Step-by-step explanation:
Variance is the sum of squares of all items x from mean. i.e
Variance =
Being the sum of squares variance can never be negative irrespective of mean being negative.
Std deviation is the square root of variances. This will thus be less than variance if variance >1 other wise std deviation will be bigger than variance.
Hence option d is right.
check the picture below.
recall that a cube sides are all equal in length, and it's really just 6 squares stacked up to each other at the edges.
so if 600 is the total area of those 6 squares, then just for one is 600/6 in².
