I am not sure how to show you how to do a dot plot on this website, but to see how to do a dot plot
b) Put everything in order and find the middle 10, 10, 10, 20, 30, 30, 30, 30, 40, 50, 50, 50, 60, 60, 70, 70, 2040 ^^ So 40 is in the middle, making it the median
c) Add all of the values together and divide by the total number of values. 10 + 10 + 10 + 20 + 30 + 30 + 30 + 30 + 40 + 50 + 50 + 50 + 60 + 60 + 70 + 70 + 2040 = 2660 2660 / 17 = 156.5
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24. x^2 + z^2 = 13^2 y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231 now y = 24-x so we have
