Answer:
28
Step-by-step explanation:
The binomial coefficient is calculated as:
![nCx=\frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=nCx%3D%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
It means that there are nCx ways to select x elements from a group of n elements.
So, If the researcher wants to determine the probability that 6 out of the next 8 individuals in his community are in favor of the president, we can replace n by 8 and x by 6 and calculated the binomial coefficient as:
![8C6=\frac{8!}{6!(8-6)!}=28](https://tex.z-dn.net/?f=8C6%3D%5Cfrac%7B8%21%7D%7B6%21%288-6%29%21%7D%3D28)

Answer:
To find the slope you find the change in y axis and divide by the change in x
ie
(y-4 ) ÷ (x-3)
Answer:
4X + 30 = TOTAL AMOUNT OF MONEY
Step-by-step explanation:
All of them bought a ride ticket (that explains the 4x)
3 of them also bought a game pass thet costs $10 each. That explains the 30
<em>going deeper</em>: If the total amount of money was $70
The tickets would've costed $10 each.
Look:
4x + $30 = $70
4x = 70 - 30
4x = 40
x = 40/4
x =$10
