babymother [125]

Answer:

1) 0.700

2) 0.730

3) 0.030

4) 0.959

Step-by-step explanation:

1) proportion of support for the ban with at least one child =

     \frac{no of support atleast 1 child}{Total no of atleast 1 child\\}

   = \frac{1739}{2485}

   = 0.700

2)  proportion of support for the ban with no child =

    = \frac{no of support with no child}{Total of no child}

    = \frac{3089}{4231}

    = 0.730

3) Difference in proportion of supporters for the ban between those with atleast one child and those with no child

    =  0.700 - 0.730

    = -0.03

4) Relative risk = \frac{proportion with atleast on child}{proportion with no child}

    = \frac{0.700}{0.730}  = 0.959

Find the value of c that completes the square
Kitty [74]

Answer:

c = 64

Step-by-step explanation:

Given

x² - 16x + c

To complete the square

add ( half the coefficient of the x- term )² to x² - 16x

x² + 2(- 8)x + 64

= (x - 8)²

Thus

x² - 16x + 64 = (x - 8)² ← a perfect square

with c = 64
