The initial population size can be found by substituting values for "T"
At time zero, there are no birds because
·(2×0)×100=0
At time 1 there would be 200 birds this is because
·(2×1)×100=200
And the start besides time Zero would be at time 1, there for the initial population would be represented by the population at time 1, which is 200.
In conclusion the initial population in this equation would be 200.

Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.
Step-by-step explanation:
Answer:
(-2, -2)
Step-by-step explanation:
They are proportional. If you divide 6/36 by 6 on the numerator and the denominator, you get the same fraction of 1.6.
Answer:
D is a binomial random variable with 
Step-by-step explanation:
For each customer, there are only two possible outcomes. Either they have dogs, or they do not. The probability of a customer having a dog is independent of any other customer. This means that D is a binomial random variable.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
65% of the customers have dogs:
This means that 
15 customers:
This means that
