Answer:
Symmetry is correspondence of the form and arrangement of elements or parts on opposite sides of a dividing line. imagine that this ractangle is a piece of paper, you need to fold it two times, different ways. in this case when you fold it over the horizontal colored line all colored parts will match, same case when you fold it vertically.
For these questions, you would need to distribute the variables and coefficients
There are (15 + 13) = 28 students in Ms.Peterson's class.
13 of them are boys.
The probability of drawing a boy's name is
(boys) / (total) =
<em> </em> 13 / 28 = <em> 0.4643...</em> = 46.4% . (rounded)

slope = rise/run = 1/0 = undefined
you cannot divide by zero
