The measure of the angle HBG found using the trigonometric ratio for cosines is about 27.266°

The trigonometric ratios is the set of relationships between the interior angles of a right triangle and the ratios of the lengths of two of the sides of the right triangle.

The measure of the size of the angle HBG, can be obtained from the specified lengths of the sides of the triangle ΔHBG and the trigonometric ratios as follows;

Length of BH = 27

Length of BG = 24

In the plane ABGH, the side BH is perpendicular to the side GH, therefore;

ΔHBG is a right triangle, where;

The hypotenuse side = BH

BG = The leg of the right triangle that is the adjacent side to the angle HBG.

The trigonometric ratios of the cosine of an angle is the ratio of the adjacent side to the angle to the hypotenuse of the right triangle.

[tex]cos(\theta) = \dfrac{Adjacent}{Hypotenuse}[/tex]

Therefore;

[tex]cos(\angle HBG) = \dfrac{24}{27}[/tex]

[tex]\angle HBG = arcos\left(\dfrac{24}{27}\right) \approx 27.266^{\circ}[/tex]

Demand in economics refers to a consumer's readiness to pay a particular price for goods and services as well as their desire to buy them. Demand for a good or service typically declines when its price goes up. Demand describes the consumer's desire and willingness to purchase a good or service at a specific time or over an extended period of time. Additionally, consumers must be able to afford the items they want or need based on their budgeted disposable income. Demand therefore has an impact on market expansion and economic growth.

True. When we add a whole number to another whole number, the result is always a whole number.

This is called the closure property of addition.

A whole number is a set of all positive integers from 0 to infinity. Also, these numbers in their simplest fractional form will have a denominator of 1. This means no numbers after decimal point.

Example 1 If we add 34 and 67

34 + 67

= 101

Hence 101 is a whole number.

Example 2- If we add 54 and 450

54 + 450

= 504

From the definition, we can say that 504 is a whole number.

The required slope (m) is -12 when the points given are (-3, 4) and (-3, -8).

In mathematics, a line's slope, also known as its gradient, is a mathematical expression of the line's steep slopes and orientation.

A line's steeper can be identified by looking at its slope.

The slope was calculated mathematically as "rise over run" (change in y divided by change in x).

So, the slope formula is:
m = y2 - y1/x2 - x1

Now, substitute the values and calculate the slope as follows:

m = y2 - y1/x2 - x1

m = -8 -4/-3+3

m = -12/0

m = -12

Therefore, the required slope (m) is -12 when the points given are (-3, 4) and (-3, -8).

Slope-Intercept form: y = mx + b

Leave y and x as variables as it is easier for graphing.

m is the slope, or how much the y-value changes every timer the x-value increases by 1.

b is the y-intercept, or the x-value of the line when it has a x-value of 0 (when it hits the y-axis.)

Question

Using this information, lets first find the slope.

To find the slope, we can use the slope formula. Use any two sets of points to plug into the formula.

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

I'll use the points:

(3, -4)

and

(6, -2)

Because they are marked.

Plug in your two y-values into the numerator and two x-values into the denominator.

[tex]\frac{-2 - - 4}{6 - 3}[/tex]

2/3

So, we have 2/3 as a slope. We can start writing the equation in slope-intercept form.

y = 2/3x + b

To solve for b, we can either examine the graph or solve it algebraically. However, if the graph is more complex we can't just look at it.

Answer:

75% of the number is equal to 50

Step-by-step explanation:

To find 75% of a number, we can multiply the number by 0.75. To find the number, we can first use the equation 15% * x = 10 to find what 15% of the number is equal to. Then we can divide both sides of the equation by 0.15 to find the value of x.

Here's how we can solve this problem:

First, let's set up the equation that represents the problem: 15% * x = 10

Next, we can divide both sides of the equation by 0.15 to find the value of x:

(15% * x) / 0.15 = 10 / 0.15

This simplifies to:

x = 10 / 0.15

Finally, we can multiply x by 0.75 to find 75% of the number:

0.75 * x = 0.75 * (10 / 0.15)

This simplifies to:

0.75 * x = 50

Therefore, 75% of the number is equal to 50

Answer: 49.95

Step-by-step explanation:

15%/100%=0.15

The percent is the same as 0.15

0.15x=10

x= 66.6

0.75*66.6= 49.95

The coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).

What is transformation of points?

The reflection is the kind of transformation that takes place whenever a shape's points cross a line. When the points are reflected over a line, the image is on the opposite side of the line from the pre-image and is located at the same distance from the line. The image point is reflected from each point (p, q).

Given:

Quadrilateral ABCD has coordinates A(−2, 0), B(0, 4), C(4, 6), and D(2, 2).

First to find the coordinates after applying the transformation  

(x, y) ⟶ (–x, y).

So,

A(-2, 0) ⟶ A'(2, 0)

B(0, 4) ⟶ B'(0, 4)

C(4, 6) ⟶ C'(-4, 6)

D(2, 2) ⟶ D'(-2, 2)

Now applying the transformation (x, y) ⟶ (x, –y)

A'(2, 0) ⟶ A"(2, 0)

B'(0, 4) ⟶ B"(0, -4)

C'(-4, 6) ⟶ C"(-4, -6)

D'(-2, 2) ⟶ D"(-2, -2)

Hence, the coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).

Answer:

To prove that FAB is congruent to ECD, we need to show that they have the same size and shape. Since ABCD is a parallelogram and FBED is a parallelogram, we know that opposite sides of these figures are parallel and equal in length. This means that AB is parallel to ED and is equal in length to ED. Similarly, FB is parallel to DC and is equal in length to DC. Therefore, FAB is congruent to ECD because they have the same size and shape.

Another way to prove this is to use the fact that a diagonal of a parallelogram divides the parallelogram into two congruent triangles. In this case, the diagonal AC of the parallelogram ABCD divides it into two congruent triangles, namely triangles ABC and ACD. Similarly, the diagonal BE of the parallelogram FBED divides it into two congruent triangles, namely triangles BEF and BED. Since triangles ABC and BEF are congruent, and triangles ACD and BED are congruent, we can conclude that FAB is congruent to ECD because they are both composed of two congruent triangles.

Regression analysis using the logistic regression, regression model best fits the description of the data.

When modeling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method (also known as dependent and independent variables). Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables. As opposed to multivariate linear regression, which predicts numerous correlated dependent variables as opposed to a single scalar variable, this phrase is more specific.

When modeling relationships with linear predictor functions, the model's unknown parameters are inferred from the data.

The logistic regression method can be used in situations when the dependent variable is discrete. In other words, the likelihood of situations like pass/fail, true/false, 0/1, and so on that are mutually incompatible are calculated using this method. A sigmoid curve depicting the relationship between the independent variable and the target variable, which can only take on one of two values, and probability, which has a value between 0 and 1, are both present.

Here,

The points are given as:

Xi: 2; 6; 9; 13; 20

ΣEy = 7+18+9+26+23=83

Also, we have:

ΣExy = 2 x 7+ 6 x 18+9x9+13 × 26 +20 × 23: 1001

ΣEx² = 22 +6² +92 +13² +20² = 690

ΣEy² =72 +18² +9² +26² +23² =1659

The slope (b) is calculated as:

b=[tex]\frac{x - \frac{xy}{D} }{x^{2} -\frac{x^{2} }{n} }[/tex]
