Answer:
60
Step-by-step explanation:
1/2 of 80 is 40.1/4 is 20.40 plus 20 equals 60.
#18 is false because 1.9 is equal to 1.90
Given that the volume of water remaining in the tank after t minutes is given by the function
where V is in gallons, 0 ≤ t ≤ 20 is in minutes, and t = 0 represents the instant the tank starts draining.
The rate at which water is draining four and a half minutes after it begins is given by
Therefore, the water is draining at a rate of 1,550 gallons per minute four ans a half minutes after it begins.
1/36
the first one has a probability of 1/6
the second one or 1/6
if you multiply them together you get 1/36
They were multiplied together since the two events depend on each other. If one does nit get a 4, then both of them will obviously not have a 4
