3/5x-21 is the answer(I think) if not it’s 21-3/5x

The equation of a line is x 3y = 14. what is the y-intercept of the line? −14 3/14 14 14/3

Olin [163]

X+3y = 14
3y = -x +14
y = -1/3 x +14/3
so the y intercept is 14/3

Guys help me please I need this in September 27,2018

Okay so first off first off I believe 4-6 is linear because it is increasing at a steady rate and 7 is exponential because it has a constant rate of growth. I’m not 100% I’m correct on that. 8 is linear, 9 is exponential.
For 4: f(x)=-1/2x + 1
5: f(x)=-2x +4
That’s all I know right now. I hope it helps a little bit

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

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

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