Step-by-step explanation:
Initial population of people living in the island is 20,000
P = 20,000
It was compounded annually. This means that it was compounded once in a year. So
n = 1
The rate at which the population was compounded is 5%. So
r = 5/100 = 0.05
It was compounded for 5 years. So
t = 1
the exponential growth function is expressed as
A = P(1+r/n)^nt
A = total population in the island at the end of t years. Therefore
A = 20000 (1+0.05/1)^1×5
A = 20000×1.2762815625
A = 25525.63125
The number of inhabitants that the island will have after 5 years is approximately 25526 people

Step-by-step explanation:
The answer is 7/69.
There are 8 black-haired children among 24 children. The probability of <span>randomly selecting black haired children for the first time is:
P1 = 8/24 = 1/3
Now, there are 7 black-haired children left among 23 children. The probability of </span>randomly selecting black haired children for the second time is:
P2 = 7/23
Since we want both of these events to occur together, we will multiply their probabilities:
P = P1 * P2 = 1/3 * 7/23 = 7/69
It's so easy just keep on reading it
