Vladimir [108]

A) La probabilidad de que la cantidad total de la solución contenida en 50 tambores sea mayor a 1 500 L es del 50%.

B) La probabilidad de que puedan llenarse 80 tambores sin que se acabe la solución es del 75%.

C) La tina debe contener 2160 litros para que la probabilidad sea 0,9 de que puedan llenarse 80 tambores sin que se acabe la solución.

<h3><u>Desviación estándar</u></h3>

Dado que unos tambores, con una etiqueta de 30 L, son llenados con una solución proveniente de una tina grande, y se agrega una cantidad aleatoriamente de la solución en cada tambor con media de 30.01 L y desviación estándar de 0.1 L, para determinar A) ¿Cuál es la probabilidad de que la cantidad total de la solución contenida en 50 tambores sea mayor a 1 500 L?; B) Si la cantidad total de la solución en la tina es de 2 401 L, ¿cuál es la probabilidad de que puedan llenarse 80 tambores sin que se acabe la solución?; y C) ¿Cuánta solución debe contener la tina para que la probabilidad sea 0,9 de que puedan llenarse 80 tambores sin que se acabe la solución?, se deben realizar los siguientes cálculos:

A)

  • 30.01 - 0.1 = 2.91
  • 30.01 + 0.1 = 3.11
  • 3.11 - 2.91 = 20
  • 3.11 - 3.01 = 10
  • 10 / 20 = 0.5
  • 0.50 = X

B)

  • 2401 / 30.01 = X
  • 79.76 = X
  • 2401 / 30 = X
  • 80 = X
  • (100 + 50) / 2 = 75

C)

  • (80 x 30) x 0.9 = X
  • 2400 x 0.9 = X
  • 2160 = X

I think it is 45.00 because you multiply -4.50 x 5= -22.5. The reason you multiply x4.59 times 5 is because he takes away 4.50 every day for 5 days. And then you do 67.50-22.5=45.00.

Liono4ka [1.6K]

Answer:

a) 2nd

b) 4.8

c) 4

Step-by-step explanation:

Mode is the highest frequency.

"Away" has highest frequency in the second quarter

Mean = sum/n

Sum of Home goals:

5+4+8+9 = 26

Sum of Away goals:

2+9+7+4 = 22

Total goals = 26+22 = 48

Average = 48/10 = 4.8

No. of home goals - No. of away goals

26 - 22 = 4
