how many arrangements of 1,2,...,n are there in which only tthe odd integers must be deranged (even integers may be in their own poositions)?

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag

c 5 gallons mark me as brainlest
