Two components of a minicomputer have the following joint pdf for their useful lifetimes X and Y: f(x, y) = xe−x(1 + y) x ≥ 0 an
Yuri [45]

Answer:

For the given explanation we see that two life times are not independent

Step-by-step explanation:

probability for X (for x≥ 0)

\int\limits^\infty_0 {xe^-^x^(^1^+^y^)} \, dy

-e^-^x\int\limits^\infty_0 {de^-^x^y} \,

e⁻ˣ

Probability for X exceed 3

= \int\limits^\infty_3 {f(x)dx

= \int\limits^\infty_3 {e^-^3 dx

= e^-^3

probabilty for y≥ 0 is

\int\limits^\infty_0 {xe^-^x^(^1^+^y^)} \, dx \\

\int\limits^\infty_0{-x/1+yd(e^-^x^(^1^+^y^))} \, =1/(1+y)² \\

Write the letter for each expression in the box under the correct category in the table.
Ad libitum [116K]

Answer:

a) 9+(-3) + (-2)  = 9 -5 = 4> 0  ⇒  Positive Sum

b) -12 +1 +11  = -12  +12 5 =  0  ⇒  Zero Sum

c) -3 +8 + (-4)  = -7 + 8 -5 =-1 <  0  ⇒ Negative Sum

d)  -4+9+(-10) = 9 -14 = -5 <  0  ⇒ Negative Sum

e) 3+(-2) + (-4)  = 3  -6= -3 <  0  ⇒ Negative Sum

f) 2 + (-4) + 2  = 4 -4 =  0  ⇒  Zero Sum

Step-by-step explanation:

Positive Sum is defined as the condition in which the Sum of total of gains and losses is GREATER THAN ZERO.

Zero Sum  is defined as the condition in which the Sum of total of gains and losses is EQUAL TO ZERO.

Negative Sum is defined as the condition in which the Sum of total of gains and losses is LESS THAN ZERO.

Now, here

a) 9+(-3) + (-2)  = 9 -5 = 4> 0  ⇒  Positive Sum

b) -12 +1 +11  = -12  +12 5 =  0  ⇒  Zero Sum

c) -3 +8 + (-4)  = -7 + 8 -5 =-1 <  0  ⇒ Negative Sum

d)  -4+9+(-10) = 9 -14 = -5 <  0  ⇒ Negative Sum

e) 3+(-2) + (-4)  = 3  -6= -3 <  0  ⇒ Negative Sum

f) 2 + (-4) + 2  = 4 -4 =  0  ⇒  Zero Sum

The polynomial p(x) = 2x^3+17x^2+41x+30 has a known factor of (x+5)
Assoli18 [71]

Answer:

2x³ + 17x² + 41x + 30 =  (x + 5) (x + 2) (2x + 3)

Step-by-step explanation:

2x³ + 17x² + 41x + 30 = (x + 5) (2x² + ax + 6) =

2x³ + (a + 10) x² + (5a + 6) x + 30

a + 10 = 17         a = 7   ( check: 5a + 6 = 5 x 7 + 6 = 41)

2x³ + 17x² + 41x + 30 = (x + 5) (2x² + 7x + 6) = (x + 5) (x + 2) (2x + 3)
