Answer: No solution
Step-by-step explanation:
Let one number be x
Other no. will be 2x
x - 1/2(2x) = 20
x - x = 20
No solution
Answer:$9.3 is the bars and the rest is the apples
Step-by-step explanation:because you take away from the bars than what is left is the apples.
There are total 600 number of ways or permutations the top two finishers can be determined.
According to the given question.
Total number of people who are participating in a race = 25
In 25 participants the total number of participants to be selected to finish the race = 2
As we know that "a permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters". Which can be calculated as
![^{n}P_{r} = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5E%7Bn%7DP_%7Br%7D%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Where,
is the number of permutations
n is the total number of objects
r is the numbers of objects to be selected
Thereofore,
The total number of ways, or permutaions the two top finishers can be determined is given by
![^{25} P_{2}](https://tex.z-dn.net/?f=%5E%7B25%7D%20P_%7B2%7D)
= 25!/(25-2)!
= 25!/23!
= 25 × 24 × 23!/23!
= 25 × 24
= 600
Hence, there are total 600 ways or number of permutations the top two finishers can be determined.
