Answer:

6/35

Step-by-step explanation:

TO start you have to get a common denominator.

The lowest common multiple is 35, which just requires you to multiply the bottom two numbers to their fractions.

so you would do 3/5 times 7 on the top and bottom to get 21/35

then on the other one you would take 2/7 times 5 to get 15/35

you now have 21/35-15/25 or essentially 21-15 which is 6 and keep the denominator

you come out with 6/35

The number of combinations to define a 4-member committee will be 70.

Let 'x' be the number of things chosen out of 'n' number of things. Then the combination is given as,

ⁿCₓ = n! / [(n - x)! · x!]

And the permutation is written as,

ⁿPₓ = n! / [(n - x)!]

The committee of 4 people is chosen out of 8 people. Then the number of combinations is given as,

⁸C₄ = 8! / [(8 - 4)! · 4!]

⁸C₄ = (8 × 7 × 6 × 5 × 4!) / (4 × 3 × 2 × 1 × 4!)

⁸C₄ = (8 × 7 × 6 × 5) / (4 × 3 × 2 × 1)

⁸C₄ = 1680 / 24

⁸C₄ = 70

The number of combinations to define a 4-member committee will be 70.

We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.

Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.

We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:

288 / x² = (16*18) / x² = 288 / x²

Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.

As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

We can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.

To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.

The total area of the cake is:

16 inches x 18 inches = 288 square inches

To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:

√(288 square inches) ≈ 16.97 inches

Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:

Each piece of cake will be approximately 16 inches by 16 inches.

To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:

288 square inches ÷ (16 inches x 16 inches) = 18

Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

The value of SSE (sum squared error) is 40 in the given analysis of the variance problem if SST = 120 and SSR = 80. Option b is correct.

Here the words SSE means Sum Squared Error, SST means Sum of Squares Total and SSR means Sum of Square Regression.

In the SSE accuracy measure, errors are squared and then added. It is used when the data points are similar in magnitude.

The formula is SST = SSR + SSE ⇒ SSE = SST - SSR

The given values of the analysis of the variance problem are

SST = 120; SSR = 80

Then, the value of SSE = SST - SSR = 120 - 80 = 40

In this case, the slope of the line represents the rate of the hair cut, and the y-intercept represents the starting amount.

To calculate the rate of the hair cut at hair salon #2, we need to determine the slope (m) of the equation. To do this, we can use the two points of data given in the table. We will use the points (x1, y1) and (x2, y2). Using these points, we can calculate the slope of the line using the formula:

m = (y2 - y1) / (x2 - x1)

Using the data from the table, we get:

m = (30 - 20) / (2 - 1) = 10/1 = 10

Therefore, the equation for hair salon #2 is y = 10x + b

To calculate the y-intercept (b) of the equation, we can use any one of the points of data given in the table. Let's use the point (x1, y1) = (1, 20). We can then substitute this point into the equation:

It is true that in order to factor, it is useful to identify the greatest common factor (GCF). When a polynomial is factored, it is broken down into smaller parts that are then multiplied together. The GCF is the largest term that can be factored out of all the terms.

A polynomial with a GCF other than one is one that can be factored. Select all of the polynomials below that have a GCF other than one.In order to discover the GCF of these terms, we must first write them in a way that makes it easier to identify the common factors.2x + 8yThe GCF of this expression is 2.2x + 5yThe GCF of this expression is 1.2xy + 3xThe GCF of this expression is x.2yThe GCF of this expression is 2.2x² + 6xThe GCF of this expression is 2x.2x² + 3x + 6The GCF of this expression is 1.2x² + 4x + 6The GCF of this expression is 2.After reviewing all of the choices, only the first, fifth, sixth, and seventh have a GCF other than one.

When it comes to factoring polynomials, there are a variety of techniques. In order to factor, it is critical to start with the greatest common factor (GCF). This is the largest factor that all of the terms share. It is critical to identify this so that it can be removed and factored separately, simplifying the process. When a polynomial has a GCF of one, it cannot be factored further. When a polynomial has a GCF other than one, it can be factored down into simpler parts. For the polynomial 2x + 8y, for example, the GCF is 2. Each term can be divided by 2, resulting in x + 4y. The same is true for the polynomial 2x² + 6x, which has a GCF of 2x. This can be taken out, resulting in x + 3.

It is important to remember that to factor a polynomial, you must first identify the GCF. If a polynomial has a GCF of 1, it cannot be factored any further. If a polynomial has a GCF other than 1, it can be broken down into simpler parts, which makes the process of factoring much easier. It is critical to understand these basics before moving on to more complex factoring techniques.

In general, different refrigerants should not be mixed or recovered into the same cylinder.

Different refrigerants have unique chemical compositions and properties that make them incompatible with one another. Mixing different refrigerants can lead to unpredictable reactions, loss of refrigerant performance, and potential safety hazards. Therefore, it is generally recommended to avoid recovering different refrigerants into the same cylinder.

When recovering refrigerants, it is important to use separate recovery cylinders or tanks for each specific refrigerant type. This ensures that the refrigerants can be properly identified, stored, and recycled or disposed of in accordance with regulations and environmental guidelines.

The refrigerant recovery process involves capturing and removing refrigerant from a system, storing it temporarily in dedicated containers, and then transferring it to a proper recovery or recycling facility. Proper identification and segregation of refrigerants during the recovery process help maintain the integrity of each refrigerant type and prevent contamination or cross-contamination.

To maintain the integrity and safety of different refrigerants, it is best practice to recover each refrigerant into separate cylinders. Mixing different refrigerants in the same cylinder can lead to complications and should be avoided. Following proper refrigerant recovery procedures and guidelines helps ensure the efficient and environmentally responsible management of refrigerants.

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²
