The following table shows the estimated populations and annual growth rates for four countries in the year 2000. Find the expect

Softa [21]

Answer:

For Australia: 22,044,350

For China: 1,545,744,200

For Mexico: 145,507,500

For Zaire: 92,237,875

Step-by-step explanation:

For Australia: Population in 2000 is 19,169,000 and it is increasing steadily at a rate of 0.6% per year.

Therefore, the population in the year 2025 will be

$19169000[1+\frac{0.6 \times 25}{100} ]= 22,044,350$ (Answer)

For China: Population in 2000 is 1,261,832,000 and it is increasing steadily at a rate of 0.9% per year.

Therefore, the population in the year 2025 will be

$1261832000[1+\frac{0.9 \times 25}{100} ]= 1,545,744,200$ (Answer)

For Mexico: Population in 2000 is 100,350,000 and it is increasing steadily at a rate of 1.8% per year.

Therefore, the population in the year 2025 will be

$100350000[1+\frac{1.8 \times 25}{100} ]= 145,507,500$ (Answer)

For Zaire: Population in 2000 is 51,965,000 and it is increasing steadily at a rate of 3.1% per year.

Therefore, the population in the year 2025 will be

$51965000[1+\frac{3.1 \times 25}{100} ]= 92,237,875$ (Answer)

A bag contains 40 marble 12 red and 16 yellow what is the probability that a blue is randomly seclected

lora16 [44]

Answer:

Fraction=3/10

Decimal=0.3

Percent=30%

Step-by-step explanation:

First we have to add 12+16 so we can find how many marbles are left

12+16=38

Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles

40-38=12

There are 12 blue marbles.

Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.

Probability=

12/40

Simplify

12/40

6/20

3/10

Probability

Fraction=3/10

Decimal=0.3

Percent=30%
