Los dueños de un restaurante cultivan sus propios

zzz [600]

Answer:

Quedan 2.083 m^3 de agua en el reservorio.

Equivalen a 2083 litros.

Step-by-step explanation:

Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.

Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).

Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:

$V=(1/3)\cdot V_0=(1/3)\cdot6.25\,m^3=2.083\,m^3$

Este valor equivale a un volumen en litros de:

$V=2.083\,m^3\cdot \dfrac{1,000\,l}{1m^3}=2,083\,l$

Find the z-scores for which 8% of the distribution's area lies between minus−z and z.

Troyanec [42]

$\mathbb P(-z$

Because the distribution (normal) is symmetric, you know that $\mathbb P(Zz)$ , so

$\mathbb P(Zz)=2\mathbb P(Z$

Now,

$\mathbb P(-z$
$\implies\mathbb P(Z$

If $F_Z(z)$ is the CDF of the normal distribution, so that $F_Z(z)=\mathbb P(Z$ , then the z-score satisfies

$\begin{cases}z={F_Z}^{-1}(0.54)\\z=-{F_Z}^{-1}(0.46)\end{cases}$

so that $z\approx0.1004$ .
