To predict the population in the year 2030 using the linear model \( y = 0.83x + 30 \), we need to substitute \( x = 30 \) into the equation.
So,
\[ y = 0.83(30) + 30 \]
Calculating this step by step:
- Calculate \( 0.83 \times 30 \):
\[ 0.83 \times 30 = 24.9 \]
- Now, add 30:
\[ y = 24.9 + 30 = 54.9 \]
Thus, the predicted population in the year 2030 is:
\[ y = 54.9 \text{ million} \]
Therefore, the correct response is:
In 2030, the population of the state will be 54.9 million people.
