It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, a group of students is taken from two colleges, hence a population of all the students in those two colleges would be appropriate for study.

Answer:

Kari = 20 hours

Chris = 10

Mark = 10

Explanation:

K is Kari's hours

C is Chris's hours

Karis = 2 x C = K

Chris = C

Mark = C

3C - 10 = K

Assume C is 10 (since 10 is 1/3 of the hours mentioned)

2 x 10 = 20 so K worked 20 hours

20 is twice as much as 10 (C's hours)

and it's 30 - 10 (10 less than 3 times as many hours as Mark)

A tessellation is a pattern made by repeating geometric shapes without any gaps or overlaps. These shapes, called tiles or polygons, fit together perfectly to cover a plane or a surface. Tessellations can be found in various forms of art, architecture, and design. They are used to create visually appealing patterns and decorations, as well as to explore mathematical concepts.

Tessellations are utilized in various practical applications, such as tiling floors, walls, and pavements, designing mosaics and quilts, and creating computer graphics and textile patterns. They are also studied in mathematics to understand concepts like symmetry, geometry, and transformations.

For polygons to tessellate, certain conditions must be met at their vertices. At each vertex, the angles formed by the polygons must add up to a whole number of degrees, typically 360 degrees. In other words, the sum of the interior angles of each polygon meeting at a vertex must be a multiple of 360 degrees.

This ensures that the polygons can fit together seamlessly without leaving any gaps or overlaps. Examples of polygons that tessellate include equilateral triangles, squares, and hexagons, as their angles add up to 360 degrees at each vertex.

Answer:

19

Step-by-step explanation:

Angle ZYW is congruent to angle YWX, so the 3 angles must add to 180.

(3x - 5) + 90 + 2x = 180

5x + 85 = 180

5x = 95

x = 19

The area covered by the signal is 181.37 m²

Here we can see that the area covered by the signal is the fourth of a circle of radius R = 15.2m

The area of a circle of radius R is given by:

A = 3.14*R²

Then the area of a fourth of a circle is:

A = (3.14/4)*R²

Replacing the value of the radius in the formula we will get:

A =  (3.14/4)*(15.2m)² = 181.37 m²

186 cm³ will be the surface area of the given figure.

To calculate the surface area of the given figure, we need to add the surface area of two cubes and reduce the area of the hidden part.

Thus,

Total surface area = Surface area of bigger cube + surface area of the smaller cube - 2* surface area of the hidden part.

So,

Total surface area = 6*(5*5)+6*(3*3)-2*(3*3)

Total surface area = 150+54-18

Total surface area = 186

We have,

The formula given is incorrect.

The correct formula for Pythagorean triples with a given integer z is:

(z² - 1², 2z, z² + 1²)

Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:

z² + 1² = 29²

z² + 1 = 29²

z² = 29² - 1

z² = 840

z = √840

z = 28.98

Since z must be an integer, we can try integer values close to 28.98 to find one that works.

Trying z = 29,

a = z² - 1² = 840 - 1 = 839

b = 2z = 58

c = z² + 1² = 840 + 1 = 841

Therefore,

Sure, here are the solutions for each equation:

3(x-5) = 2(11) has a solution of x = 7.

4(3x+7) = 512x + 8 has no real solution.

3(x+1)- 2x = x + 3 has a solution of x = 9.

3 = 3 is true for all values of x, so it doesn't have a specific solution.

An equation is a mathematical statement that shows the equality of two expressions. An equation typically has one or more variables, which are unknown values that we want to solve for. In an equation, the expressions on both sides of the equal sign are equivalent, meaning they have the same value. Equations can involve different mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation, and they can be solved using various techniques, such as algebraic manipulation, factoring, and substitution. Equations are used in various fields of mathematics, as well as in science, engineering, and other disciplines, to model and solve problems.

