To find the probability that both balls are white you will find the probability of getting a while ball from each situation separately and then multiply these probabilities together.
1. 7/14 or 1/2 chance
2. 3/9 or 1/3 change
1/2 x 1/3 = 1/6
You will have a 1 in 6 chance of getting a white ball from both urns.
Answer:
6y-12
Step-by-step explanation:
Answer:
10,995.6 ft^3.
2300.3 gallons.
(both to the nearest tenth).
Step-by-step explanation:
Area of the surface of the river = area of the outer circle - area of the inner circle.
Radius of the outer circle = 30 *3 = 90 feet.
So the surface area of the river = π(90)^2 - π(85)^2
= 875π ft^2
Also the volume of the river = surface area * depth = 875π*4 = 3500π ft^3
= 10,995.6 ft^3.
Number of gallons of water it will hold = 10,995.6 / 4.78
= 2300.3 gallons.
Answer:
y+30
Step-by-step explanation:
the sum of the numbers is 15y
the new sum after increase each number by 30 is 15y+450
the new mean 15y+450/15
= y+30
