First one A thats the answer
I believe that it is 2 because you have 1 line with 3 plots meaning 1.2.3 and the dots could represent rays.
hope this helps otherwise let me know.

Using Algebra I have concluded that the answer is 12.5 kilometers per liter. :D
First set up your equation
![\frac{8}{100} = \frac{1}{x} \\\\Next multiply by x (\frac{8}{100})x = (\frac{1}{x})x \\\\](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B100%7D%20%3D%20%5Cfrac%7B1%7D%7Bx%7D%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3ENext%20multiply%20by%20x%20%3C%2Fp%3E%3Cp%3E%28%5Cfrac%7B8%7D%7B100%7D%29x%20%3D%20%28%5Cfrac%7B1%7D%7Bx%7D%29x%20%5C%5C%5C%5C)
![(\frac{8x}{100}) = 1\\\\](https://tex.z-dn.net/?f=%28%5Cfrac%7B8x%7D%7B100%7D%29%20%3D%201%5C%5C%5C%5C)
Then multiply by 100
![(\frac{8x}{100}) 100 = (1) 100](https://tex.z-dn.net/?f=%28%5Cfrac%7B8x%7D%7B100%7D%29%20100%20%3D%20%281%29%20100)
![8x = 100\\\\Finally divide by 8\frac{8x}{8} = \frac{100}{8}](https://tex.z-dn.net/?f=8x%20%3D%20100%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EFinally%20divide%20by%208%3C%2Fp%3E%3Cp%3E%5Cfrac%7B8x%7D%7B8%7D%20%3D%20%20%5Cfrac%7B100%7D%7B8%7D)
![x = 12.5](https://tex.z-dn.net/?f=x%20%3D%2012.5)
Hope this helps!
Answer:
0.509
Step-by-step explanation:
Given that a random sample of 1016 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?"
Of the 1016 adults surveyed, 517 indicated that televisions are a luxury they could do without.
To find out the point estimate of population proportion of adults in the country who believe that televisions are a luxury they could do without.
We find that point estimate is nothing but sample proportion
Sample proportion = favourably voters/total people surveyed
= ![\frac{517}{1016} \\=0.5088\\=0.509](https://tex.z-dn.net/?f=%5Cfrac%7B517%7D%7B1016%7D%20%5C%5C%3D0.5088%5C%5C%3D0.509)
