Ответ:
D. 5040
Step-by-step explanation:
Given : The total number of books = 10
The number of books required by Clarissa = 4
Now , when we select r things from n things and order in which they are chosen matters then we use permutations to calculate the number of different lists are formed to choose them.
The number of permutations of n things taking r at a time is given by :-
For r= 4 and n= 10 , we have
Hence, the number of different lists are possible = 5040
Therefore , the correct answer = D. 5040
Ответ:
x=28
Step-by-step explanation:
I am assuming the mean is arithmetic mean. So we first add up the numbers:
6+10+12+18+16+x
=22+10+30+x
=22+40+x
=62+x
Then since there's 6 numbers in total, we have an equation:
The answer is 28!
Have a nice day! :)
