Question

the graph shows the world population since 1950. world population 1950–2010 population billions 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 time period (years) 1950 1965 1980 1995 2010 2025 what is the projected population size in 2025? ○ 6 billion ○ 7.5 billion ○ 8.5 billion ○ 9 billion

Explanation:

To determine the projected population in 2025, we analyze the graph. The x - axis represents the time period (years) and the y - axis represents the population (in billions). Looking at the data points and the trend of the line graph, at the year 2025 on the x - axis, the corresponding population value on the y - axis is 8.5 billion. We can eliminate the other options: 6 billion is too low (the population was already above 6 billion before 2025), 7.5 billion is also lower than the trend suggests at 2025, and 9 billion is higher than the value shown by the graph at 2025.

Answer:

8.5 billion
