The rate at which the windows are washed can be described by the number of windows cleaned each minute. Thus, the missing value represents how many windows she has managed to wash.

Answer: La probabilidad que necesitamos es 0.16.

Step-by-step explanation:

Se nos proporciona que

La probabilidad de que el estudiante sea un senior = 0.22

La probabilidad de que el estudiante tenga una licencia de conducir = 0.30

La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36

Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.

Según la pregunta,

P(S\cap D)=P(S)+P(D)-P(S\cup D)\\\\P(S\cap D)=0.22+0.30-0.36\\\\P(S\cap D)=0.16

Por lo tanto, la probabilidad que necesitamos es 0.16.

En una fábrica de automóviles que trabaja las 24 horas se arman diariamente 24
Svet_ta [4341]

Answer:

a. La ganancia total es de $ 4,060,000.00

b. 31 vehículos fabricados

Step-by-step explanation:

(a) Los datos suministrados son;

Cantidad de autos tipo sedán producidos = 24

Cantidad de SUV ensamblados = 16

Cantidad de vehículos tipo VAN producidos = 12

Cantidad de pick-ups fabricadas = 8

Cantidad de autos deportivos producidos = 2

Ganancia de los autos sedán vendidos = $ 185,000 - $ 140,000 = $ 40,000

Ganancia por las SUV vendidas = $ 320,000 - $ 250,000 = $ 70,000

Ganancia de los vehículos tipo VAN = $ 400,000 - $ 310,000 = $ 90,000

Ganancia de las pick-ups = $ 285,000 - $ 210,000 = $ 75,000

Ganancia de los autos deportivos vendidos = $ 550,000 - $ 400,000 = $ 150,000

La ganancia total se calcula de la siguiente manera: 24 * $ 40,000 + 16 * $ 70,000 + 12 * $ 90,000 + 8 * $ 75,000 + 2 * $ 150,000 = $ 4,060,000

(b) Debido a que hay una producción constante, solo se completará la mitad del total de automóviles en un lapso de 12 horas

Por lo tanto, se fabrican

12 sedanes, 8 SUV, 6 VAN, 4 pick-ups y 1 deportivo, alcanzando así un total de 31 vehículos.
