Marie made the box plot below to display a set of data. Which set of data could the box plot represent?
Assoli18 [71]

Answer:

  see below

Step-by-step explanation:

First of all, you want to find the data set the matches the extreme values of 5 and 35. That eliminates the 2nd and 4th choices.

Then you want to find the data set that has a median of 15. The first data set has a middle value (median) of 20, so that choice is eliminated.

The data set of the 3rd choice matches the box plot extremes, median, and quartile values.

Solve for x: 6x – 8y = 12
Tcecarenko [31]

Hi there!


Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.


6x + 8y = 12


Step 1) Add 8y to both sides.


6x - 8y + 8y = 12 + 8y 6x = 8y + 12


Step 2) Divide both sides by 6.


\frac{6x}{6} =  \frac{8y + 12}{6}


x =  \frac{4}{3} y + 2


Final Answer -


x =  \frac{4}{3} y + 2


Hope this helps! :D
