miskamm [114]

Answer:

720

Step-by-step explanation:

because 8% of 9000$ is 720$.

another way.

Step 1: Our output value is 9000.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$9000=100$.

Step 4: Similarly, $x=.8%$.

Step 5: This results in a pair of simple equations:

$9000=100%(1)$.

$x=.8%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

Step 7: Again, the reciprocal of both sides gives

Therefore, 8%of $9000$ is $720

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
