Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

\(3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}\)

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

\(\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}\)

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.

Answer:

A.

Step-by-step explanation:

The solution to the system of equations is (6.5, -2.5).

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To use the elimination method, we need to eliminate one of the variables by adding the equations.

Multiplying the second equation by 2, we get:

2x - 2y = 18

Now we can add the two equations:

2x + 3y = 8

(2x - 2y = 18)

4x = 26

Dividing both sides by 4, we get:

x = 6.5

Substituting x = 6.5 into the second equation, we get:

6.5 - y = 9

Solving for y, we get:

y = -2.5

Therefore,

The solution is (6.5, -2.5).

Step-by-step explanation:

The coordinate point at given x values are(-2, 8); (2, -4), (7, - 19) and the graph is given below.            

In mathematics, a graph is a visual representation of a set of objects, such as points, and vertices that are connected by links or edges. Graphs are used to analyze relationships between objects or variables.

Graphs can be used to represent many types of data, such as social networks, transportation systems, and chemical reactions. T

Here we have

f(x) = -3x + 2    

Let's take y = f(x)

At x = -2

=> y = -3(-2) + 2

=> y = 6 + 2

=> y = 8  

At x = 2

=> y = -3(2) + 2

=> y =  -6 + 2  

=> y = -4

At x = 7

=> y = -3(7) + 2

=> y = - 21 + 2

=> y = - 19    

Now use the coordinate points (-2, 8); (2, -4), and (7, - 19) to draw the graph as given below.

The probability of getting a sum of at least 3 when two different colored dice are rolled simultaneously is 5/6.

To calculate the probability of getting a sum of at least 3 when two different colored dice are rolled simultaneously, we need to list out all possible combinations of the dice and find out how many of them add up to at least 3. Let's begin:

Possible combinations when rolling two dice:

1 + 1, 1 + 2, 1 + 3, 1 + 4, 1 + 5, 1 + 62 + 1, 2 + 2, 2 + 3, 2 + 4, 2 + 5, 2 + 63 + 1, 3 + 2, 3 + 3, 3 + 4, 3 + 54 + 1, 4 + 2, 4 + 3, 4 + 55 + 1, 5 + 2, 5 + 36 + 1, 6 + 2, 6 + 3

Total number of combinations:

6 x 6 = 36.

Now, we need to find out how many of these combinations add up to at least 3.

We can ignore 1+1 because it's less than 3. The rest are as follows:

1 + 2, 2 + 1, 1 + 3, 3 + 1, 2 + 2, 1 + 4, 4 + 1, 2 + 3, 3 + 2, 1 + 5, 5 + 1, 2 + 4, 4 + 2, 3 + 3, 1 + 6, 6 + 1, 2 + 5, 5 + 2, 3 + 4, 4 + 3, 2 + 6, 6 + 2, 3 + 5, 5 + 3, 4 + 4, 3 + 6, 6 + 3, 4 + 5, 5 + 4, 4 + 6, 6 + 4, 5 + 5, 5 + 6, 6 + 5, 6 + 6.

Total: 30.

We need to find the inverse of the function gof (x). First we need to find the composite function gof (x) which is given by:

\(g(f(x)) = g(3x - 6)\)

= \((1/3)(3x - 6) + 1\)

= x - 1 + 1

= x

Thus,

gof (x) = x.

Now we need to find the inverse of the function gof (x) to obtain

\((gof)^-1 (x).\)

We have gof (x) = x

which implies\((gof)^-1 (x)\)

= gof (x)^-1

= x^-1

= 1/x,

x ≠ 0

Therefore,

\((gof)^-1 (x) = 1/x\)

Step-by-step explanation:

The equation y = 6x - 7 represents a straight line with a slope of 6, indicating a constant rate of change in the y-direction as x varies.

The rate of change in the given equation y = 6x - 7 can be determined by taking the derivative of y with respect to x. The derivative represents the instantaneous rate of change of y with respect to x at any given point.

To find the derivative of y = 6x - 7, we differentiate each term separately. The derivative of 6x with respect to x is simply 6 since the derivative of x^n (where n is a constant) is nx^(n-1). The derivative of -7 with respect to x is 0 since -7 is a constant.

