Given the table below summarizes the grade earned by gender, let's determine the probability that the student is male given the student earned grade C.

Total Male 2 13 10 25 Female 5 19 14 38 Total 7 32 24 63 We can see from the table that 10 males earned grade C out of 24 students who earned grade C:P(Male | Grade C) = (number of males who earned grade C) / (total number of students who earned grade C)\(P(Male | Grade C) = 10/24 0.4167\) (rounded to four decimal places).

Therefore, the probability that the student is male given the student earned grade C is 0.4167.

A vector space is an abstract mathematical concept that is used to describe a collection of elements, known as vectors.

Vector is a mathematical object that has both magnitude and direction. It can be represented graphically by a line segment with a starting point and an endpoint. Vectors are used in physics, engineering, and mathematics to represent physical quantities such as force, velocity, and acceleration. They can also be used to represent geometric figures such as lines, points, and planes. Vectors are important in many applications, such as navigation, graphics, and robotics.

It is an important concept in linear algebra, and is used to describe the behavior of linear equations and systems.

A vector space is made up of a set of vectors, which can be seen as elements of the space. Each vector is a combination of scalar numbers, called components, and the space is made up of all possible combinations of these components. The components can be real numbers, complex numbers, or even functions.

The vector space is defined by certain operations, called vector addition and scalar multiplication. Vector addition is the process of adding two vectors together, and scalar multiplication is a process of multiplying a vector by a scalar number. Using these operations, the vector space can be used to solve linear equations and systems of equations.

The vector space is also used to describe the geometry of the space. It is used to describe dimensions, angles, and distances between vectors. It is also used to describe shapes and objects within the space, and to describe how they interact with each other.

Finally, the vector space is used to represent linear transformations, which are important in physics and engineering. A linear transformation is a process of mapping a vector to another vector, and is used to describe the behavior of physical systems. This can be used to solve complicated equations and systems of equations.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

the area of each piece of lawn is 18 square meters.

we can start by visualizing the lawn and the two paths that cross at a right angle. This creates four rectangular sections within the lawn.

Since the lawn is 16 meters long and 9 meters wide, we can use multiplication to find the total area of the lawn:

16 meters x 9 meters = 144 square meters

To find the area of each of the four identical pieces of lawn, we need to divide the total area by 4:

144 square meters ÷ 4 = 36 square meters

However, we also need to account for the two paths that cross the lawn. Each path is 2 meters wide, which means they take up a total of 4 square meters of space where they intersect. Since there are four sections of lawn, we need to subtract 1 square meter (the area of the intersection) from each section:

36 square meters - 1 square meter = 35 square meters

So the area of each piece of lawn is 35 square meters.

However, we still need to divide by 2 to account for the fact that the paths are overlapping in each section.

35 square meters ÷ 2 = 17.5 square meters

Since we are dealing with whole numbers, we can round up to get the final answer:

Each piece of lawn has an area of approximately 18 square meters.

the area of each piece of lawn is 18 square meters, after accounting for the two paths that cross at a right angle.

Let's analyze each relation and determine which properties are satisfied:

R1 = {(x, y) | x divides y}

1. Reflexivity: For any element x in N, (x, x) is in R1 if x divides itself. Since every number divides itself, R1 satisfies reflexivity.

2. Symmetry: If (x, y) is in R1, it means x divides y. However, this does not necessarily imply that y divides x. Hence, R1 does not satisfy symmetry.

3. Transitivity: If (x, y) and (y, z) are in R1, it means x divides y and y divides z. Since divisibility is transitive, x must divide z. Therefore, R1 satisfies transitivity.

4. Antisymmetry: Antisymmetry requires that if (x, y) and (y, x) are in R1, then x = y. In this case, if x divides y and y divides x, it means x = y. Therefore, R1 satisfies antisymmetry.

5. Irreflexivity: Irreflexivity states that for any element x in N, (x, x) is not in R1. However, R1 includes pairs where x divides itself, so it does not satisfy irreflexivity.

Summary for R1: R1 satisfies reflexivity, transitivity, and antisymmetry but does not satisfy symmetry or irreflexivity.

R2 = {(x, y) | x + y is even}

1. Reflexivity: Since x + x = 2x, which is even, (x, x) is in R2 for every element x in N. Therefore, R2 satisfies reflexivity.

2. Symmetry: If (x, y) is in R2, it means x + y is even. This also implies that y + x is even, so (y, x) is in R2. Therefore, R2 satisfies symmetry.

3. Transitivity: If (x, y) and (y, z) are in R2, it means x + y and y + z are even. Adding these two equations, we get x + y + y + z = x + z + 2y, which is even. Therefore, (x, z) is in R2, and R2 satisfies transitivity.

4. Antisymmetry: Antisymmetry requires that if (x, y) and (y, x) are in R2, then x = y. In this case, if x + y is even and y + x is even, it implies that x = y. Therefore, R2 satisfies antisymmetry.

5. Irreflexivity: Irreflexivity states that for any element x in N, (x, x) is not in R2. Since x + x = 2x, which is even, (x, x) is not in R2. Therefore, R2 satisfies irreflexivity.

Summary for R2: R2 satisfies reflexivity, symmetry, transitivity, antisymmetry, and irreflexivity.

R3 = {(x, y) | xy is even}

1. Reflexivity: For any element x in N, x * x = x^2, which is always even. Therefore, (x, x) is in R3 for every element x in N. Hence, R3 satisfies reflexivity.

2. Symmetry: If (x, y) is in R3, it means xy is even. This also implies that yx is even, so (y, x) is in R3. Therefore, R3 satisfies symmetry.

Answer:

x=4

Step-by-step explanation:

first you would factor the -2(2x-1). -2x2x= -4x, -2x-1= 2

the equation would then be 5x-4x+2=6

add the x's together which turns the equation to 1x+2=6

minus 2 from both sides of the equation which gives you x=4

The required value of x would be 4 in the given equation 5x − 2(2x − 1) = 6.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine the value of x in the equation

Given that the equations as :

⇒ 5x − 2(2x − 1) = 6

Open the parentheses and apply the multiplicative property,

⇒ 5x - 4x + 2 = 6

Apply the subtraction operation in the terms of x

⇒ x + 2 = 6

⇒ x = 6 - 2

⇒ x =  4

Therefore, the required value of x would be 4 in the equation

Therefore , as a result, the ratio of the corresponding sides of the triangle ABC and XYZ will be identical.

Since a triangle has four points or segments, it is regarded as a polygon. It is a fundamental geometric shape. A triangle with sides A, B, or C is referred to as triangle ABC. So when sides are not collinear, a single plane and square are generated in Euclidean geometry. If a triangle has three sides and three corners, it is a polygon. The corners of a triangle are the places where its three sides converge. The sum of the three triangle angles is 180 degrees.

Here,

A dilation is a modification that yields an image with a different size but the exact shape as the original. The initial figure can stretches or contracts by a specific amount.

The Law of Sines can be used to solve a triangle when two angles and a side opposite one of them is given.

third angle

The angle sum theorem can be used to find the third angle.

 C = 180° -A -B

    = 180° -30° -125°

    = 25°

The Law of Sines tells you ...

 a/sin(A) = b/sin(B) = c/sin(C)

 b = a(sin(B)/sin(A))

    = 38·sin(125°)/sin(30°)
