Let the random variable x be equally likely to assume any of the values 1/10, 1/5, or 3/10. determine the mean and variance of x

Keith_Richards [23]

Since the values are equally likely and equally spaced, their mean is the middle one.
the mean is 1/5

The variance is the average of the square of the deviations from the mean.
σ² = (1/3)((-1/10)² + 0² + (1/10)²) = 2/300
the variance is 2/300

Una comercializadora de café necesita construir una bodega con forma de cubo. La capacidad de la bodega debe ser de 216 metros c

Alexus [3.1K]

Answer:

La arista de la bodega debe medir 6 metros.

Step-by-step explanation:

Podemos encontrar la arista de la bodega sabiendo su volumen:

$V = a^{3}$

En donde:

V: es el volumen de un cubo = 216 m³

a: es la arista del cubo =?

La arista del cubo es:

$a = \sqrt[3]{V} = \sqrt[3]{216 m^{3}} = 6 m$

Por lo tanto, la arista de la bodega debe medir 6 metros.

Espero que te sea de utilidad!
