The official poverty line of the United States, developed by Mollie Orshansky, is a measure used to determine the number and percentage of people living in poverty in the country. It sets a threshold income level below which individuals or families are considered to be in poverty.

The official poverty line of the United States was established by Mollie Orshansky in the 1960s. It is calculated based on a threshold income level that varies depending on the size and composition of a household. If a household's income falls below the threshold, they are considered to be living in poverty.

One reason the official poverty line is considered a good way to measure poverty is that it provides a standardized and consistent measure that allows for comparisons over time and across different regions. By using a specific income threshold, it allows policymakers, researchers, and organizations to track changes in poverty rates and develop targeted interventions to address poverty-related issues. It also enables the assessment of poverty trends and the evaluation of the effectiveness of anti-poverty programs.

While the official poverty line has its limitations, such as not accounting for regional variations in the cost of living or considering other factors like access to healthcare or education, it remains an important tool in understanding and addressing poverty in the United States.

Step-by-step explanation:

The measure of two supplementary angles =  15:21

The angles are  15x , 21x

15x + 21x = 180       {Supplementary}

         36x = 180

"Centripetal is the word used to describe a vector that always points toward the centre of a circular path."

The centripetal acceleration vector is an acceleration in the radial direction that is directed towards the centre of the circular line of motion. It runs perpendicular to the linear motion, or v.

The direction of the velocity shift for a ball travelling around a curve is in the direction of the curve's centre. Centripetal acceleration is the acceleration that is directed towards the centre of a curved or circular route.

Any force that changes the path of motion towards the centre of a circular motion is known as a centripetal force. The portion of the force that produces the centripetal force is the part that is perpendicular to the velocity.

To evaluate such, the following must be comprehended:

Slope: Rise/Run.

X-intercept: The peculiar point in which the observed linear data intersects the x-axis.

Y-intercept: The peculiar point in which the observed linear data intersects the y-axis.

To evaluate for the slope, which is defined as the agglomerate distance between two points contained within linear data, the following equation must be utilized:

m = (y2 - y1) / (x2 - x1)

Points utilized or given: (-1, 2) and (7, 2).

2 - 2 / 7 + 1 = 0/8 ==> 0

Henceforth, the slope for the particular configuration, as provided, is understood as zero (0).

Utilizing the integral of one of the points provided, as well as slope evaluated for, the following equation could be exploited:

Point-Slope Formula:

Y- y1 = m(x - x1)

Y - 2 = 0(x - 7)

Y - 2 = 0

Y = 2

Hence, the answer to the peculiar interrogate is disclosed as 2, which is identified as where the horizontal line intersects the y-axis at (0, 2).

Step-by-step explanation:

The perimeter of a rectangle is equal to 30.

The rectangle is a quadrilateral.  The classification for quadrilaterals is given by the length of sides and angles. For a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

A rectangle is a geometric figure that has 4 sides called: length and width (W). Due to its characteristics, the rectangle presents two length (L) and two widths (W).

The perimeter is the sum of all sides of a geometric figures. For a rectangle, the perimeter is 2L+2W.

The area for a rectangle is given by A=L*W.

The question gives:

From the area, you can find the width, see below.

A=L*W

A=2W*W

50=2W²

25=W²

5=W

If W=5, from condition length = 2*W, you can find the length. See

L=2*W

L=2*5

L=10

Therefore, the perimeter will be:

P=2L+2W

P=2*10+2*5

P=20+10

P=30

The morbidity rate is 500 cases per 100,000 people.

The morbidity rate is a measure of the number of cases of a particular disease within a specific population. In this scenario, out of 100,000 individuals exposed to the bacterial pathogen, 500 individuals develop the disease. Therefore, the morbidity rate is calculated by dividing the number of cases (500) by the total population (100,000) and multiplying by 100,000 to express it per 100,000 people.

Morbidity rate = (Number of cases / Total population) x 100,000

In this case, the calculation would be:

Morbidity rate = (500 / 100,000) x 100,000 = 500 cases per 100,000 people.

