Need now 76 points will mark brainliest answer plz answer all 2 ! and btw the 1st and second photos merge the same question

You should use the second graph!

I hope this helps!

For the first picture, use a bar graph. Line graphs are generally better for showing change over time.
For question number 50,  median is the middle of all inputs. Our inputs are
12,14,15,17,18,21,23,24,24,26,27,28,28,32,37.
Our median is 24.
24 is your answer