Therefore, the derivative of y = 6x - 7 is dy/dx = 6.

This means that for every unit increase in x, the value of y increases by a constant rate of 6. The rate of change is constant and equal to 6 for all values of x.

In other words, the equation y = 6x - 7 represents a straight line with a slope of 6, indicating a constant rate of change in the y-direction as x varies.

The group that would be the most stable based on size would be 10 people. So, the correct answer is c. 10 people.

A group is a set of people or objects that are deemed to be equivalent or share a common feature. Group members may collaborate and share knowledge to achieve a common goal. The group's performance is frequently greater than the sum of its members' individual efforts, and this is known as the group effect.

Group stability is defined as the ability of a group to remain together and keep working toward its objective over time. It is essential for a group to achieve its objectives and is typically linked to the group's size and objective. A stable group can withstand external pressures and is less susceptible to breaking up or being disbanded.

A group's size has a significant influence on its stability. Small groups are often more cohesive and productive than large groups. On the other hand, as a group's size grows, it becomes more challenging to sustain cohesion and productivity. A group of 10 people would be the most stable since it's not too large or too small. Thus, the correct option is c. 10 people.

Answer:

12 feet 9 inches

Step-by-step explanation:

There are 3 feet in a yard, and 12 inches in a foot. Multiply those together and you get 36 inches in a yard.

2 yards × 36 inches/yard = 72 inches

2 feet × 12 inches/foot = 24 inches

72 inches + 24 inches = 96 inches

------------

7 yards × 36 inches/yard = 252 inches

252 inches + 9 inches = 261 inches

==============

Add those together:

96 inches + 261 inches = 357 inches

Then to convert to feet again, you need to divide by 12 and find the remainder. I prefer to do it with a calculator like this, but you can do it however you prefer:

357 ÷ 12 = 29.75 feet (round down)

12 × 29 = 348 inches in 12 feet

Then find the remainder:

357 - 348 = 9 inches

12 feet 9 inches

It is established that there is always a multiple of 4 between squares of consecutive even numbers.

Take two consecutive even integers into consideration.

If n is an integer, then

The first even number would then be 2n.

Let 2(n+1) be the next consecutive even number.

The following even numbers would follow:

2n, 2(n+1)

Each succeeding even number's square would be:

(2n)² = 2n ×2n = 4n²

[2(n+1)]² = (2n+2)² =(2n+2)(2n+2)

stretching out the brackets

= 4n² +4n +4n+4

[2(n+1)]² = 4n²+8n+4

We would choose values for n and calculate the difference between the squares of each consecutive even number in order to ascertain whether it is always a multiple of 4.

Let n = 1, 2, 3

For n= 1

4n² = 4(1)² = 4×1 = 4

4n²+8n+4 = 4(1)² + 8(1) + 4

= 4+8+4 = 16

The difference between consecutive even numbers' squares is equal to 16/4, or 12.

For n= 2

4n² = 4(2)² = 4×4 = 16

4n²+8n+4 = 4(2)² + 8(2) + 4

= 16+16+4 = 36

36-16 = 20 is the difference between the squares of two consecutive even numbers.

For n= 3

4n² = 4(3)² = 4×9 = 36

4n²+8n+4 = 4(3)² + 8(3) + 4

= 36+24+4 = 64

64-36 = 28 is the difference between the squares of two consecutive even numbers.

12 = 4×3

20 = 4×5

28= 4×7

We can see from the outcomes above that the numbers 12, 20, and 28 are multiples of 4.

As a result, a multiple of four always separates squares of succeeding even integers.

A negative standard score indicates that the original score is lower than the mean.

A standard score, also known as a z-score, is a statistical measure that represents the number of standard deviations an individual score is away from the mean of a distribution. It provides a standardized way to compare and interpret individual scores within a dataset.

When the standard score is negative, it means that the original score is below the mean of the distribution. In other words, the value associated with the score is lower than the average value in the dataset.

For example, if we have a dataset with a mean of 50 and an individual score of 45, we can calculate the standard score (z-score) using the formula:
