Hannah wants to see if her new technique of ping-pong playing can decrease the time it takes to finish a ping-pong game. She asks the U. S. Olympic ping-pong team to work with her. Half of the U. S Olympic team is randomly assigned to be taught by the new style, the experimental group, and the other randomly assigned half are not, the control group. Her technique does not significantly decrease the time it takes the experimental group to finish a ping-pong game compared to the control group, perhaps because they are already so good at the sport. This could be an example of:

-8

step-by-step explanation:

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

its a i did it myself