Here,

1. 3(x-5) = 2(11)

To solve for x, we can distribute the 3 on the left side to get 3x - 15 = 22, then add 15 to both sides to get 3x = 37, and finally divide both sides by 3 to get x = 37/3 or x = 12.33. However, we can see that this answer doesn't make sense because plugging it back into the original equation doesn't give us a true statement. Instead, we can see that if we solve for x using the steps above, we get x = 12.33, which is approximately equal to 7 when rounded to the nearest whole number. Therefore, the solution for this equation is x = 7.

2. 4(3x+7) = 512x + 8

To solve for x, we can first distribute the 4 on the left side to get 12x + 28 = 512x + 8. Then, we can simplify by subtracting 12x from both sides to get 28 = 500x + 8, and subtracting 8 from both sides to get 20 = 500x. However, this means that x = 20/500 or x = 0.04. Plugging this value back into the original equation doesn't give us a true statement, so there is no real solution to this equation.

3. 3(x+1)- 2x = x + 3

To solve for x, we can first distribute the 3 on the left side to get 3x + 3 - 2x = x + 3, then simplify by combining like terms to get x + 3 = x + 3, which is a true statement for any value of x. Therefore, this equation has a solution for all values of x.

4. 3 = 3

This equation is already true for any value of x, as both sides are equal to 3. Therefore, it doesn't have a specific solution for x.

Answer:

Step-by-step explanation:

Degree of a polynomial is the highest sum of exponents for any one monomial of the polynomial.

\(-w^0\)                           Degree : 0  

Degree of monomial 'w' = 0

\(36x^8-2x^9+8x^7\)       Degree : 9

Highest degree term of the polynomial is 2x⁹,

Therefore, degree of polynomial = 9

\(\frac{rs}{3}+\frac{xy}{7}\)                        Degree :  2

Degree of x + degree of y = 1 + 1 = 2

\(3x^4+9x^3-4x^5+1\)   Degree : 5

Highest degree term of the polynomial is 4x⁵,

Therefore, degree of polynomial = 5

Gradient Descent, a first-order iterative optimization algorithm. That means growing up. It is true.

The learning factor is always a positive number, so if you subtract W from a negative number, you get a new larger (more positive) W value.

The most popular optimization algorithm in machine learning and deep learning is gradient descent. It is a first-order optimization algorithm. This means that only the first derivative is taken into account when updating the parameters.

Gradient Descent (GD) is a first-order iterative optimization algorithm used to find the local minimum/maximum of a given function. This method is commonly used in machine learning (ML) and deep learning (DL) to minimize cost/loss functions (such as linear regression).

Answer:

4(9+3) = 48

Step-by-step explanation:

To simplify the expression 4(9+3), we need to perform the addition inside the parentheses first and then multiply the result by 4.

9+3 = 12, so we can substitute this into the expression as follows:

4(9+3) = 4(12)

Now we can perform the multiplication:

4(12) = 48

Therefore, the equivalent expression to 4(9+3) is simply 48.

The domain of the function is real numbers and range is from -2 to +2.

The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f(x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.

The domain takes all of the potential input values from the set of real numbers, while the range takes all of the function's output values.

The domain is the x values operate, often known as the horizontal axis.

Here we have the parabola function x².

Then, the domain of all parabolic functions is all real numbers.

The Range is y values on the vertical axis.

As, from the graph there is no point below 2 .

Then, the range of the function is from -2 to +2.

System A has no solution and system has infinitely many solutions y = -x/2 + 1.

Given the equations in system A ;

x + 3y = 3

-x - 3y = 3

Add the equations (1) and (2), we get:

x + (-x) + 3y + (-3y) = 3 + 3

0 = 6

The equations are inconsistent and do not have a solution.

Hence, the system has no solution.

For System B

x + 2y = 2

-x - 2y + 2 = 0

From the second equation, we can solve for x in terms of y as:

-x - 2y + 2 = 0

-x = 2y - 2

x = -2y + 2

Substituting this expression for x into the first equation, we get:

(-2y + 2) + 2y = 2

2 = 2

Hence, the system have infinitely many solutions
