Da shari wants to rearrange the four sweaters, two coats, and five jackets that are in her closet. if she puts a sweater first and a jacket last, how many different ways can she arrange them?

9! = 3,62,880 ways                  

Step-by-step explanation:

Number of sweaters= 4

No. of coats = 2

No. of jackets = 5

Total = 11

If she puts a sweater first and a jacket last, these two things have fixed places.

Now, number of sweaters = 4 (Since 1 sweater is placed in the first place)

No. of coats = 2

No. of jackets = 4 (Since 1 jacket is placed in the last place)

Total = 9

So, no. of ways in which these 9 things can be arranged = 9!

                                                                                              = 3,62,880 ways

Hence, these things can be arranged in 3,62,880 ways.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
