Use this example to answer the question. On an island in the South Pacific, there is a population of 1,000 South Pacific Splendor Birds. There is no immigration or emigration but there are 40 births and 20 deaths per year.

4. The annual percentage rate of this population is

A. 0.02%.
B. 2.0%.
C. 20%.
D. -0.02%.
E. -2%.

B; 2.0%

Step-by-step explanation:

In this question, we are asked to calculate the annual percentage of death in a population that has 20 deaths out of a total of 1000 birds.

To do this, we need to divide the number of deaths over the total number of deaths and multiply by 100%

Mathematically, this can be related as follows;

20/1000 * 100 = 2000/1000 = 2%

The percentage of death in the bird population is 2%

B. 2.0%.

Step-by-step explanation:

This question can be solved using a rule of three.

The population is of 1000(which is 100%).

There is no immigration or emigration but there are 40 births and 20 deaths per year.

40 - 20 = 20

How much it is?

1000 - 100%

20 - x%

1000x = 20*100

1000x = 2000

x = 2000/1000

x = 2

So the correct answer is:

B. 2.0%.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
