Answer:

<em />

  • <em>It takes</em><u>     2.5 minutes   </u><em>to fill the tank.</em>

Explanation:

The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:

  • Net rate = rate of filling - rate of leaking
  • Net rate = 5 liters/minute - 1 liter/minute
  • Net rate = 4 liters/minute

Thus, consiedering the tank is empty at the beginning, the time is:

  • Time = Volume of the tank / net rate of filling
  • Time = 10 liters / (4liters/minute)
  • Time = 2.5 minutes ← answer

Voltage sags and swells. Refer to the Electrical Engineering (Vol. 95, 2013) study of transformer voltage sags and swells, Exerc
Artist 52 [7]

Answer:

a. z-score for the number of sags for this transformer is  ≈ 1.57 . The number of sags found in this transformer is within the highest 6% of the number of sags found in the transformers.  

b. z-score for the number of swells for this transformer is ≈ -3.36. The number of swells found in the transformer is extremely low and within the lowest 1%

Step-by-step explanation:

z score of sags and swells of a randomly selected transformer can be calculated using the equation

z=\frac{X-M}{s} where

  • X is the number of sags/swells found
  • M is the mean number of sags/swells
  • s is the standard deviation

z-score for the number of sags for this transformer is:

z=\frac{400-353}{30} ≈ 1.57

the number of sags found in the transformer is within the highest 6% of the number of sags found in the transformers.  

z-score for the number of swells for this transformer is:

z=\frac{100-184}{25} ≈ -3.36

the number of swells found in the transformer is extremely low and within the lowest 1%
