An experiment involves 17 participants. From these, a group of 3 participants is to be tested under a special condition. How many groups of 3 participants can be chosen, assuming that the order in which the participants are chosen is irrelevant?

680

Step-by-step explanation:

When order doesn't matter,then the number of combinations of choosing r things out of n =

Given: Total participants = 17

From these, a group of 3 participants is to be tested under a special condition.

Number of groups of 3 participants chosen =

Hence, there are 680 groups of 3 participants can  be chosen,.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
