(n / 2);
        System.out.print(", " + n);
    }
}

(define (count-leaves t)
(cond ((null? t) 0)
((not (pair? t)) 1)
(else (+ (count-leaves (car t))
(count-leaves (cdr t))))))

Trace this function with the example:

For example, (count-leaves '((4 5 6) (1 2) () (3) )) returns 6

1. Explain M&M proposition 1

2. What is Profitability Index and its pros and cons?

3. What is Payback Period? And its pros and cons?

Differentiate: do the Derivative for all

(a) f(x) = x ^3 − 5e + x ^5/3

(b) g(x) = x ^2+e^ x / √ x+1

(c) h(x) = 2^sec(x)

(d) j(x) = cos(sin(xe^x ))

(e) f(x) = 2^x sin−1 (x^3 )

(f) g(x) = x ^sec(x)

(g) f(x) = tan−1 ( √ 2x + 1)

(h) h(x) = e^x log3 (x^2 − 1)

(i) g(x) = (cot(x) + 4/ x )(ln(x) − 2e^ x )

(j) j(x) = log2 (sin(xe^x ))

(k) h(x) = √ x ^x

Polar Covalent, Covalen or Ionic? What are each of their electronegative charges?

Q: My A:

1. ) K-O Ionic? 4.0(K)-2.0(O)= 2

2.) H-C Covalent 1.0(H)-1(C)=0

3.) S-C Covalent 3(S)-1(C)=2

4.) O-C Covalent 2(O)-1(C)=1

This is how I did it but its not correct as I am seeing in my textbook the numbers have decimals, for example:

NaCl 3.0 (Cl)-0.9(Na)=2.1 Ionic

Where does the 3.0 and 0.9 # come from? I though it was taking the period it was in and that representing the number as you can see in the breakdown above that is probably wrong.

Thank you!
