Alicia has 6 paintings she wants to hang side by side on her wall. a) in how many ways can she arrange all 6 paintings? show your work. b) if she only wants to display 4 of the paintings, in how many ways can she choose the paintings she wishes to display? show your work. c) in how many ways can she arrange 3 out of the 6 paintings? show your work.

A) 720 ways

B) 15 ways

C) 6 ways

Step-by-step explanation:

A) To find the number of ways Alicia can arranger her 6 paintings, we will find factorial of 6 by multiplying all of the positive integers equal to or less than that number i.e. 6 to get:

6! = 6 * 5 * 4 * 3 * 2 * 1 = 720

Alicia can arrange her paintings in 720 ways.

B) We use the following formula (when order is not important) to find the number of permutations of n objects taken r at a time:

Therefore, Alicia can choose any 4 of her paintings in 15 ways.

C) Number of ways Alicia can arrange 3 out of 6 paintings = 3! = 3*2*1 = 6 ways

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

126 maybe. sorry
