The image you uploaded appears to show the graph of a cumulative distribution function (CDF) for a continuous random variable. From the graph, it seems to start at a value of 0 for $F(x)$ when $x$ is less than 0, increases linearly between 0 and 5, and reaches a value of 1 when $x$ is greater than 5.

To calculate the expected value (mathematical expectation) of the continuous random variable $X$, we use the formula for the expected value:

$E(X) = \int_{-\infty}^{\infty} x f(x) \, dx$

Where $f(x)$ is the probability density function (PDF), which is the derivative of the cumulative distribution function $F(x)$.

From the graph, it appears that the CDF has a linear form between 0 and 5. Thus, the PDF, $f(x)$, will be constant over this interval.

Do you want me to compute the expected value in more detail? Would you like me to go through the steps explicitly?
