Statement 1: The line joining the points (8,-8) and ((1)/(2),2), which are on the parabola y^(2)=8x, press through the focus of the parabola.Statement 2: Tangents drawn at (8,-8) and ((1)/(2),2), on the parabola y^(2)=4ax are perpendicular.

The standard deviation for the set of numbers, 1,4,5,7,8 is nearly 2.45. If 10 are added to each number, then the new standard deviation will be

2/3 of 8 is same as 2/3 // 8

which one is greater 8^(2) or 2^(8)?