This means that for every 100,000 individuals exposed to the bacterial pathogen, there are 500 cases of the disease. The morbidity rate provides an important measure of the impact and prevalence of a disease within a population, allowing for comparisons and assessments of public health.

the formula for (f o g)(x) is Vx^3 + 12x^2 + 48x + 59, and it is simplified as much as possible.

To find the formula for (f o g)(x), we need to substitute g(x) into f(x) wherever we see x. So, we have:

(f o g)(x) = f(g(x))
= f(Vx+4)
= (Vx+4)^3 - 5

To simplify this answer, we can expand the cube of the binomial using the formula (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3. So, we get:

(f o g)(x) = Vx^3 + 12x^2 + 48x + 59


To find the formula for (f o g)(x), you need to substitute g(x) into f(x). Here's the solution:

Step 1: Identify f(x) and g(x).
f(x) = x^3 - 5
g(x) = √(x + 4)

Step 2: Substitute g(x) into f(x).
(f o g)(x) = f(g(x)) = (√(x + 4))^3 - 5

Step 3: Simplify the expression.
(f o g)(x) = (x + 4)^(3/2) - 5

So, the simplified formula for (f o g)(x) is (x + 4)^(3/2) - 5.

0.529 is the probability that a student does not have a college degree.

From the information given, we know that:

The formula for conditional probability:

P(A|B) = P(A and B) / P(B)

Let A be the event of not having a college degree, and B be the event of being married. We want to find P(A).

Using these values, we can calculate:

P(college degree and B) = (1/2) * (400/850) = 0.235

P(A and B) = 310/850 - 0.235 = 0.07

Finally, we can calculate P(A) using the formula for total probability:

P(A) = 1 - P(college degree)

= 1 - (400/850)

= 0.529

Therefore, the probability that a student does not have a college degree is 0.529.

a. The region of integration is the region between the curves\(y = x^4\)and \(y = x^2\), for 0 ≤ y ≤ 1.

b. The value of the integral is -0.6875.

To sketch the region of integration, we need to find the boundaries of the integral.

We are integrating with respect to x first, so we need to express the limits of integration for x in terms of y.

From the inner integral, we have:

y ≤ \(x^2\) ≤ √y

Taking the square root of both sides of the right inequality, we get:

\(y^{1/4}\) ≤ x ≤ √y

Thus, the region of integration is the region between the curves\(y = x^4\)and \(y = x^2\), for 0 ≤ y ≤ 1.

To sketch the region, we can first draw the curves \(y = x^4\) and \(y = x^2,\)as shown in graph (A) below:

  |          .

1  |       .  

  |    .  

  | .

    0  1  2  3

The region of integration is the shaded region between the curves, as shown in graph (B) below:

  |          +

1  |       +  

  |    +++  

  | +++        

  *------------>

    0  1  2  3

To evaluate the integral, we can use the boundaries we found and evaluate the integral using the following steps:

\(\int 1_0 \int y_(\sqrt{y } ) 110x^2y^3dxdy\)

\(= \int 0^1 \int x^{1/2}^x^2 110x^2y^3 dy dx\) (using the limits we found earlier)

\(= \int 0^1 110x^2 [(1/4)y^4]_(x^{1/2})^{x^2} dx\)  (integrating with respect to y)

\(= \int 0^1 110x^2 [(1/4)x^8 - (1/4)x^4] dx\) (substituting the limits of integration)

\(= \int 0^1 (27.5x^10 - 27.5x^6) dx\).

\(= [2.75x^11 - 3.4375x^7]_0^1\)(integrating and substituting limits)

= 2.75 - 3.4375.

= -0.6875.

The quadrilateral WXYZ is not a square using the distance formula

From the question, we have the following parameters that can be used in our computation:

W(-1,1),X(3,4),Y(6,0) and Z(2,3)

The lengths of the sides can be calculated using the following distance formula

Length = √[Change in x² + Change in y²]

Using the above as a guide, we have the following:

WX = √[(-1 - 3)² + (1 - 4)²] = 5

XY = √[(3 - 6)² + (4 - 0)²] = 5

YZ = √[(6 - 2)² + (0 - 3)²] = 5

ZW = √[(2 + 1)² + (3 - 1)²] = 13

The sides that are congruent are WX, XY and YZ

This means that WXYZ is not a square
