If the same bottle cap is flipped twice, what is the probability that two of them will be bottom side up? 150y^2 surface area of a cube. which is greater, volume of the same cube or 125y^3 Line making angle 48 degree with the x axis (slope negative, line trending downwards when moving from left to right) in the first quadrant, which is greater, sum of the coordinates of a point on the line or 0. Standard deviation of a set of numbers is 16. if 10 more 16s are added will the SD change?
