Suppose u1, u2, ..., un are independent random variables and for every i = 1, ..., n, ui has a uniform distribution over [0, 1].

sattari [20]

$Z=U_{(1)}=\min\{U_1,\ldots,U_n\}$

has CDF

$F_Z(z)=1-(1-F_{U_i}(z))^n$

where $F_{U_i}(u_i)$ is the CDF of $U_i$ . Since $U_i$ are iid. with the standard uniform distribution, we have

$F_{U_i}(u_i)=\begin{cases}0&\text{for }u_i$

and so

$F_Z(z)=1-(1-F_{U_i}(z))^n=\begin{cases}0&\text{for }z$

Differentiate the CDF with respect to $z$ to obtain the PDF:

$f_Z(z)=\dfrac{\mathrm dF_Z(z)}{\mathrm dz}=\begin{cases}n(1-z)^{n-1}&\text{for }0$

i.e. $Z$ has a Beta distribution $\beta(1,n)$ .

in jacks class, 18 of the students are y'all and 10 are short. in Michael class 54 students are tall and 30 students are short w

Naddik [55]

Answer:

The answer is: both class have the same ratio.

Step-by-step explanation:

Get the ratio of tall to short. Divide Tall by Short:

Jack's class:

18/10 = 1.8 tall one for every short one

Michael's class:

54/30 = 1.8

The ratio is the same!

You can further prove this by multiplying 18 times 3 and getting 54, and 10 times 3 and getting 30.

Hope this Helps!! Have an Awesome Day!! (-:
