The total change in the amount of water in the pool is 288 gallons.
<h3>What is Volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
Here, Rate of water pumped into her pool = 6 gallons / minute.
Total Duration = 48 minutes
Total amount of water = Rate X Time
= 6 X 48
= 288 gallons
Thus, the total change in the amount of water in the pool is 288 gallons.

She runs about 4.2 miles.
Step-by-step explanation:
6/50 = x/35
6*35 = 50*x
210 = 50x
50x = 210
x = 210/50

Answer:
H0: p1=p2 against the claim Ha: p1≠p2
Step-by-step explanation:
Here the proportion of the people going for medical checkup before the program is p1= 0.76
The proportion of the people going for medical checkup after the program is p2= 686/880=0.78
Our null and alternate hypothesis will be
H0: proportion of the people going for medical checkup before the program <u>is equal </u>to the proportion of the people going for medical checkup after the program
against the claim
Ha: proportion of the people going for medical checkup before the program <u>is not equal </u>to the proportion of the people going for medical checkup after the program
Mathematically this can be written as
H0: p1=p2 against the claim Ha: p1≠p2
