What is you answer and how many solutions for the following 3r- 9=3(r + 3)

To divide 240g in the ratio 5:3:4, we need to find out the total number of parts of the ratio:

5 + 3 + 4 = 12

Now, we can find the value of one part of the ratio by dividing the total quantity by the total number of parts:

240g ÷ 12 = 20g

So, one part of the ratio is equal to 20g.

To find the quantities of each part of the ratio, we multiply the value of one part by the respective ratio number:

5 parts x 20g = 100g (for the first part)

3 parts x 20g = 60g (for the second part)

4 parts x 20g = 80g (for the third part)

Therefore, the quantities of 240g divided in the ratio 5:3:4 are 100g, 60g, and 80g respectively.

Therefore, the probability that a randomly selected family owns a cat is 0.257. Therefore, the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat is 0.778.

Probability is a branch of mathematics that deals with the study of random events or situations. It involves the quantification of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 representing impossibility and 1 representing certainty. The theory of probability provides a framework for making predictions, analyzing data, and making decisions in situations involving uncertainty or randomness.

Here,

Let's use the following events:

D: family owns a dog

C: family owns a cat

From the problem statement, we know:

P(D) = 0.3

P(C|D) = 0.2

P(C) = 0.34

1. To find the probability that a randomly selected family owns a cat, we can use the law of total probability:

P(C) = P(C|D) * P(D) + P(C|not D) * P(not D)

We don't know P(C|not D), but we can find it using the fact that P(not D) = 1 - P(D):

P(C|not D) = (P(C) - P(C|D) * P(D)) / P(not D)

P(C|not D) = (0.34 - 0.2 * 0.3) / (1 - 0.3)

P(C|not D) = 0.2857

Substituting the values:

P(C) = 0.2 * 0.3 + 0.2857 * 0.7

P(C) = 0.257

2. To find the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat, we can use Bayes' theorem:

P(not D|C) = P(C|not D) * P(not D) / P(C)

Substituting the values:

P(not D|C) = 0.2857 * 0.7 / 0.257

P(not D|C) = 0.778

After answering the presented question, we can conclude that triangle Therefore, the answer is A. 29 inches, since it falls within this range.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

The solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

Differential equations are used to model a wide variety of physical, biological, and economic systems, including the motion of objects under the influence of forces, the spread of disease in a population, and the behavior of financial markets.

There are many different types of differential equations, including ordinary differential equations (ODEs) and partial differential equations (PDEs). ODEs involve a single independent variable and its derivatives, while PDEs involve multiple independent variables and their derivatives.

To solve the differential equation dy/dx = 3x/√(y), we can separate the variables by multiplying both sides by √(y) and dividing both sides by 3x:

dy/dx = 3x/√(y)

√(y) dy/dx = 3x

√(y) dy = 3x dx

Integrating both sides:

∫√(y) dy = ∫3x dx

(2/3)*y^(3/2) = (3/2)*x² + C

where C is the constant of integration.

To find the value of C, we can use the initial condition (0,1), which means y=1 when x=0:

(2/3)*y^(3/2) = (3/2)*x² + C

(2/3)*1^(3/2) = (3/2)*0² + C

C = (2/3)

Substituting C = 2/3 back into the equation, we get:

(2/3)×y^(3/2) = (3/2) × x² + 2/3

y^(3/2) = (9/4) × x² + 1

y = ((9/4) × x² + 1)^(2/3)

Therefore, the solution to the differential equation dy/dx = 3x/√(y) with initial condition (0,1) is y = ((9/4) × x² + 1)^(2/3).

