Suppose that 28% of domestic adoptions are transracial, and that 84% of international adoptions are
transracial in the US. A social worker takes a SRS of 200 US adoptions, and in that sample, there are 160
domestic adoptions and 40 International adoptions. The social worker will then look at the difference
(1 - D) between the proportions of transracial adoptions in each sample,
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Choose 1 answer:
Approximately normal, because we expect 11,2 transpacial and 28.8 non-transracial domestic
adoption, and 134.4 and 25.6 international adoptions, and all of these counts are at least 10,
Approximately normal, because we expect 56 transracial and 144 non-transracial domestic
adoption, and 134.4 and 25.6 international adoptions, and all of these counts are at least 10,
Not normal, because we expect fewer than 10 non transradal international adoptions.
Not normal, because we expect fewer than 10 transracial domestic adoptions,

What is the height of the trapezoid?

Answer:

14k

Step-by-step explanation:

add 10 and 4 because they both have k

Answer:

40

Step-by-step explanation:

Try to get the variable alone by dividing 5/8 on both sides of the equations.

That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.

Answer:

40

Step-by-step explanation:

Multiply both sides by 8/5

Answer:

The statement is; True

Step-by-step explanation:

From the question, we have;

Rectangle ABCD is similar to Rectangle WXYZ

Therefore, rectangle ABCD can be obtained from rectangle WXYZ by multiplying by a scale factor given by the ratio of the corresponding sides of the two rectangles

Whereby side CD of rectangle ABCD is the corresponding side to side YZ of the rectangle WXYZ, we have;

The scale factor to obtain ABCD from WXYZ = CD/YZ

The scale factor for area is obtained by raising the scale factor of length to the power of 2

Therefore, the scale factor to obtain the area of rectangle ABCD from the rectangle WXYZ = (CD/YZ)²

∴ Area of ABCD = Area of WXYZ × (CD/YZ)²

From which we have;

(Area of ABCD)/(Area of WXYZ) = (CD/YZ)²

Therefore, the statement is true

Answer:

C, 8,634.86

Step-by-step explanation:

Starting with 8,591.69

2.51% of 8,591.69 is 215.651419

subtract that from 8,591.69 and you get 8376.038581

3.09% of 8376.038581 is 258.819592153

258.819592153+8376.038581=8634.85817315

8,634.86 is your final answer

Answer:

3060

Step-by-step explanation:

To solve this use this formula,

[tex]({n - 2}) \times 180[/tex]

where n is the number of sides of the shape.

There is 19 sides so

[tex](19 - 2) \times 180[/tex]

[tex]17 \times 180 = 3060[/tex]

3060 is the answer

Answer:

I would say B The x-intercept of function p is less than the x-intercept of function q. tell me if you got it right.

Step-by-step explanation:

The correct answer is option B. The x-intercept of function p is greater than the x-intercept of function q.

The x-intercept is where the curve represented by the equation cuts the x axis. At that point the ordinate should be 0.

[tex]log_{2} (x-1)=0[/tex]

⇒ x= 2

The x-intercept of p(x) is 2

2^x-1 = 0

⇒x= 0

The x-intercept of q(x) is 0

So, we can see the  x-intercept of p(x) is greater than x-intercept of q(x)

Answer:

122 degrees

Step-by-step explanation:

*A pentagon has a total of 540degrees

1st step: take all of the degrees and add them up:

105 + 90 + 86 + 137 = 418

2nd step: subtract the sum from 540:

540 - 418 = 122

The missing angle is 122 degrees

Answer:

∠ C = 122°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

Sum the given angles and equate to 540°

∠ C + 137° + 86° + 105° + 90° = 540 , that is

∠ C + 418° = 540° ( subtract 418° from both sides )

∠ C = 122°

Answer:

c=b

Step-by-step explanation:

b is not equal to c.

Answer:

$35 - 3b is greater or equal to $10

Step-by-step explanation:

Remember that:

     Dollars spent on an item = (cost of one item)*(number of items), so –

        Dollars spent on comic books = $3b

“Tracy has $35 to buy comic books and to pay for a movie ticket”   means

     (Money spent on comic books) + (money spent on movie ticket) ≤ $35

     (Money spent on comic books + $10 ≤ $35

                  $3b + $10 ≤ $35                           [just substituting values]

Now, we must modify the inequality, so remember the rules –

       $35 ≥ $3b + $10      [reverse right-to-left reverses the sense of the inequality;

             $35 is greater or equal to the total amount Tracy can spend]

       $35 - $3b  ≥ $10   [subtract positive 3b from both sides

                   keeps the sense of the inequality]

Answer: 3

Step-by-step explanation:

Take your equation x-1=2

Now put 3 in for x

3-1=2

2=2

x=3

Answer:

x = 3

Step-by-step explanation:

Substitute x for each answer until you get an answer equal to 2.

3 - 1 = 2

2 - 1 = 2

1 - 1 = 2

The only correct equation is 3 - 1 = 2, so 3 is x.

[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]

[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]

[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]

Step-by-step explanation:

Given

[tex](a)\ 15 * \frac{2}{5} = 6[/tex]

[tex](b)\ 6 * \frac{4}{3} = 8[/tex]

[tex](c)\ 16 * \frac{7}{8} = 14[/tex]

Required

Write 2 division equations

[tex](a)\ 15 * \frac{2}{5} = 6[/tex]

Express 15 as 15/1

[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]

Multiply numerator and denominator

[tex]\frac{30}{5} = 6[/tex] --- This is (1)

Multiply the fraction by a common term (e.g. 2)

So, we have:

[tex]\frac{30*2}{5*2} = 6[/tex]

[tex]\frac{60}{10} = 6[/tex] ---- (2)

[tex](b)\ 6 * \frac{4}{3} = 8[/tex]

Express 6 as 6/1

[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]

Multiply numerator and denominator

[tex]\frac{24}{3} = 8[/tex] --- This is (1)

Multiply the fraction by a common term (e.g. 4)

So, we have:

[tex]\frac{24*4}{3*4} = 8[/tex]

[tex]\frac{96}{12} = 8[/tex] ---- (2)

[tex](c)\ 16 * \frac{7}{8} = 14[/tex]

Express 16 as 16/1

[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]

Multiply

[tex]\frac{112}{8} = 14[/tex] ---- This is (1)

Divide the fraction by a common term (e.g. 4)

[tex]\frac{112/4}{8/4} = 14[/tex]

[tex]\frac{28}{2} = 14[/tex]
