Let f(x) = xe−x if x ≥ 0 and f(x) = 0 if x < 0<br> Is f a probability density function?

Lynna [10]

Yes. $f(x)$ is a PDF if

• $f(x) \ge 0$ for all $x$ in the support; this is true, since $e^{-x}>0$ for all $x$ , and multiplying a positive number $x$ doesn't change this fact;

• the integral of $f(x)$ over its support is 1; this is also true, since

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = \int_0^\infty xe^{-x} \, dx = 1$

which can be computed by parts.

lianna [129]

Answer: P(5A) = 0

Step-by-step explanation:

There are four aces in total in a 52 card deck. Therefore the probability of getting 5 aces can be expressed as;

P(5A) = 4/52 × 3/51 × 2/50 × 1/49 × 0/48 = 0

Therefore, it is impossible to get 5 aces from a standard 52 cards deck

How do you graph the equation Y = 4x + 2 and 4x - 3y = 12?

Pachacha [2.7K]

Answer:look below

Step-by-step explanation:

To graph y= 4x +2 plot the point (0,2) on the graph because the y-intercept is 2 then use the slope: 4 to find another point. Another point would be (1,6).
