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.

If the die were to be rolled 6000 times, would we expect to obtain exactly 1000 '2's? explain your answer.
ludmilkaskok [199]
The probability of that occurring is 0%. There are 6 sides in a typical dice, which means the probability of rolling a 2 is 1/6th. (1/6)^1000 will give you the probability of rolling a 2 exactly 1000 times. (1/6)^1000 equates to 0%.
