Problem 2. A random variable has the following density function:

kolbaska11 [484]

If <em>f(x)</em> is a density function, then its integral over the entire real line should be 1:

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2(1-0.5x)\,\mathrm dx=(x-0.25x^2)\bigg|_0^2=2-1=1$

so yes, <em>f(x)</em> is indeed a density function.

The cost of 5 pounds of boudin is $26.What is the constant of proportionality that relates the cost in dollars,y, to the number

Ymorist [56]

Given :

The cost of 5 pounds of boudin is $26.

To Find :

The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .

Solution :

Price per boudin in terms of x and y is :

$P=\dfrac{y}{x}$

Price per boudin by given data :

$P=\dfrac{26}{5}$

So,

$\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x$

Therefore, the constant of proportionality is $\dfrac{26}{5}$ .

Hence, this is the required solution.
