Un camión traslada 12 vehículos. Algunos son autos y otros son camionetas. Cada auto tiene una masa de 2 toneladas y cada camion

bagirrra123 [75]

Encontrando y resolviendo un sistema de ecuaciones, veremos que hay 9 camionetas y 3 autos.

Sabemos que hay 12 vehículos en el camión.

Definamos:

a = número de autos
c = número de camionetas.

tal que a + c = 12

La masa total será:

a*2 ton + c*3 ton

Y sabemos que el camión lleva 33 toneladas, entonces tenemos:

a*2 ton + c*3 ton = 33 ton

Así encontramos el sistema de ecuaciones:

a + c = 12

a*2 ton + c*3 ton = 33 ton

Para resolverlo, primero aislamos una de las variables en una de las ecuaciones, aislemos a en la primera:

a = 12 - c

Ahora reemplazamos esto en la otra:

(12 - c)*2 ton + c*3 ton = 33 ton

24 ton + c*1 ton = 33 ton

c*1 ton = 9 ton.

c = 9

Es decir, hay 9 camionetas.

Entonces los 3 vehículos restantes son autos.

Hay 9 camionetas y 3 autos.

Based on the payoffs and the probabilities given, we can calculate the mean to be <u>0.8 shots made. </u>

The mean in this scenario will be a weighted average of the probabilities that a number of shots will be made.

The mean will be:

<em>= ∑ (Number of shots x Probability of number of shots)</em>

= (0 x 0.36) + (1 x 0.48) + (2 x 0.16)

= 0.8 shots

In conclusion, the mean is 0.8 shots.
