Answer:

2(x +1/2)^2 = -1/2

Step-by-step explanation:

The steps generally will be ...

1. subtract the constant

2x^2 +2x = -1

2. factor out the leading coefficient on the left

2(x^2 +x) = -1

3. add the square of half the x-coefficient inside parentheses, and an equal quantity on the other side of the equal sign

2(x^2 +x +1/4) = -1 +2(1/4)

4. simplify and write in the required form

2(x +1/2)^2 = -1/2

11. x squared - 7x = 0 12. 3x squared - 4x = 20x + 27
Stella [2.4K]
11. x² - 7x = 0
      x(x) - x(7) = 0
      x(x - 7) = 0
      x = 0    or    x - 7 = 0
                           + 7 + 7 
                               x = 7

Solution Set: {0, 7}

12. 3x² - 4x = 20x + 27
           + 4x   + 4x
             3x² = 24x + 27
      3x² - 24x - 27 = 0
      x = -(-24) ± √((-24)² - 4(3)(-27))
                              2(3)
       x = 24 ± √(576 + 324)
                         6
       x = 24 ± √(900)
                     6
       x = 24 ± 30
                 6
       x = 4 ± 5
       x = 4 + 5    or    x = 4 - 5
       x = 9    or    x = -1

Solution Set: {9, -1}

Leya [2.2K]
For a binomial distribution, the variance is
\sigma^2=npq=np(1-p)=10*0.7*0.3=2.1
\sigma=standard\,deviation=\sqrt{2.1}=1.449 (to 3 decimal places)
