The population growth of a state since 2000 in millions of people is represented by a linear model. Using the
trend line, y = 0.83 + 30, predict the population, y, in the year 2030. Let ∞ = 30 because the year 2030 is
30 years after the year 2000. (1 point)
O In 2030, the population of the state will be 0.83 million people.
O In 2030, the population of the state will be 60.83 million people.
O In 2030, the population of the state will be 54.9 million people.
• In 2030, the population of the state will be 30.03 million people.
To predict the population, we substitute the value of ∞=30 into the linear model y = 0.83 + 30:
y = 0.83 + 30 = 30.83
Therefore, in 2030, the population of the state will be approximately 30.83 million people.
The correct answer is:
In 2030, the population of the state will be 30.83 million people.
