This spinner has 3 possible outcomes - white, grey or black.
janet says that 1 of the 3 outcomes is black so the probability hat the arrow will stop on black is 1/3.
is janet correct, why?

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Consider the integral: 4 0 16 − y2 − 16 − y2 4 1 x2 + y2 dz dx dy . (a) describe w. use the standard view of the x, y, and z axes. front half of a cone with a rounded top. full cone with a flat top. right half of a cone with a flat top. front half of a cone with a flat top. right half of a cone with a rounded top.
