#### Median of an even set

##### Median of an even set

Is it true that when the number of terms in a set is even, then it canâ€™t be concluded that 50% of terms are greater/less than or equal to the median?

###### Problem Solving

In the equation x^2âˆ’7x+n=0, n is a constant and x is a variable. Is (xâˆ’6) a factor of x^2âˆ’7x+n=0? (1) n=6 (2) (xâˆ’1) is a factor of x2âˆ’7x+n=0. Ans: D But for 1) if we put n=6 into the equation wouldn't that yield 2 different values for x? namely x=6 or x=1? So why's this statement sufficien...
