Simplify the expression<br><br> √4x^2/3y<br><br> PLEASE SHOW WORK!!

Dominik [7]

Answer:

$\frac{2 \sqrt{3y} \times |x| }{3y}$

Step-by-step explanation:

$\sqrt{ \frac{ {4x}^{2} }{3y} }$

$\frac{2 \times |x| }{ \sqrt{3y} } \\ \frac{2 \times |x|}{ \sqrt{3y} } \times \frac{ \sqrt{3y} }{ \sqrt{3y} } \\ \frac{2 \times |x| \times \sqrt{3y} }{ \sqrt{3y} \sqrt{3y} }$

$\boxed{Answer:{\boxed{\green{= \frac{2 \sqrt{3y} \times |x| }{3y}}}}}$

Suppose that X ∼ Geom(p) and Y ∼ Geom(r) are independent. Find the probability P (X < Y ).

Murrr4er [49]

$X,Y$ have joint density

$f_{X,Y}(x,y)=f_X(x)f_Y(y)=\begin{cases}pr(1-p)^x(1-r)^y&\text{for }x\ge0,y\ge0\\0&\text{otherwise}\end{cases}$

We can find $P(X$ by integrating the joint density over the region in $\Bbb R^2$ where $x$ in the first quadrant, i.e. above the line $y=x$ : $P(X$

using the fact that

$a^n=e^{n\ln a}\implies\displaystyle\int a^n\,\mathrm dn=\frac1{\ln a}e^{n\ln a}+C=\frac1{\ln a}a^n+C$

Then using the same property,

$P(X$

Find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→1 x2 + 2x −

IrinaK [193]

$f(x)=x^2+2x-3x-1=x^2-x-1\\\\\lim\limits_{x\to1}(x^2-x-1)=1^2-1-1=-1$
