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 30.03 million people.
In 2030, the population of the state will be 30.03 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 0.83 million people.
In 2030, the population of the state will be 0.83 million people.

Answer 1

To predict the population of the state in 2030 using the given linear model \(y = 0.83x + 30\), we set \(x = 30\) because 2030 is 30 years after 2000.

Substituting \(x = 30\) into the equation:

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

Calculating \(0.83 \times 30\):

\[
0.83 \times 30 = 24.9
\]

Now, add this to 30:

\[
y = 24.9 + 30 = 54.9
\]

Thus, the predicted population in 2030 is:

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