Answer 1

Answer:

$D = 1$ --- Determinant

$M = \frac{N+1}{2}th$ --- Median

Step-by-step explanation:

Given

$5m^2 - m = 0$

Required

Calculate the determinant (D)

This is calculated using

$D = b^2 - 4ac$

In $5m^2 - m = 0$

$a = 5$, $b = -1$ and $c = 0$

So, we have:

$D = b^2 - 4ac$

$D = (-1)^2 - 4 *5*0$

$D = 1 - 0$

$D = 1$

(b) Median Formula.

Median (M) is calculated using:

$M = \frac{N+1}{2}th$ item
