What is structural model?

The items in the system and the static relationships that connect them make up the structural model. Packages or subsystems can be used to divide up groups of items. The structural model is described in object model diagrams. The code that is produced from object model diagrams is described in this section.

It looks like the question you provided contains multiple parts and is discussing the use of instrumental variables (IVs) in regression analysis.

An instrumental variable (IV) is a variable that is correlated with the independent variable in a regression model, but is not correlated with the error term. It is used to estimate the effect of the independent variable on the dependent variable, while controlling for omitted variables that may be correlated with both the independent and dependent variables.

In the question, y2 is the dependent variable, z1 is the endogenous explanatory variable (i.e., the independent variable that is correlated with the error term), and z2 and z3 are the exogenous explanatory variables that are excluded from the model. The reduced form equation for y2 is an equation that expresses y2 as a function of the exogenous explanatory variables and the error term.

The least restrictive assumption we need to impose on the T parameters in order for the instrument y5 to not be perfectly correlated with z1 is T2 + 0 and T3 # 0. This means that the effect of y5 on y2 must not be perfectly correlated with the effect of z1 on y2.

Step-by-step explanation:

The circumference of a circle is equal to \(\pi\) times the length of the diameter of the circle (\(\pi\) is a constant which is approximately equal to 3.14).

The Area of the shaded portion is: 72 square inches

The formula for the area of a triangle is given by the formula:

Area = ¹/₂ * base * height

Now, to get the area of the shaded portion, we will get the area of the larger triangle and subtract the area of the smaller one from it.

Thus:

Area of larger triangle = ¹/₂ *  17 * 13 = 110.5 square inches

Area of smaller triangle =  ¹/₂ * 11 * 7 = 38.5 square inches

Thus:

Area of shaded portion = 110.5 square inches - 38.5 square inches

Area of shaded portion = 72 square inches

Nonlinear functions can have curves, bends, or other complex shapes when plotted on a graph.

Nonlinear functions are mathematical functions that do not follow a straight line when graphed on a coordinate plane. Unlike linear functions, which have a constant rate of change, nonlinear functions exhibit varying rates of change and do not have a constant slope.

Nonlinear functions can take various forms, such as quadratic functions, exponential functions, logarithmic functions, trigonometric functions, and many more. These functions can have curves, bends, or other complex shapes when plotted on a graph.

The key characteristic of nonlinear functions is that they do not have a constant ratio of change between the independent and dependent variables. Instead, the relationship between the variables can be more complex, involving powers, roots, or other mathematical operations.

Answer:

-5/6

Step-by-step explanation:

(9, 5) and (21, -5)

slope = m = (difference in y)/(difference in x)

m = (-5 - 5)/(21 - 9)

m = -10/12

m = -5/6

Answer: -5/6

The slope of the line that passes through points (9,5) and (21,-5) is -5/6.

We can use the two-point formula to find the slope for the given line. The formula is as follows:

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

Where (x1, y1, x2, and y2) represent the points on the line, and m is the slope of the line.

In the given case:

x1=9, x2=21

y1=5, y2=-5

Using these values in the two-point formula, we get:

(-5-5)=m*(21-9)

-10=m*12

m=-10/12

m=-5/6

Hence the slope of the line is -5/6.

The weight of the male that has a body surface area of 2.3 would be = 108kg

The body surface area (BSA) is defined as the parameter that can be used to estimate the surface area of a person's body based on body weight and height.

The formula for BSA = √w×h/3600

The weight of the male = X

The height of the male = 176cm

The BSA = 2.3

From the formula, make w the subject of formula;

w = BSA²× 3600/h

w = 2.3²× 3600/176

w= 5.29×3600 /176

w = 19044/176

Answer:

also ,Check the attached graph

Step-by-step explanation:

let D₁ be the line of equation 3x - 9y = 36

    D₂ be the line of equation 2x - 6y = -8

In order to graph D₁ we need to find two point shot that lie on it.

→ If x = 0 , 3(0) - 9y = 36 ⇔ -9y = 36 ⇔ y = -4

Then the point C(0 , -4) lies on D₁

→ If x = 3 , 3(3) - 9y = 36 ⇔ -9y = 27 ⇔ y = -3

Then the point D(3 , -3) lies on D₁

Therefore,

D₁ is the line that connects the points C and D

Similarly,We can prove that the point she A(-4 , 0) and B(-1 , 1) lie on D₂

Then D₂ = (AB)

After graphing, we notice that D₁ and D₂ are parallel and they don’t have any point in common.

Therefore ,we say that’s the system is inconsistent

Answer:

See below.

Step-by-step explanation:

The given functions f(x) and g(x) are linear functions.  Therefore, their inverses are a reflection about the line y = x.

The mapping rule for reflecting a point about the line y = x is:

To determine if f(x) and g(x) are inverses of each other:

If the y-value of one function equals the x-value of the other function (and the x-value of one function equals the y-value of the other function), the functions are inverses of each other.

Given functions:

\(\begin{cases}f(x) = 2x+5\\\\g(x)=\dfrac{x-5}{2} \end{cases}\)

Ordered pair: (2, 9)

Substitute x = 2 into f(x):

\(\implies f(2)=2(2)+5=9\)

Substitute x = 9 into g(x):

\(\implies g(9)=\dfrac{9-5}{2}=2\)

Therefore, the functions are inverses of each other since the x-value of function f equals the y-value of function g, and the y-value of function f equals the x-value of function g.

Answer:

110/250

Step-by-step explanation:

If the fraction goal is 250 then put the 250 as the denomanator and the 110 as the top common denomanator.

Percentage of funds raised is 44 % , Fraction of funds raised is (11/25) and Fraction of funds raised in decimal form is 0.44.

To find the % of a number, divide it by its value, then multiply the result by 100. Percentage is a relative value that denotes one tenth of any quantity. As one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.

As per the given data:

In the diagram given, we can find the total amount of funds to be raised and the amount of fund which is raised currently.

Total amount to be raised = $250,000

Amount already raised = $110,000

Percentage of funds raised = (110,000/250,000) × 100 = 44 %

Fraction of funds raised = (110,000/250,000) = (11/25)

Fraction of funds raised in decimal form = 0.44

Hence, Percentage of funds raised is 44 % , Fraction of funds raised is (11/25) and Fraction of funds raised in decimal form is 0.44

The labeling of bases and height in a trapezium is not fixed and can vary based on the context or problem. It doesn't matter where they are on the trapezium, as long as they are clearly defined and consistent within the given situation.

In a trapezium (or trapezoid), the labeling of the bases and height is not fixed or standardized. It can vary depending on the context or the specific problem being considered. However, there are a few general guidelines to keep in mind when labeling a trapezium.

Bases: The trapezium has two parallel sides, often referred to as the "top base" and the "bottom base." The bases are usually labeled based on their relative lengths or position in the trapezium. The longer parallel side is commonly referred to as the "top base," while the shorter parallel side is referred to as the "bottom base." However, this is not a strict rule and can vary depending on the problem or preference.

Height: The height of a trapezium is the perpendicular distance between the bases. It is generally labeled as a vertical line segment connecting the bases. The placement of the height is not fixed, and it can be drawn from any point on the top base to any point on the bottom base, as long as it forms a perpendicular line. The height is usually labeled with the symbol "h" or sometimes "x" or "y" depending on the context.

It's important to note that the labeling of the bases and height is primarily for communication and clarity. As long as the labeling is consistent and clearly defined within the given problem or context, it does not have to conform to any specific arrangement or be in a rectangular shape. The key is to ensure that the labels are clearly understood and can be used to calculate the desired quantities or solve the problem at hand.
