The accompanying bar graph shows the resident population and the land area of a particular country for selected years from 1800 through 2000. Use the information to complete parts (a) and (b) below. a. Find the population density of the country to the nearest terth in 1900 and in 2000 b. Find the percent increase in population density to the nearest tenth of a percent, from 1900 to 2000 (1) Click here to view a bar graph showing resident population and the land area of a particular country for selected years from 1800 through 2000 a. The population density to the nearest tenth in 1900 was square square (Round to the nearest tenth as needed) The population density, to the nearest tenth, in 2000 was square square (Round to the neares tenth as needed) b. The percent increase in population density from 1900 to 2000 was square % (Round to the nearest tenth as needed)

To find the population density, we need to divide the population by the land area. <br /><br />a. In 1900, the population was 75 million and the land area was 8 million square kilometers. So, the population density in 1900 was 75 million / 8 million = 9.375 people per square kilometer. Rounding to the nearest tenth, we get 9.4 people per square kilometer.<br /><br />In 2000, the population was 1.3 billion and the land area was 9.6 million square kilometers. So, the population density in 2000 was 1.3 billion / 9.6 million = 135.4167 people per square kilometer. Rounding to the nearest tenth, we get 135.4 people per square kilometer.<br /><br />b. To find the percent increase in population density from 1900 to 2000, we first need to find the difference in population density between the two years. The difference is 135.4 - 9.4 = 126 people per square kilometer. Then, we divide this difference by the population density in 1900 and multiply by 100 to get the percentage increase. So, the percent increase in population density from 1900 to 2000 was (126 / 9.4) * 100 = 1341.49%. Rounding to the nearest tenth, we get 1341.5%.<br /><br />So, the answers are:<br />a. The population density to the nearest tenth in 1900 was 9.4 people per square kilometer. The population density, to the nearest tenth, in 2000 was 135.4 people per square kilometer.<br />b. The percent increase in population density from 1900 to 2000 was 1341.5%.
