To find the mean number for the six-day period, begin by figuring the total number of tickets
sold:52 × 7 = 364
Since 46 tickets were sold on the last day, 318 tickets were sold before that day:364 − 46 = 318
To find the mean for the six-day period, divide this total by six:33 . C
To solve this problem, you need the formulas for the volumes and surface areas of spheres.Surface area = 4πr^2
Since the surface area of sphere A is 729 times greater than that of sphere B, the radius is
or 27 times greater.The volume of sphere A, therefore, is 27^3 or 19,683 times greater than the volume of sphere
B. So the ratio of the volumes is 19,683:1.34 . D
To find the inverse function f−1(x) of write the inverse function as an
equation and solve for y.
