Answer:
There are 2,520 unique permutations.
Step-by-step explanation:
When we have a set of N different elements, the total number of permutations is given by:
P = N! = N*(N - 1)*(N - 2)*...*(2)*(1)
Particularly, if out of these N elements, there are a given element that is repeated K times, then the permutations of these K elements actually do not add new unique permutations, then in that case the total number of unique permutations is:
P = N!/K!
And if we have another element that is repeated L times, then with the same reasoning than above, the total number of unique permutations is:
P = N!/(K!*L!)
Now, we have the set:
{C, E, A, S, E, L, E, S, S}
So we have a set of 9 letters, then:
N = 9
And, the letter S is repeated 3 times
The letter E is repeated 3 times
Then, using the above notation, we can define:
K = 3
L = 3
The total number of permutations is then:
So there are 2,520 unique permutations.
Answer:
2 units
Step-by-step explanation:
We are given that
Angle ,radian
Length of an arc=
We have to find the radius of circle in simples form.
We know that
Where l=Length of arc
r=Radius of circle
Using the formula
units
Hence, the radius of the circle=2 units
The mean is the average value of the numbers given in the series
The mode is the number that is appears more than any other number given in the series
Step-by-step explanation:
Given challenge is make a list of 5 numbers
The list of 5 number is = 8,10,12,15,15
so required mean is 12 has been computed
Mode = 15 ( the number 12 is appeared in two times 8,10,12,15,15)
Final answer
The required numbers are = 8,10,12,15,15
