Since its out of 15 marbles all together and all you need to find is the probability of 3 blue marbles you would have to divide 3 by 15. The outcome would be 0.2 or in your case... B. - 0.20
Answer:
<em>The initial population size is 500 fish</em>
<em>Population size after 9 years: 1910 fish</em>
Step-by-step explanation:
<u>Mathematical Model</u>
We usually represent real situations as mathematical functions or rules that express the dependency of one variable quantity P with another variable quantity t.
The population size of a species of fish P(x) is modeled by the following function:

Where t is the number of years elapsed since the species was added to the lake.
The initial population size can be found by substituting t for 0:



P(0)=500
The initial population size is 500 fish
The population size after t=9 years is:




Population size after 9 years: 1910 fish
V = (π/4)d^2*h
Using the given numbers,
V = (3.14/4)*(24 m)^2*(10 m)
V = 4521.6 m^3
The volume is 4521.6 kL.
Should be 262.5.105 times 2=210 for one hour.105 divided by 2 to have 1\4=52.5.210+52.5 equals 262.5
