The discussion revolves around a user seeking urgent help with two statistics questions due tomorrow. They express confusion about determining the midpoint for the 31-40 and 41-50 intervals, questioning whether certain values are accurate. Additionally, they discuss their approach to assessing symmetry in a dataset, noting that they adjusted values to achieve a symmetric appearance. The user also critiques the presentation of a graph, suggesting it is poorly drawn and resembles a staircase. Overall, the user is looking for clarity and confirmation on their interpretations and calculations.

Hello Everyone!
I really need help on 2 questions and it is due tomorrow! So please help me when u can and ASAP

So for this one, this was easy, except for the 31-40 interval I'm not sure if it's 4.5, cause it's not necessarily exactly between and half of 4 and 5 and for the 41-50 interval I'm not sure if its actually a 3 and its somewhat confusing. Does anyone care to enlighten me?

For this one, I am also confused. For my answer I believe it is approximately symmetric, you know what I did? So I did like what you usually do I add and replace the bars so all of them can look symmetric,
and then for the last one it stays as 12 and if I break/divide it by 2, you get 6, and that will be perfectly symmetric. The thing is I don't know if my thesis is correct.
PLEASE KINDLY
HELP ME ASAP

I would say that the first one is just drawn badly! They did NOT have a fractional number of players on the floor! There were 2+ 1+ 4+ 3= 10 players.

For the next one, I have no idea what they mean by "shape"! I would probably say that this graph is shaped like a staircase!
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
