20% in fraction form is....
1) 20 is the percent
2)to put it in a fraction form.......
3) you need to divide it by 100.
4) 20 /100 equals 0.2
5) 0.2 says it's out of 2/10
6) if you want to simplify you can so go ahead: 2/10 >>> (turns into) 1/5
7) 1/5 is your answer...
8) PLEASE GIVE THIS A THANKS AND THE BRAINIEST ANSWER/CROWN...IF NOT...WELL PLEASE DO :) :) :) :) :D :D :D ;D:D
![(x-5)(x^2-x-4) =x^3-6x^2+x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%20%3Dx%5E3-6x%5E2%2Bx%2B20)
Step-by-step explanation:
Given polynomials are:
![x^2-x-4\\and\\x-5](https://tex.z-dn.net/?f=x%5E2-x-4%5C%5Cand%5C%5Cx-5)
Both polynomials have to be multiplied. We will use distributive property for the said purpose
So,
![(x-5)(x^2-x-4)\\=x(x^2-x-4)-5(x^2-x-4)\\=x^3-x^2-4x-5x^2+5x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%5C%5C%3Dx%28x%5E2-x-4%29-5%28x%5E2-x-4%29%5C%5C%3Dx%5E3-x%5E2-4x-5x%5E2%2B5x%2B20)
Combining alike terms
![=x^3-x^2-5x^2-4x+5x+20\\=x^3-6x^2+x+20](https://tex.z-dn.net/?f=%3Dx%5E3-x%5E2-5x%5E2-4x%2B5x%2B20%5C%5C%3Dx%5E3-6x%5E2%2Bx%2B20)
Hence,
![(x-5)(x^2-x-4) =x^3-6x^2+x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%20%3Dx%5E3-6x%5E2%2Bx%2B20)

Answer:
4/5
Step-by-step explanation:
1, 2 , 3 and 4 are factors of 12
so 4 out of 5
4/5 is the probability of getting factor of 12
Part 1:
You have the correct answer. You multiply the probability of getting red (6/15) by the probailitiy of getting red (6/15) to get 36/225 which reduces to 4/25
--------------------------------
Part 2:
This is also correct. Nice work. You multiply the probability of getting black (9/15) with the probability of getting red (6/15) to get 54/225 = 6/25
--------------------------------
Part 3:
The probability of picking a black checker is 9/15. If a replacement is made, then the probability of picking another black checker is also 9/15. So,
(9/15)*(9/15) = 81/225 = 9/25
Answer: 9/25
--------------------------------
Part 4:
The probability of rolling a 6 is 1/6. The probability of rolling a 3 is 1/6 as well. This is because there is only one side with this label out of 6 total. Multiply the probabilities
(1/6)*(1/6) = 1/36
Answer: 1/36
--------------------------------
Part 5:
It is impossible to roll a 7 on the six sided cube because the highest number is 6. Therefore the overall probability is 0
Answer: 0
--------------------------------
Part 6:
There are 3 outcomes we want (rolling a 1,2, or 3) out of 6 total. So the probability of rolling a 1,2 or 3 is 3/6 = 1/2. Similarly, the probability of rolling a 4, 5 or 6 is 3/6 = 1/2 as well.
Multiplying the probabilities gives
(1/2)*(1/2) = 1/4
Answer: 1/4
B is the corrrect answer hope it helps
