How many different ways can 12 people line up to go to the same bathroom
Aneli [31]
There are 12! ways to line 12 people up.  That is 12 factorial (the name for the exclamation point
12! means 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Using a scientific calculator to compute 12!, we get 479,001,600 ways to line up 12 people.  I know it sounds amazing but here is a chart.

People            Ways

3                       6
4                      24  (Notice that if you multiply 6 x 4 you get 24)
5                     120  (Notice that if you muliply 24 x 5 you get 120  etc.)
6                     720
7                     5040
8                    40,320
9                    362,880
10                 3,628,880
11               39,916,800

HELP PLEASE I NEED THIS DONE ASAP
Nata [24]

a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to  45/99  which is  <em>5/11</em> .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is  4/10

The 0.5555555555.../10 part is  5/90 .

(4/10) + (5/90) = <em>41/90 </em>

c). 0.45 means 45/100 .  That's <em> 9/20</em> .

I don't think you're supposed to be posting unit test questions on Brainly.
