The correct answer is √6-√2/4, or B.

I just took the unit test review and got it correct :)

Find the distance between the points with the given coordinates (-8,-6),(4,10)

Serggg [28]

Hello from MrBillDoesMath!

Answer:

Discussion:

Let (x1,y1) = (-8, -6) and (x2,y2) = (4,10). Per the distance formula,

Distance = sqrt ( (x1-x2)^2 + (y1-y2)^2 ) so

Distance = sqrt ( (-8-4)^2 + (-6-10)^2 )

= sqrt( (12)^2 + (-16)^2 )

= sqrt( 144 + 256 )

= sqrt(400)

= 20

Thank you,

MrB

If x has a continuous uniform distribution on the interval (0,5), what is the 25th percentile for x?

Natasha_Volkova [10]

Given that $X\sim\mathrm{Unif}(0,5)$ , it has PDF

$f_X(x)=\begin{cases}\dfrac15&\text{for }0\le x\l5\\\\0&\text{otherwise}\end{cases}$

and thus CDF

$F_X(x)=\mathbb P(X\le x)=\begin{cases}0&\text{for }x$

The 25th percentile is the value $X=k$ such that $\mathbb P(X\le k)=0.25$ . We have

$\mathbb P(X\le k)=\dfrac k5=0.25\implies k=1.25$
