The option D is the correct option.

According to the statement

we have to define the sample variance in the words.

The sample variance is the sum of the squared deviations from the mean divided by the number of measurements minus one.

and in the case of the population variance it becomes

The population variance is the average of the squared distances of the measurements on all units in the population from the mean.

Based on the graph how many real number solutions to the equation X^3+6x^2+12x+8=0have
Igoryamba

ANSWER

One real root.

EXPLANATION

The graph of the function

f(x) =  {x}^{3}  +  6{x}^{2}  + 12x + 8

is shown in the attachment.

According to the Fundamental Theorem of Algebra, this function must have 3 roots including real and complex roots.

The x-intercepts gives the number of real roots.

Observe that the graph has only one intercept.

This implies that, the equation:

{x}^{3}  +  6{x}^{2}  + 12x + 8 = 0

has only one real solution.
