Answer:

Hope it helps!

Step-by-step explanation:

Last year there were 74 students in the seventh grade class. This year there are 86 students in the seventh grade class.

Increase = 86 - 74 = 12

Percent Increase = (12/74) x 100 = 16.2%

The measure of the angle JKL as per the attached diagram is equal to 97 degrees.

As per in the question,

Diagram is attached.

Angle JKL is linear pair angle with given angle of measure 83 degrees.

Sum of the pair of linear pair is always equal to 180 degrees.

Let 'x' be the measure of angle JKL, we get,

83° + m ∠JKL = 180°

Subtract 83° from both the side of the equation we get,

⇒ 83° - 83° + m ∠JKL = 180° - 83°

⇒ m ∠JKL = 97°

Therefore, the measure of the angle JKL as per the attached diagram is equal to 97 degrees.

When the scale factor is greater than 1, the dilation is an enlargement.

We have to explain, what happens when you apply a scale factor greater than 1.

The pre-image and image have the same shape after dilatation, but they are not the same size.

The figure is the same from every perspective. The midpoints of the figure's sides and the dilated shape's midpoint are both unchanged.  Lines that are parallel and perpendicular to one another in the figure are identical to those in the dilated figure. The pictures stay the same.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation.

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

Answer:

Tom is 164 years old and Bob is 3*164-82=246 years old.

Step-by-step explanation:

Let X be Tom's age.

Bob's age is 3X-82.

The difference in their ages is X-(3X-82)=2(3X-82)

Solving for X, we get X=164.

Tom is 164 years old and Bob is 3*164-82=246 years old.

Thus, we get regression equation as 7.5 =ý - 0.9x

Regression analysis is a group of statistical procedures used in statistical modeling to calculate the associations between a dependent variable and one or more independent variables.

Here,

The points are given as:

Xi: 2; 6; 9; 13; 20

Yi: 7; 18; 9; 26; 23

From the table of values, we have:

ΣEx=2+6+9+13+ 20 = 50

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]

So, we have:

b=[tex]\frac{1001 - \frac{50}{83} }{690^{2} -\frac{50^{2} }{5} }[/tex]

b = 0.9

The y-intercept (a) is calculated as:

a =ý - bx

Where

y' =Σy/n =83/5=16.6

x'=Σx/n=50/5 =10

So we get ,

a=16.5 * 9*10

a=7.5

Thus, we get regression equation as 7.5 =ý - 0.9x

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.

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.

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)

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

y = 2/3x + b

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).

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
