Answer:
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.
Answer:

so the answer would be c.
Step-by-step explanation:
The discriminant is the following equation:

You just simply plug in the values of the coefficients.

a = 1 (first terms coefficient)
b = -2 (second terms coefficient)
c = 5 (last terms coefficient)

No solutions in real numbers. So <u>D.</u>
