Answer: 6720
Step-by-step explanation:
The number of permutations of n things taken r at a time is given by the following formula:
Similarly, for n=8 and r=5, the number of permutations of 8 things taken 5 at a time will be:
Hence,
The permutation is solved and the expression is ⁸P₅ = 6,720
Given data ,
The notation "8P5" represents the permutation of 8 objects taken 5 at a time.
The formula for permutation is given by: P(n, r) = n! / (n - r)!
Using this formula, we can calculate ⁸P₅ as follows:
permutation ⁸P₅ = 8! / (8 - 5)!
⁸P₅ = 8! / 3!
⁸P₅ = (8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1)
⁸P₅ = 8 * 7 * 6 * 5 * 4
permutation ⁸P₅ = 6,720
Therefore, the expression ⁸P₅ is equal to 6,720
Hence , the permutation is solved

Answer:
Step-by-step explanation:
divide 4.5/4.8. you get .9375.
subtract this from 1
1-.9375
and you get 0.0625.
multiply that by 100 to get it into percent form
6.25%
The sum of 15 and it's additive inverse is 0.
What is additive inverse?
If the sum of two number is 0. Then the numbers are called additive inverse of each other.

The opposite of a number. For example, the additive inverse of 12 is –12. The additive inverse of –3 is 3. Formally, the additive inverse of x is –x. Note: The sum of a number and its additive inverse is 0. Hope i helped :)
