Option D:
The solution to the equation is y = 27.
Solution:
Given equation:
![$\frac{1}{3} y=9](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20y%3D9)
To solve this equation:
![$\frac{1}{3} y=9](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20y%3D9)
Multiply by 3 on both sides of the equation.
![$3 \times \frac{1}{3} y=9 \times 3](https://tex.z-dn.net/?f=%243%20%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%20y%3D9%20%5Ctimes%203)
3 in the numerator and denominator get canceled.
y = 9 × 3
y = 27
The solution to the equation is y = 27.
Option D is the correct answer.
Answer:
![P(Green\ or\ Red) = 0.30](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%200.30)
Step-by-step explanation:
Given
![White = 40](https://tex.z-dn.net/?f=White%20%3D%2040)
![Green = 24](https://tex.z-dn.net/?f=Green%20%3D%2024)
![Red = 12](https://tex.z-dn.net/?f=Red%20%3D%2012)
![Yellow = 24](https://tex.z-dn.net/?f=Yellow%20%3D%2024)
![Blue = 20](https://tex.z-dn.net/?f=Blue%20%3D%2020)
Required
![P(Green\ or\ Red)](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29)
The total numbe of candy is:
![Total = 40 + 24 + 12 + 24 + 20](https://tex.z-dn.net/?f=Total%20%3D%2040%20%2B%2024%20%2B%2012%20%2B%2024%20%2B%2020)
![Total = 120](https://tex.z-dn.net/?f=Total%20%3D%20120)
This probability is calculated as:
![P(Green\ or\ Red) = P(Green) + P(Red)](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%20P%28Green%29%20%2B%20P%28Red%29)
For each, we have:
![P(Green\ or\ Red) = \frac{Green}{Total} + \frac{Red}{Total}](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%20%5Cfrac%7BGreen%7D%7BTotal%7D%20%2B%20%5Cfrac%7BRed%7D%7BTotal%7D)
Take LCM
![P(Green\ or\ Red) = \frac{Green+Red}{Total}](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%20%5Cfrac%7BGreen%2BRed%7D%7BTotal%7D)
![P(Green\ or\ Red) = \frac{24+12}{120}](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%20%5Cfrac%7B24%2B12%7D%7B120%7D)
![P(Green\ or\ Red) = \frac{36}{120}](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%20%5Cfrac%7B36%7D%7B120%7D)
![P(Green\ or\ Red) = 0.30](https://tex.z-dn.net/?f=P%28Green%5C%20or%5C%20Red%29%20%3D%200.30)
