Question

A college admissions office uses the following linear equation to predict the grade point average of an incoming student: z = 0.003x + 0.8y − 4 where z is the predicted college GPA on a scale of 0 to 4.3, and x is the student's total SAT score on a scale of 400 to 1600, and y is the student's high school GPA on a scale of 0 to 4.3. The college admits students whose predicted GPA is at least 2.3. (a) Will a student with a total SAT score of 1050 and high school GPA of 3.2 be admitted? noyes (b) Will every student with a total SAT score of 1600 be admitted? noyes (c) Will every student with a high school GPA of 4.3 be admitted? noyes (d) Which is more important, an extra 100 points on the SAT or an extra 0.5 of high school GPA? 100 points on the SAT0.5 points of high school GPA
