PLZ HELP ON A TEST NEEDED ASAP Research shows the United States uses 45,000 water bottles every 30 seconds. At this rate, how many water bottles are used in the United States in 45 seconds?

67500 bottles

Step-by-step explanation:

The rate of use of water bottles is 45000bottles/30sec

the unit rate of use of water bottles is 1500bottles/1sec

multiply by 45 to get the number of bottles used in 45 seconds

1500/1sec *45sec=67500 bottles

C: 0.25  have a good day mark me brainliest now and give me thanks

Step-by-step explanation:

We will use conditional probability formula to solve our given problem.

, where,

= Probability of event B, given probability of event A.

= Probability of event A and event B.

= Probability of event A.

Let us substitute our given values in conditional probability formula.

= Probability that a student plays a sport given that student is a senior.

=The probability that a student is a senior and plays a sport = 0.05.

= Probability that a student is a senior = 0.20.

Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior will be 0.25 and option C is the correct choice.
