Step-by-step explanation:

The pdf of X is given by 3e^x(1-e^-2y). Please check the screenshot for the workings.

The pdf of Y is given by 6e^-2y. Please check the screenshot for the workings.

The expected time the device fails is the expected time Y fails, so we are going to find the expected time of Y which equals to 0.83.

Write an equation of the line that passes through the given points.<br> (-2,5) and (1,2)

Anon25 [30]

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{2}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{2}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{(-2)}}}\implies \cfrac{-3}{1+2}\implies \cfrac{-3}{3}\implies -1$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5}=\stackrel{m}{-1}[x-\stackrel{x_1}{(-2)}] \\\\\\ y-5=-(x+2)\implies y-5=-x-2\implies y=-x+3$

Four friends order sandwiches for $15, a bottle of juice for $4 and a box of cookies for $3. The friends want to evenly split th

Gelneren [198K]

First, let’s figure out the total amount of money

$15 + $4 + $3 = $22

Okay, so now we know the total amount of money spent, so we can divide

22 ÷ 4 = 5.5

5.5 = $5.50

Here are the expressions:

(15 + 4 + 3) ÷ 22 = 5.5

22 ÷ 4 = 5.5 (or 5.50)

Therefore, each friend owes $5.50

Hope this helps you
