Answer:

  • Tower #1: 1550 gallons
  • Tower #2: 670 gallons

Step-by-step explanation:

After 5 minutes, the amount of water that has flowed is ...

  (20 gal/min)(5 min) = 100 gal

That amount has flowed out of Tower #1, so it now has ...

  1650 -100 = 1550 . . . gallons in Tower #1

That amount has flowed into Tower #2, so it now has ...

  570 +100 = 670 . . . gallons in Tower #2

Which of the following statements is not​ true? A. If the probability of an event occurring is​ 1.5, then it is certain that event will occur. B. If the probability of an event occurring is​ 0, then it is impossible for that event to occur.

Answers

Answer:

Therefore, we conclude that the statement in (A) is incorrect.

Step-by-step explanation:

We have the following sentences:

A) If the probability of an event occurring is​ 1.5, then it is certain that event will occur.  

B) If the probability of an event occurring is​ 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that  is equal to 1.5.

Therefore, we conclude that the statement in (A) is incorrect.