Answer:

Step-by-step explanation:

We can use the identity for the cosine of the sum of two angles:

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

In this case, we can write:

cos(60°) = cos(55° + 5°) = cos(55°)cos(5°) - sin(55°)sin(5°)

We know that cos(60°) = 1/2, and we also know that cos(55°) = p. We can solve for cos(5°):

1/2 = p cos(5°) - sin(55°)sin(5°)

sin(55°)sin(5°) = p cos(5°) - 1/2

We also know that sin²(55°) + cos²(55°) = 1, so:

sin²(55°) = 1 - cos²(55°) = 1 - p²

Substituting this into the previous equation:

(1 - p²)sin(5°)² = p cos(5°) - 1/2

Rearranging and factoring:

p cos(5°) = 1/2 - (1 - p²)sin(5°)²

Using the fact that sin²(5°) + cos²(5°) = 1, we can substitute cos²(5°) = 1 - sin²(5°):

p cos(5°) = 1/2 - (1 - p²)(1 - cos²(5°))

Simplifying:

p cos(5°) = 1/2 - (1 - p²) + (1 - p²)cos²(5°)

p cos(5°) = 1 - 2p² + (2p² - 1)cos²(5°)

Solving for cos²(5°):

cos²(5°) = (1 - p cos(5°) + 2p²) / (2p² - 1)

Substituting the value we found for p, cos²(55°) = p²:

cos²(5°) = (1 - p cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)

Finally, substituting p = cos(55°):

cos²(5°) = (1 - cos²(55°) cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)

cos²(5°) = (2cos²(55°) - cos²(55°) cos(5°) + 1) / (2cos²(55°) - 1)

cos²(5°) = (cos²(55°) + 1) / (2cos²(55°) - 1)

Therefore, the value of cos 5° in terms of p = cos 55° is:

cos 5° = ±sqrt[(cos²(55°) + 1) / (2cos²(55°) - 1)]

Note that the sign of the square root is determined by the quadrant in which 5° lies. Since 5° is in the first quadrant, cos 5° is positive.

The measure of angle ZUB is 32.8°.

A triangle is a closed, double-symmetrical object composed of three line segments known as sides that intersect at three points known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides.

Answer: wheres the question

Step-by-step explanation:

Step-by-step explanation:

The Victoria (Old Traffic) Bridge in Saskatoon, Canada, has a length of approximately 230 meters (755 feet). To estimate the length of the bridge in both SI and imperial units, you can use the following referents:

SI Units:

To estimate the length of the bridge in SI units, you can use meters as the referent. The length of the Victoria Bridge can be measured using a distance measuring device such as a surveyor's wheel, a laser distance meter, or a tape measure. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in meters.

Imperial Units:

To estimate the length of the bridge in imperial units, you can use feet as the referent. You can use a tape measure or a distance measuring wheel that measures in feet. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in feet.

To convert the length from meters to feet or vice versa, you can use the following conversion factors:

1 meter = 3.28 feet

1 foot = 0.3048 meters

Therefore, to convert the length of the Victoria Bridge from meters to feet, you can multiply the length in meters by 3.28. For example, 230 meters x 3.28 = 754.4 feet (rounded to the nearest tenth).

To convert the length of the Victoria Bridge from feet to meters, you can multiply the length in feet by 0.3048. For example, 755 feet x 0.3048 = 230.1 meters (rounded to the nearest tenth).

After answering the presented question, we can conclude that They are equation still pleased with the quantity of pizza they received, although it is less than in the previous scenario.

A quotient refers to the result obtained when one quantity is divided by another. For example, if you have 10 apples and you want to divide them equally among 2 people, each person would get 5 apples. The quotient in this case is 5, which represents the number of apples that each person would receive.

The quotient can be expressed in different forms, depending on the situation. If you are dividing two integers, the quotient can be a whole number (also known as an integer quotient) or a fraction (also known as a rational quotient). For example, if you divide 10 by 3, the quotient is 3 with a remainder of 1, which can be expressed as [tex]3 + 1/3[/tex] or as the fraction 10/3.

In algebra, the quotient can also refer to the result obtained when dividing two algebraic expressions. For example, if you divide [tex]x^2 + 3x + 2[/tex] by [tex]x + 1,[/tex] the quotient is [tex]x + 2[/tex], which represents the quotient of the division.

