The polynomial p(x)=x^3-7x-6 has a non-factor of (x+1) rewrite p(x) as a product of linear factors.
In-s [12.5K]

Answer:

Using synthetic division suffices to answer your question:

Step-by-step explanation:

Synthetic division is the process by one reduces a large polynomial in your case x^3-7x-6 by a binomial in your case (x+1).

To do so one does the following:

\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0  \end{array}

Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:

(x^2-x-6)

Which can be factored in the following, and I will provide the complete factorization as well:

p(x)=(x+1)(x-3)(x+2)

A lightbulb is installed. With probability 1/3 , it burns out immediately when it is first installed. With probability 2/3 , it
Andrej [43]

Answer:

1 time unit

Step-by-step explanation:

There is a 1 in 3 chance that the time until the bulb burns out is zero, and a 2 in 3 chance that the time is the average between 0 and 3 (since it is uniformly distributed). Therefore, the expected value for the time until it burns is:

E(x) = \frac{1}{3}*0+\frac{2}{3} *\frac{0+3}{2}\\ E(X) = 1

The expected value of the time until the lightbulb burns out is 1 time unit.
