Tossing a coin for many different times does not change the probability of getting a head (or tail) for the next toss. This indicates that the events are independent events.
So, given that the coin is fair, the probability of showing a head on the next toss is 1/2 or 0.5.
This probability does not change for all toss.
Answer:
3.5
Step-by-step explanation:
The answer is 14. y = 14 hope it helps.
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons
b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours
It ca be simplified to 48
