there are 15 finalist in a singing competition. the top five singers receive prizes. how many ways can the singer finish first through fifth
Answers
Answer:
The singers can finish first through fifth in 360360 ways.
Step-by-step explanation:
The order of the singers is important, because they are ranked by positions. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
Top five singers, from 15 finalists. So
[tex]P_{(15,5)} = \frac{15!}{(15-5)!} = 360360[/tex]
The singers can finish first through fifth in 360360 ways.

Which of the following types of statement cannot be used to explain the
steps of a proof? Check all that apply.
A. Conjecture
B. Guess
OC. Postulate
0 D. Theorem
Answers
Answer:
A. Conjecture
B. Guess
Steps of a proof cannot be explained using A. conjecture and B. guess.
What is Conjecture?Conjectures in mathematics is a term which is given to the situation where something is guessed without any proof or basics.
This may be true, but are not proved up to this day.
Theorems are something which are already proved. This can be used in figuring out the proof of any problems.
Similarly, postulates are something which are the special cases of a certain proof. These can also be used to prove anything in mathemetics.
But guess and conjectures are not already proved statements. So these cannot be used.
Hence the options are Guess and Conjectures.

5 (2x+1) +4 (x+1)=12(x+2)
Answers
Answer:
x=–/-4
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2)(1)+4(x+1)=x+2
Step 1: Simplify both sides of the equation.
5(2)(1)+4(x+1)=x+2
5(2)(1)+(4)(x)+(4)(1)=x+2(Distribute)
10+4x+4=x+2
(4x)+(10+4)=x+2(Combine Like Terms)
4x+14=x+2
4x+14=x+2
Step 2: Subtract x from both sides.
4x+14−x=x+2−x
3x+14=2
Step 3: Subtract 14 from both sides.
3x+14−14=2−14
3x=−12
Step 4: Divide both sides by 3.

70%of it is 14 min find the valy ofx
Answers
Note:
Your questions sound a little unclear.
But, I am assuming your questions as:
''70% of x is 14 min. Find the value of x''.
So, I will solve assuming this statement which anyways would clear your concept.
Answer:
The value of x = 20.
Step-by-step explanation:
Given
''70% of x is 14 min. Find the value of x''.
Thus,
70% of x = 14
70/100 × x = 14
0.7x = 14
divide both sides by 0.7
0.7x/0.7 = 14/0.7
x = 20
Therefore, we conclude that the value of x = 20.

4m + 12
Therefore, 4(m + 3) = 4m + 12
✔️6m - 2m + 12
4m + 12
Therefore, 6m - 2m + 12 = 4m + 12
✔️3m - m + 12
2m + 12
Therefore, 3m - m + 12 ≠ 4m + 12
✔️4(m + 12)
4*m + 4*12
4m + 48
Therefore, 4(m + 12) ≠ 4m + 12
