Answer:
14
Explanation:
For independent variables X and Y;
S.D(X - Y) is expanded as :
S.D(X) + S.D(Y)
If S.D(X) = 6 and S.D(Y) = 8 ; where, X and Y are independent ;
SD(X-Y) = SD(X) + SD(Y)
SD(X - Y) = 6 + 8
SD(X - Y) = 14
We suggest starting to prep for the the SAT as early as eighth grade year. It sound early, but if a student plans on taking the SAT several times throughout high school, eighth graders can take a relaxed and long-view approach to prepping, and can plan on taking their first SAT sophomore year.
