USA Today reported that approximately 25% of all state prison inmates released on parole become repeat offenders while on parole

Zepler [3.9K]

Answer:

$\mu =E(X) = 0*0.207+1*0.367+ 2*0.227+ 3*0.162+ 4*0.036+ 5*0.001= 1.456$

For the variance we need to calculate first the second moment given by:

$E(X) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = 0^2*0.207+1^2*0.367+ 2^2*0.227+ 3^2*0.162+ 4^2*0.036+ 5^2*0.001= 3.33$

And the variance is given by:

$\sigma^2 = E(X^2) - [E(X)]^2 = 3.334 -[1.456]^2 =1.21$

And the deviation is:

$\sigma = \sqrt{1.214} = 1.10$

Step-by-step explanation:

For thi case we have the following distribution given:

X 0 1 2 3 4 5

P(X) 0.207 0.367 0.227 0.162 0.036 0.001

For this case the expected value is given by:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And replacing we got:

$\mu =E(X) = 0*0.207+1*0.367+ 2*0.227+ 3*0.162+ 4*0.036+ 5*0.001= 1.456$

For the variance we need to calculate first the second moment given by:

$E(X) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = 0^2*0.207+1^2*0.367+ 2^2*0.227+ 3^2*0.162+ 4^2*0.036+ 5^2*0.001= 3.33$

And the variance is given by:

$\sigma^2 = E(X^2) - [E(X)]^2 = 3.334 -[1.456]^2 =1.21$

And the deviation is:

$\sigma = \sqrt{1.214} = 1.10$

The surface area of a sphere is decreasing at the constant rate of 3*pi sq. cm/sec . ? At what rate is the volume of the sphere

Eva8 [605]

Surface area of a sphere: $A=4\pi r^2$
Volume of a sphere: $V=\dfrac43\pi r^3$

Differentiate both with respect to an arbitrary variable for time:
$\displaystyle\frac{\mathrm dA}{\mathrm dt}=8\pi r\frac{\mathrm dr}{\mathrm dt}$
$\displaystyle\frac{\mathrm dV}{\mathrm dt}=4\pi r^2\frac{\mathrm dr}{\mathrm dt}$

You're given that $\dfrac{\mathrm dA}{\mathrm dt}=-3\pi$ when $r=2$ , so you can use this in the first equation to solve for $\dfrac{\mathrm dr}{\mathrm dt}$ .

$-3\pi=8\pi \times2\dfrac{\mathrm dr}{\mathrm dt}\implies\dfrac{\mathrm dr}{\mathrm dt}=-\dfrac3{16}$

Now use this to find $\dfrac{\mathrm dV}{\mathrm dt}$ .

$\displaystyle\frac{\mathrm dV}{\mathrm dt}=4\pi \times2^2\times\left(-\dfrac3{16}\right)=-3\pi$
