The likelihood that the first question will be true is equally likely and unlikely.

Step-by-step explanation:

Using addition, the total amount of sugar sold equals  13 16/20 Kg .

The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum.

We add numbers in many different contexts.

The combination of at least two numbers constitutes basic addition. Once a student has mastered counting, they can begin to study basic addition.

By locating the addend at the top of the chart and tracing down to the row of the second addend, they can utilize an addition chart as a learning tool.

Given,

shopkeeper sold 7 3/4 kg, 2 1/2 and 3 3/5 of sugar to three customers in a day

Using addition,

⇒ 7 3/4 kg + 2 1/2 + 3 3/5

⇒ 31/4 + 5/2 + 18/5

⇒ 155 + 50 + 72 / 20

⇒ 277/20

⇒ 13 13/20 Kg

Three-fifths is equivalent to 6/10.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let the number of fifth be = x

So,

(1/5)x = 6/10

Now,

Solve for x.

(1/5)x = 6/10

x = (6 x 5) / 10

x = 30/10

x = 3

Answer:

Step-by-step explanation:

You want the end behavior of the graphed line.

The end behavior of a graphed function is found by looking at the arrows on the ends of the graph. If the arrow points in a direction with positive slope, the sign of the function value (y) will match the sign of the independent variable (x).

If the arrow has negative slope, then the signs of the end behaviors will be opposite.

If the arrow points horizontally or vertically, then the end behavior will be an asymptote. The function value will approach the value of a horizontal asymptote. The function value will tend to infinity (up: +∞; down: -∞) as the independent variable approaches the location of the vertical asymptote.

Here, the line has positive slope everywhere, so the sign of y will match the sign of x as both go to ±∞.

__

Additional comment

Slope is positive if the sign of the "rise" matches the sign of the "run". A line that goes down to the left has positive slope, just as does a line that goes up to the right. (Right and up are positive directions.)

The experimental probability of landing on a number greater than 4 is 0.25 or 25%.

To find this probability, we need to determine the number of successful outcomes (landing on a number greater than 4) and divide that by the total number of trials (60).

The successful outcomes are 5 and 6, with a frequency of 10 and 8 respectively. To add these two frequencies together, we can use 10 + 8 = 18.

So, the experimental probability is 18/60 = 0.3 or 25%.

It's important to note that experimental probability is based on the outcomes of an experiment or a sample and it may not be the same as a theoretical probability which is based on the ratio of favorable outcomes to the total number of outcomes in a theoretical model.

Como la cuerda está formando un ángulo de 30 grados con la horizontal, la componente de la fuerza en la dirección de la cuerda se calcula utilizando el coseno del ángulo: 86.6 N.

Para calcular el valor de la normal y la fuerza de rozamiento, primero debemos calcular la componente de la fuerza de gravedad que actúa en dirección perpendicular a la superficie de apoyo. La componente de la gravedad en dirección perpendicular se calcula utilizando el seno del ángulo formado por la cuerda con la horizontal (30º):

F_normal = F_grav * sen(30º)

Donde F_grav es la fuerza de gravedad del cuerpo, que se calcula como:

F_grav = m * g

Donde m es la masa del cuerpo (40 kg) y g es la aceleración debida a la gravedad (9.8 m/s²)

Por lo tanto,

F_normal = (40 kg) * (9.8 m/s²) * sen(30º) = 392 N

La fuerza de rozamiento se calcula utilizando la fórmula:

F_fric = μ * F_normal

Donde μ es la coeficiente de rozamiento estático entre el cuerpo y la superficie de apoyo. Como no se especifica el valor del coeficiente de rozamiento, no se puede calcular la fuerza de rozamiento.

La tensión en la cuerda es igual a la fuerza neta en la dirección de la cuerda. Como la cuerda está formando un ángulo de 30 grados con la horizontal, la componente de la fuerza en la dirección de la cuerda se calcula utilizando el coseno del ángulo:

T = F * cos(30º) = 100 N * cos(30º) = 86.6 N

The formulas of closure property is

where a, b and R are real numbers.

In mathematics, the Closure property can be defined as when an arithmetic operation is performed on any two numbers from a set and the result obtained is a number from the set itself, it is considered closed.

Closure property of addition : The closure property of an integer says that when we add two real numbers, the result will always be a real number. The formula for this is written as

a + b = R; where a, b and R are real numbers.

For example, 6 + 13 = 19 ; (1/3) + (5/2) = 17/6

Closure property under multiplication: The product of two real numbers is always a real number, that is, real numbers are closed under multiplication. The formula, ab = R , where a, b, and R are real numbers. For example, 9 × 0 = 0

(3/4) × (-1/4) = -3/16, √3 ×√5 = √15.

The Closure Property of Subtraction states that if any two real numbers a and b are subtracted from each other, the difference or result will also be a real number. For example, 9 - 4 = 5. This property is only applicable to integers and rational numbers.

