Answer:

Y=3x+5

Step-by-step explanation:

If we take x = 1, according to the first function (the answer) y would be 8.

Other options:

—————

Formula 3:

Y= 2^x+5 == 7

Formula 4:

Y = x+8 == 9

True answer = 10.

——————

Ok, so the last one seems more accurate lets test the first and last one on two more numbers:

——————

X = 15

Formula 1:

50

Formula 4:

23

True answer = 60.

The first formula wins.

————————-

X= 10

Formula 1:

35

Formula 4:

18

True answer = 41

The first formula wins.

——————

So, we can see that the first formula is most accurate.

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).
