Goshia [24]
 1.              x -    4
x - 6|x² - 10x + 24
     - (x² -  6x)
               -4x + 24
             - (4x + 24)
                          0
The answer is C.

2. A. 9x² + 12x - 3
        3(x²) + 3(4x) - 3(1)
        3(x² + 4x - 1)

    B. 9x² + 3x - 5
        Not Factored

    C. 6x² + 10x - 4
        2(3x²) + 2(5x) - 2(2)
        2(3x² + 5x - 2)
        2(3x² + 6x - x - 2)
        2(3x(x) + 3x(2) - 1(x) - 1(2))
        2(3x(x + 2) - 1(x + 2))
        2(3x - 1)(x + 2)

    D. 6x² + 7x - 6
         Not Factored

The answer is C.

3.                  3x³ - 4x² + 3x - 6
   x + 2|3x⁴ + 2x³ - 5x² + 0x - 4
         - (3x⁴ + 6x³)
                     -4x³ - 5x²
                  - (-4x³ - 8x²)
                               3x² + 0x
                            - (3x² + 6x)
                                       -6x - 4 
                                    - (-6x - 12)

Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviat
drek231 [11]

Answer:

E(X) = \sum_{i=1}^n X_i P(X_i) = 0*0.031 +1*0.156+ 2*0.313+3*0.313+ 4*0.156+ 5*0.031 = 2.5

We can find the second moment given by:

E(X^2) = \sum_{i=1}^n X^2_i P(X_i) = 0^2*0.031 +1^2*0.156+ 2^2*0.313+3^2*0.313+ 4^2*0.156+ 5^2*0.031 =7.496

And we can calculate the variance with this formula:

Var(X) =E(X^2) -[E(X)]^2 = 7.496 -(2.5)^2 = 1.246

And the deviation is:

Sd(X) = \sqrt{1.246}= 1.116

Step-by-step explanation:

For this case we have the following probability distribution given:

X          0            1        2         3        4         5

P(X)   0.031   0.156  0.313  0.313  0.156  0.031

The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.

The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).  

We can verify that:

\sum_{i=1}^n P(X_i) = 1

And P(X_i) \geq 0, \forall x_i

So then we have a probability distribution

We can calculate the expected value with the following formula:

E(X) = \sum_{i=1}^n X_i P(X_i) = 0*0.031 +1*0.156+ 2*0.313+3*0.313+ 4*0.156+ 5*0.031 = 2.5

We can find the second moment given by:

E(X^2) = \sum_{i=1}^n X^2_i P(X_i) = 0^2*0.031 +1^2*0.156+ 2^2*0.313+3^2*0.313+ 4^2*0.156+ 5^2*0.031 =7.496

And we can calculate the variance with this formula:

Var(X) =E(X^2) -[E(X)]^2 = 7.496 -(2.5)^2 = 1.246

And the deviation is:

Sd(X) = \sqrt{1.246}= 1.116
