To predict the population in the year 2030 using the provided linear model \( y = 0.83x + 30 \), we need to substitute \( x = 30 \) (since 2030 is 30 years after 2000):
\[ y = 0.83(30) + 30 \]
Now perform the multiplication:
\[ y = 24.9 + 30 \]
Now, add the two values:
\[ y = 54.9 \]
Therefore, the predicted population in the year 2030 will be 54.9 million people.
So, the correct response from the provided options is: In 2030, the population of the state will be 54.9 million people.
