Hi, can you tell me why is my top belly is hard and the botton is soft?
How is it that if you have a set of data, x1,y1....xn,yn with a known linear relationship between x & y (y = mx + c), and the best straight line fit MUST go through xbar,ybar (xbar average of all x values, ybar is average of all y values).
How old are you? it could be a fibroid tumor. ( don't worry they aren't cancerous or dangerous) my mom had one awhile ago and got it removed. If it really bugs you go to the doctor they will know what is best. :)
