The Gray isn't interests example that most students are required to take upon entering graduate school in 2014 the combined sources for a variable and quantitative section to approximately normally distributed with a mean of 310 and a standard deviation of 12 What percents of squares where between 286 and 322

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

my answer got deleted but it's a

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