The concept of quotient is also used in other areas of mathematics, such as in modular arithmetic and in group theory, where it refers to the result of dividing one element of a group or a ring by another.

The two points on the line to graph the function is (0, -16) and (1, -53).

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. The order of the coordinates is crucial, and they are sometimes recognised by their position in an ordered tuple and occasionally by a letter, as in "the x-coordinate". In elementary mathematics, the coordinates are assumed to be real numbers, although they might instead be complex numbers or components of a more abstract system, such a commutative ring.

The given function is:

q(x)=3x−(2+5x)8

To find two points on the line to graph the function we substitute different values of x.

For x = 0:

q(x)=3x−(2+5x)8

q(0) = 3(0) - (2 + 5(0))8

q(0) = -16

For x = 1:

q(x)=3x−(2+5x)8

q(1) = 3(1) - (2 + 5(1))8

q(1) = 3 - (7)8

q(1) = -53

Hence, the two points on the line to graph the function is (0, -16) and (1, -53).

P(Male | Don't believe in ghosts) = P(Male and Don't believe in ghosts) / P(Don't believe in ghosts)

= 12/38

= 6/19

The surface area of the right square pyramid is 106. 25 m²

A square pyramid is seen as a pyramid with a square base.

If the apex is vertically above the center of the square, it is called a right square pyramid, and has four vertical symmetries.

Some properties of a right square pyramid are;

The formula for the surface area of a square pyramid is half of the product of its base perimeter and its slant height:

SA = P × l / 2

where P is the base perimeter and l is the slant height.

Substitute the values;

Surface area = 25(8.5)/2 = 212.5/2 = 106. 25 m²

After answering the given query, we can state that Therefore, we can function anticipate that 8 to 16 of the upcoming pastries will be bran muffins.

Mathematicians research numbers, their variations, equations, associated structures, shapes, and possible configurations of these. The relationship between a group of inputs, each of which has a corresponding outcome, is referred to as a "function." A function is a relationship between inputs and outputs where each input results in a unique, distinct output. Each function has a domain, codomain, or scope assigned to it. Functions are commonly denoted by the letter f. (x). An cross is entered. On functions, one-to-one capabilities, so several capabilities, in capabilities, and on functions are the four main categories of available functions.

We must determine the percentage of muffins that were bran muffins in the prior sales in order to determine how many of the subsequent 16 muffins sold would be bran muffins.

In the prior auction, the following amount of muffins were sold in total:

25 + 12 + 3 + 10 = 50

The percentage of muffins that were wheat muffins is as follows:

25/50 = 0.5

This indicates that wheat muffins accounted for 50% of all sales.

This ratio can be used to make a forecast about how many bran muffins will be sold over the course of the following 16 muffins. Therefore, we anticipate that roughly 50% of the subsequent 16 batches of muffins sold will be wheat muffins:

0.5 x 16 = 8

Therefore, we can anticipate that 8 to 16 of the upcoming pastries will be bran muffins.

Answer:

Step-by-step explanation:

C.

Answer: To solve the system of equations using the matrix method, we first need to set up the corresponding coefficient matrix and augmented matrix:

Coefficient matrix:

[1  4]

[2 -3]

Augmented matrix:

[1  4 | 9]

[2 -3 | 7]

To solve the system using matrix method, we perform row operations on the augmented matrix to get it into row echelon form, and then back substitute to obtain the solutions.

Performing row operations:

Multiply the first row by 2 and subtract the result from the second row:

[1  4 | 9]

[0 -11| -11]

Divide the second row by -11:

[1  4 | 9]

[0  1 | 1]

Subtract 4 times the second row from the first row:

[1  0 | 5]

[0  1 | 1]

The row echelon form of the augmented matrix is:

[1  0 | 5]

[0  1 | 1]

Therefore, the solution is x = 5 and y = 1.

So the solution of the system of equations is x = 5 and y = 1.
