Answer:
![Ratio = 7:6](https://tex.z-dn.net/?f=Ratio%20%3D%207%3A6)
Step-by-step explanation:
Given
Initially
-- coffee
-- coffee
Joe drank 2oz coffee; So, we have:
![Joe = 12oz - 2oz](https://tex.z-dn.net/?f=Joe%20%3D%2012oz%20-%202oz)
--- coffee
Joe added 2oz cream; So, we have:
--- coffee
--- cream
JoAnn added 2oz cream and stirred. So, we have:
--- coffee
--- cream
![Total = 14oz](https://tex.z-dn.net/?f=Total%20%3D%2014oz)
JoAnn drank 2oz from the drink; the amount of drink JoAnn drank is:
![JoAnn = \frac{Cream}{Total}](https://tex.z-dn.net/?f=JoAnn%20%3D%20%5Cfrac%7BCream%7D%7BTotal%7D)
![JoAnn = \frac{2}{14}](https://tex.z-dn.net/?f=JoAnn%20%3D%20%5Cfrac%7B2%7D%7B14%7D)
![JoAnn = \frac{1}{7}](https://tex.z-dn.net/?f=JoAnn%20%3D%20%5Cfrac%7B1%7D%7B7%7D)
Amount of cream left is:
![Amount = [1- \frac{1}{7}] *2](https://tex.z-dn.net/?f=Amount%20%3D%20%5B1-%20%5Cfrac%7B1%7D%7B7%7D%5D%20%2A2)
Take LCM
![Amount = [\frac{7-1}{7}] * 2oz](https://tex.z-dn.net/?f=Amount%20%3D%20%5B%5Cfrac%7B7-1%7D%7B7%7D%5D%20%2A%202oz)
![Amount = \frac{6}{7} * 2oz](https://tex.z-dn.net/?f=Amount%20%3D%20%5Cfrac%7B6%7D%7B7%7D%20%2A%202oz)
![Amount = \frac{12}{7}oz](https://tex.z-dn.net/?f=Amount%20%3D%20%5Cfrac%7B12%7D%7B7%7Doz)
So, we have:
--- cream
cream
The ratio is:
![Ratio = 2:\frac{12}{7}](https://tex.z-dn.net/?f=Ratio%20%3D%202%3A%5Cfrac%7B12%7D%7B7%7D)
Multiply by 7
![Ratio = 14:12](https://tex.z-dn.net/?f=Ratio%20%3D%2014%3A12)
Divide by 2
![Ratio = 7:6](https://tex.z-dn.net/?f=Ratio%20%3D%207%3A6)

Answer: 22.5% chance
Step-by-step explanation:
The number of students in total is 40 and 9 kids have chosen to play tag. 9 divided by 40 is .225 then we would multiply .225 with 100 to make it a percent.
Answer:
(a) is true
Step-by-step explanation:
Given
See attachment for box plots
Required
Which of the options is true?
Option A compares the IQR of both plots.
IQR is calculated using:
![IQR = Q_3 - Q_1](https://tex.z-dn.net/?f=IQR%20%3D%20Q_3%20-%20Q_1)
Where
Lower quartile
Upper quartile
From the attached plots, we have:
Republican
![Q_1 = 170.5](https://tex.z-dn.net/?f=Q_1%20%3D%20170.5)
![Q_3 = 356](https://tex.z-dn.net/?f=Q_3%20%3D%20356)
So:
![IQR = 356 - 170.5](https://tex.z-dn.net/?f=IQR%20%3D%20356%20-%20170.5)
![IQR = 185.5](https://tex.z-dn.net/?f=IQR%20%3D%20185.5)
Democratic
![Q_1 = 181](https://tex.z-dn.net/?f=Q_1%20%3D%20181)
![Q_3 = 367.5](https://tex.z-dn.net/?f=Q_3%20%3D%20367.5)
So:
![IQR = 367.5 - 181](https://tex.z-dn.net/?f=IQR%20%3D%20367.5%20-%20181)
![IQR = 186.5](https://tex.z-dn.net/?f=IQR%20%3D%20186.5)
We have:
--- Republican
--- Democratic
<em>Hence, (a) is true</em>
Its C , a negative association because it is going from the top left to the bottom right which is knows as a negative association/negative correlation , hope this helps
