Answer:
first you have to do 51 - 17 = 34 I got this because u have to add 10&7 then u subtract 51 from 17
6(-3-4y)
-18-24y
(Multiply 6 by both numbers)
Answer:I believe the answer is true but not 100% sure Hope this helped
Answer:
x = 13 1/2
Step-by-step explanation:
16x -12x+0=54
combine like terms
4x + 0 = 54
4x = 54
divide each side by 4
4x/4 = 54 /4
x = 54/4
x = 13 2/4
x = 13 1/2
Answer:
2.10% probability that the group will consist of all Republicans.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the members are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
Desired outcomes:
4 republicans from a set of 6.
![D = C_{6,4} = \frac{6!}{4!2!} = 15](https://tex.z-dn.net/?f=D%20%3D%20C_%7B6%2C4%7D%20%3D%20%5Cfrac%7B6%21%7D%7B4%212%21%7D%20%3D%2015)
Total outcomes:
4 members from a set of 6 + 7 = 13.
![T = C_{13,4} = \frac{13!}{4!9!} = 715](https://tex.z-dn.net/?f=T%20%3D%20C_%7B13%2C4%7D%20%3D%20%5Cfrac%7B13%21%7D%7B4%219%21%7D%20%3D%20715)
Probability:
![p = \frac{D}{T} = \frac{15}{715} = 0.021](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7BD%7D%7BT%7D%20%3D%20%5Cfrac%7B15%7D%7B715%7D%20%3D%200.021)
2.10% probability that the group will consist of all Republicans.
