------------------------------------------------ The admissions office of a college wants to determine whether there is a relationship between IQ scores and grade-point averages $y$ after the first year of school. An equation that models the data obtained by the admissions office is:

\[ y = 0.063x - 4.759 \]

Estimate the values of $x$ that predict a grade-point average of at least 3.0. Simplify your answer completely. Round your answer to the nearest whole number.

In this question, we are given an equation that models the relationship between IQ scores (x) and the grade-point averages (y) after the first year of school. The equation is y = 0.063x - 4.759. We need to estimate the values of x that predict a grade-point average of at least 3.0.

To do this, we can set up the equation y = 3.0 and solve for x.

3.0 = 0.063x - 4.759

7.759 = 0.063x

x = 123

Therefore, we estimate that an IQ score of at least 123 is needed to predict a grade-point average of at least 3.0.

In conclusion, we estimate that an IQ score of at least 123 is needed to predict a grade-point average of at least 3.0.
