\ \ \ 5 \ (-\frac{1}{5} a = 10 - b) \\ + (2a = 5b -20) \\ \\ a = 30

5× the first equation + the second equation will give an equation of 'a' to its value.

By comparing medians which person went to the movies the most per month
Nimfa-mama [501]

I think they all went to the movies equally per month if you simply compare medians? Since in the second chart, they each have a median of 2 times per month, that makes it equal. If you aren’t sure if this is correct, you have to order how many times each person went to the movies, from least to greatest. For example, John’s would be 1,1,1,2,2,2,2,3,3,3,4,5. Then you would start crossing numbers off from each end. First you would cross off 1, then 5, and then 1, and then 4, and keep going until you reach the number in the very middle, which is 2. Do this with all of the other people, and check if everybody has 2 for a median. I believe they do, however it’s always best to check and be safe. Good luck

If lateral surface area of cube is double then the ratio of volume of new cube to original cube ​
Solnce55 [7]

Answer:

  2√2

Step-by-step explanation:

The area ratio is the square of the side length ratio, so the ratio of side lengths is √2.

The volume ratio is the cube of the side length ratio, so the new cube has a volume that is (√2)³ times that of the original.

The volume ratio is 2√2.
