QuestionTwo countries have populations of about 11.3 million and 689,000 , respectively. Their areas are 8744 and 619,771 square miles, respectively. Compute the population densities of the two countries
The population density of the first country is □\square people per square mile. (Type an integer or decimal rounded to the nearest tenth as needed.)

Studdy Solution

STEP 1

1. Population density is defined as the number of people per unit area (square mile in this case).
2. The first country has a population of 11.3 11.3 million and an area of 8744 8744 square miles.
3. The second country has a population of 689,000 689,000 and an area of 619,771 619,771 square miles.
4. We need to compute the population density for each country separately.

STEP 2

1. Convert populations to the same units.
2. Calculate the population density for the first country.
3. Calculate the population density for the second country.

STEP 3

Convert the population of the first country from millions to individuals.
11.3 million=11,300,000 people 11.3 \text{ million} = 11,300,000 \text{ people}

STEP 4

Calculate the population density for the first country using the formula:
Population Density=PopulationArea\text{Population Density} = \frac{\text{Population}}{\text{Area}}
For the first country:
Population Density=11,300,0008744\text{Population Density} = \frac{11,300,000}{8744}

STEP 5

Perform the division to find the population density for the first country:
Population Density≈1292.5 people per square mile\text{Population Density} \approx 1292.5 \text{ people per square mile}

STEP 6

Calculate the population density for the second country using the formula:
Population Density=PopulationArea\text{Population Density} = \frac{\text{Population}}{\text{Area}}
For the second country:
Population Density=689,000619,771\text{Population Density} = \frac{689,000}{619,771}

STEP 7

Perform the division to find the population density for the second country:
Population Density≈1.1 people per square mile\text{Population Density} \approx 1.1 \text{ people per square mile}
The population density of the first country is approximately:
1292.5 people per square mile\boxed{1292.5 \text{ people per square mile}}
The population density of the second country is approximately:
1.1 people per square mile\boxed{1.1 \text{ people per square mile}}
