Masja [62]

Answer:

The mean is  \mu  = 2.1

Step-by-step explanation:

The mean number of employees calling sick per day can  be mathematically represented as

       \mu  = 0* 0.05 + 1 * 0.40 + 2 * 0.3 + 3 * 0.3 + 4*0.05

      \mu  = 2.1

Write x2 - 2x + 5 = 0 in vertex form. (Be sure to write your response in the form a(x-h)^2+k=0 with no spaces!)
Drupady [299]
To write the given quadratic equation to its vertex form, we first form a perfect square.
 
                x² - 2x + 5 = 0
Transpose the constant to other side of the equation,
                x² - 2x = -5
Complete the square in the left side of the equation,
              x² - 2x + (-2/1(2))² = -5 + (-2/1(2))² 
Performed the operation,
                x² - 2x + 1 = -5 + 1
Factor the left side of the equation,
               (x - 1)² = -4

Thus, the vertex form of the equation is,
          <em>  (x-1)² + 4 = 0</em>

Solve the absolute value equation<br> algebraically: 3|2x - 3| + 2 = 3
kupik [55]

Answer:

3 |2x - 3|  = 1

3 |2x - 3|  = 1 \\ 6x - 9 = 1 \\ 6x = 10 \\ x =  \frac{10}{6}  = \frac{5}{3}

3 |2x - 3|  =  - 1 \\ 6x - 9 =  - 1 \\ 6x = 8 \\ x =  \frac{4}{3}

x =  \frac{5}{3} x =  \frac{4}{3}

I am sorry but I am not sure of this :(
