7th grade has 3 boy out of 10 students
probability of picking a boy is 3/10
8th grade has 9 boys out of 12 students are boys

Answer:
g(f(- 2)) = 91
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x), that is
f(- 2) = - 2 + 7 = 5 , then
g(5) = 4(5)² - 9 = 4(25) - 9 = 100 - 9 = 91
