The population growth of a state since 2000 in millions of people is represented by a linear model. Using the trend line, y=0.83x+30 , predict the population, y , in the year 2030. Let x=30 because the year 2030 is 30 years after the year 2000.(1 point)

Question

Responses

In 2030, the population of the state will be 60.83 million people.
In 2030, the population of the state will be 60.83 million people.

In 2030, the population of the state will be 0.83 million people.
In 2030, the population of the state will be 0.83 million people.

In 2030, the population of the state will be 54.9 million people.
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.

Answer 1

To predict the population for the year 2030 using the provided linear model \( y = 0.83x + 30 \), we substitute \( x = 30 \):

\[ y = 0.83(30) + 30 \]

Calculating \( 0.83 \times 30 \):

\[ 0.83 \times 30 = 24.9 \]

Now, add 30:

\[ y = 24.9 + 30 = 54.9 \]

Thus, the predicted population in 2030 is:

\[ \text{In 2030, the population of the state will be } 54.9 \text{ million people.} \]

So the correct response is:

In 2030, the population of the state will be 54.9 million people.
