Question

the accompanying bar graph shows the resident population and the land area of a particular country for selected years from 1800 through 2019. use the information to find the population density of a certain country, to the nearest tenth, expressed in people per square kilometer, in 1900. click here to view the bar graph. the population density in 1900 was approximately (round to the nearest tenth as needed.)
1 in² = 6.5 cm²
1 ft² = 0.09 m²
1 yd² = 0.8 m²
1 mi² = 2.6 km²
1 acre = 0.4 hectare (ha)

Explanation:

To solve the problem of finding the population density in 1900, we need the population and the land area of the country in 1900 from the bar graph (which is not visible here). However, assuming we have the population \( P \) and land area \( A \) (in square kilometers) from the graph, the formula for population density \( D \) is:

\[
D = \frac{P}{A}
\]

Step 1: Obtain Population (\( P \)) and Land Area (\( A \)) from the Bar Graph

Let's assume from the bar graph:

• Population in 1900: \( P \) (e.g., if \( P = 10,000,000 \) people)
• Land Area in 1900: \( A \) (e.g., if \( A = 5,000,000 \) square kilometers)

Step 2: Calculate Population Density

Using the formula \( D = \frac{P}{A} \):
\[
D = \frac{10,000,000}{5,000,000} = 2.0
\]

(Note: The actual values will depend on the data from the bar graph. Replace \( P \) and \( A \) with the correct values from the graph and compute the density, then round to the nearest tenth.)

Since the bar graph data is not provided, we can't compute the exact value. But the general method is to divide the population by the land area (in square kilometers) to get the density (people per square kilometer) and round to the nearest tenth.

For example, if the population in 1900 is \( 12,345,678 \) and the land area is \( 6,789,012 \) km²:
\[
D = \frac{12,345,678}{6,789,012} \approx 1.8
\]

Final Answer

(The answer will depend on the actual data from the bar graph. Once you have the population and land area, compute \( \frac{\text{Population}}{\text{Land Area}} \) and round to the nearest tenth.)

If we assume sample data (e.g., Population = 15,000,000, Land Area = 7,500,000 km²):
\[
D = \frac{15,000,000}{7,500,000} = 2.0
\]
So the population density would be \(\boxed{2.0}\) (people per square kilometer) (this is a sample; use actual data from the graph).
