An even function is symmetric about the y-axis. If a function is symmetric about the origin, it is odd.
Let A be a matrix which is both symmetric and skew symmetric. so AT=A and AT= -A so A =- A that implies 2A =zero matrix that implies A is a zero matrix
A relation ~ is symmetric ifX ~ Y if and only if Y ~ X.This may seem trivial, but it is easy to see that "is less than" or "is a factor of" are not symmetric.
If it is a symmetric distribution, the median must be 130.
