How many ways can you pick a President, Vice President, Secretary and Treasurer from a group of 12 people?

479,001,600

19,958,400

20,736

11, 880

20,736

Step-by-step explanation:

There are 12 people total in the room, so the base of the exponent will be 12.

Sine there are 4 possible positions, the exponent will be 4.

# of possibilities = 12^4

12^4 = 12 * 12 * 12 *12 = 20,736

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
