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 \\

Determine whether the quadratic function show below has a minimum or maximum then determine the minimum or maximum value of the
REY [17]

Answer:

The quadratic has a minimum value.

The minimum value is at (3, 2).

Step-by-step explanation:

We are given the quadratic function:

f(x)=3x^2-18x+29

First, since the leading coefficient is positive, this quadratic function will be concave up.

Hence, we will have a minimum value.

The minimum or maximum value is the vertex of the quadratic. The vertex is given by:

\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)

In this case, a = 3, b = -18, and c = 29. Thus, the x-coordinate of the vertex is:

\displaystyle x=-\frac{-18}{2(3)}=\frac{18}{6}=3

And the minimum value is:

f(3)=3(3)^2-18(3)+29=2
