An example of dependent events is drawing a blue marble out of one jar and then drawing a
Karo-lina-s [1.5K]

<u>Answer:</u>

A red marble out of the same jar, without replacing the first marble.

<u>Step-by-step explanation:</u>

Dependent events are those which involve a first event which affects the outcome of the second event.

This means that the probability of the second event changes because of the occurrence of the first event.

So if a blue marble is drawn out of one jar, then drawing a red marble out of the same jar, without replacing the first marble would be an example of dependent events.

This box can be packed with 48 units cubes. The edge length of each unit cube is 1 meter. What is the volume of the box?
Dafna1 [17]

48 m³

Step-by-step explanation:

A cube has equal length width and height

A cube in this case has length 1m meaning the width and height are also 1 m each in length.

The volume of the cube is (L * W * H) =  1 * 1 * 1 = 1 m³

If 48 of these can fit in the bigger box, then the bigger box has the volume of;

48 * 1 m³ = 48 m³

Ayuda, no le entiendo :)
Dmitry [639]

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.

<h3>¿Cuántos dias tardarán en fabricar 3000 ruedas si trabajan 10 horas diarias?</h3>

Sabemos que trabajando 8 horas, en 5 dias producen 2000 ruedas.

El número total de horas que trabajan en esos 5 dias es:

(8 horas)*5 = 40 horas

Entonces se producen 2000 ruedas en 40 horas, es decir, la razon de trabajo es:

(2000 ruedas)/(40 horas) = 50 ruedas por hora.

Ahora, sí en la fabrica trabajan 10 horas al día, entonces van a producir:

10h*(50 ruedas por hora) = 500 ruedas por día.

El número x de días que deben trabajar para producir 3000 ruedas es:

x*(500 ruedas por dia) = 3000 ruedas

x = (3000 ruedas)/(500 ruedas por dia) = 6 dias.

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.
