Answer to Question #1081 in Algebra for Sammy
Please provide the steps to find the answer for each question 1,2, and 3! Thank u :)&
1) To the nearest tenth, what is average GPA of a student who doesn't study?&
2) To the nearest tenth, what is the average GPA of a student who studies 12 hours per week?&
3) To the nearest tenth, how many hours of studying are required for the average student to achieve a 3.2 GPA?
G(h=0) = 1.2
2. G(h=12) = 0.006*122+0.02*12+1.2 = 2.2
3. G(h) = 3.2
0.006h2+0.02h+1.2 = 3.2;
0.006h2+0.02h - 2 = 0;
D = 0.0004 + 0.048 = 0.0484
h = (-0.02 + 0.22)/0.012 = 16.7 hours