Answer:

Choice B

Step-by-step explanation:

Function is g(x) = x² - 2

Domain is the possible set of x values and range is the set of function values for that domain

Here Domain = {- 2, - 1, 7}. This means these are values for which the function value g(x) exists

(Note this is not the entire domain, only a subset of the domain)

At x = - 2, g(x) = (-2)² - 2 = 4 - 2 = 2

At x = - 1, g(x) = (-1)² -2 = 1 -2 = -1

At x = 7, g(x) = (7)² -2 = 49 - 2 = 47

These are the corresponding range values for the given domain

Both domain and range sets are expressed from lowest to highest so we get range of g(x) as

Length of Carla's living room is 20 feet

Step-by-step explanation:

The perimeter of a rectangle is 2(L + W)
In the case of both dining and living rooms, we are given the widths as dining room width = 18, living room width = 12 and asked to calculate living room length from the information given

Let x be the length of the dining room and y the length of the living room

Perimeter of dining room = 2(18 + x)

Perimeter of living room = 2(12 + y)

Since these are equal
2(18 + x) = 2(12 + y)

=> 18 + x = 12 + y

Subtract x from both sides:
18 = 12 + y - x

Subtract 12 from both sides:
18 - 12 = y - x

Simplifying and rearranging terms we get

- x + y = 6  [1]

We are also given that:
The length of her dining room is 1 foot less than 3/4 the length of her living room.

This mathematically translates to:
[tex]x = \dfrac{3}{4}y - 1[/tex]

which can be re-written as

[tex]x - \dfrac{3}{4} = -1 \; \cdots[2][/tex]

So the two equations are

[tex]- x + y = 6 \;\cdots [1][/tex]

[tex]x - \dfrac{3}{4}y = - 1 \; \cdots [2][/tex]

Notice that the coefficients of x are the same(1) but with opposite signs

Add [1] and [2]

[tex](-x + y) +(x - \dfrac{3}{4}y) = 6 - 1\\\\-x + x + y - \dfrac{3}{4}y = 5\\\\\dfrac{1}{4}y = 5\\\\y = 20\\\\[/tex]

So the length of the living room is 20 feet

(If you wanted to find the length of the dining room, substitute 20 into equation 1 to get -x + 20 = 6 which will give x = 14 and is the length of the dining room)

An algebraic expression (or) a variable expression is a combination of terms by operations such as addition, subtraction, multiplication, and division. For example, let's look at the expression 5x + 7.

Algebraic Expression:

Algebraic expressions are mathematical expressions that result when you perform operations such as addition, subtraction, multiplication, and division on variables and constants. For example, let's say James and Natalie were playing with matches and wanted to create a pattern of numbers in matches. James played four games and formed No. 4. Natalie added three more games and two he formed a pattern of four. They realized they could add 3 matches to each round to get an extra '4'. From this, they concluded that, in general, 4 + 3 (n-1) double crochet stitches are required to create n 4 patterns. Here 4+ 3(n-1) is called an algebraic expression. To solve a linear equation with one variable, use the transpose method. Follow this procedure to perform the same operations on both sides of the equal sign. That is, perform operations to isolate variables.

Example:

5x + 7 = 32

Subtract 7 from both sides

⇒ 5x = 25

Divide both sides by 5

⇒ x = 5

⇒ 5x = 25

Divide both sides by 3

⇒ 2y – 12 = 24

Add 12 to both sides

⇒ 2y = 36

Divide both sides by 2

To find the direction and magnitude of the resultant of these three forces, we can use the law of cosines and the law of sines.

First, we need to resolve each force into its x and y components using trigonometry.

F1x = 80 * cos(30) = 69.28

F1y = 80 * sin(30) = 40

F2x = 95 * cos(45) = 67.08

F2y = 95 * sin(45) = 67.08

F3x = 125 * cos(120) = -62.5

F3y = 125 * sin(120) = -106.6

Then we can find the x and y components of the resultant force by adding the x and y components of each force respectively.

Rx = F1x + F2x + F3x = 69.28 + 67.08 - 62.5 = 74.86

Ry = F1y + F2y + F3y = 40 + 67.08 - 106.6 = 0.48

Finally, using these values we can use the law of cosines to find the magnitude of the resultant force:

R = sqrt(Rx^2 + Ry^2) = sqrt(74.86^2 + 0.48^2) = sqrt(5633.79) = 75.24

And we can use the law of sines to find the direction of the resultant force:

theta = atan2(Ry, Rx) = atan2(0.48, 74.86) = 0.01

Therefore, the magnitude of the resultant force is 75.24 pounds and the direction of the resultant force is 0.01 degrees.

The log equation [tex]\text{x} = \log_b(\text{y})[/tex] is equivalent to its exponential form [tex]\text{y} = b^\text{x}[/tex]

For the exponential equation, we can replace x with any real number. We don't have to worry about things like dividing by zero. Therefore the domain of the exponential equation is "set of all real numbers".

The domain of  [tex]\text{y} = b^\text{x}[/tex] is the range of [tex]\text{x} = \log_b(\text{y})[/tex]. The domain and range swap roles when going from original to inverse.

Therefore, the range of any logarithmic function is "set of all real numbers".
