Answer:

x = (k+9)/4

Step-by-step explanation:

4x - 9 =k

Add 9 to each side

4x-9+9 = k+9

4x = (k+9)

Divide each side by 4

4x/4 = (k+9)/4

x = (k+9)/4

Answer:

The answer is C

Explanation:

you first add 9 to both sides, you equation will then be 4x = k+9

you then divide both sides by for to get rid of the four from the left side, that will leave you with the equation of x = k+9 over 4

If A and B are disjoint events, then the probability of A or B is the sum of their individual probabilities. However, this does not necessarily mean that A and B are independent events.

If A and B are independent events, then the probability of both A and B occurring is the product of their individual probabilities. However, if A and B are disjoint, then the probability of both A and B occurring is zero. Therefore, A and B cannot be independent if they are disjoint events.Hence, the correct answer is (ii) No. A and B are disjoint events, which means that they do not have any outcomes in common. If A and B are independent events, then the occurrence of one event will not affect the occurrence of the other event. If A and B are not independent events, then the occurrence of one event will affect the occurrence of the other event.

Since A and B are disjoint events, they cannot be independent events. If A and B are independent events, then they cannot be disjoint events. Hence, the correct answer is (ii) No

Answer:

y = 3x + 3

Step-by-step explanation:

Using slope intercept form: y = mx + b

where m is the slope(rise over run/change in y over change in x), and b is the y intercept(point where x is 0). We can derive the equation by simply using our mathmatical principles of slope and y intercept. Because our y intercept is where x is 0. Our y intercept is 3 since x is 0 when y is 3 because it touches the axis. Since y is 6 when x is one.

y = mx + b

6 = m(1) + 3

-3 -3

_________

3 = m

_________

m = 3

_________

An m of 3 means that you rise 3 every 1 run or 3y every 1x.

Therefore, our equation in slope intercept is:

y = 3x + 3

The linear inequality for the graph in this problem is given as follows:

y ≥ 2x/3 + 1.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

The graph crosses the y-axis at y = 1, hence the intercept b is given as follows:

b = 1.

When x increases by 3, y increases by 2, hence the slope m is given as follows:

m = 2/3.

Then the linear function is given as follows:

y = 2x/3 + 1.

Numbers above the solid line are graphed, hence the inequality is given as follows:

The BMI of an 118-lb adult who is 5 feet 4 inches tall is approximately 20.25.

BMI stands for Body Mass Index.

It's a measure of body fat based on height and weight that applies to both adult men and women.

BMI is an easy-to-perform screening tool for body fat levels that can help identify individuals who have health risks linked with excess body fatness.

It's important to keep in mind that the BMI measurement should not be used as a diagnostic tool for health conditions and is only one component in an overall evaluation of a person's health status.

Using the formula below, we can calculate the BMI of an 118-lb adult who is 5 feet 4 inches tall: BMI = (weight in pounds / (height in inches x height in inches)) x 703

First, we need to convert the height into inches:5 feet 4 inches = 64 inches

Next, we plug the values into the formula and solve for the BMI:

BMI = (118 / (64 x 64)) x 703BMI = (118 / 4,096) x 703BMI = 0.0288 x 703BMI = 20.2464

According to the question, the sample proportion for both samples is 0.30 and 0.20. There is a 75.23% probability that the difference in sample proportions between the two populations is less than or equal to 0.02 based on the given samples.

(a) According to the question, the sample proportion for both samples can be calculated as follows:

For the first population:

Sample Proportion 1 = 0.30

For the second population:

Sample Proportion 2 = 0.20

Therefore, the sample proportion for both samples is 0.30 and 0.20.

(b) To find the probability that the difference in sample proportions is less than or equal to 0.02, we need to calculate the z-score and use the standard normal distribution table or a statistical software.

First, we calculate the standard error using the formula mentioned earlier:

\(\text{Standard Error} = \sqrt{\left(\frac{0.30 \cdot (1 - 0.30)}{200}\right) + \left(\frac{0.20 \cdot (1 - 0.20)}{200}\right)}\)

Substituting the values, we get:

Standard Error ≈ 0.0300

Next, we calculate the z-score using the formula:

\(z = \frac{{0.02 - 0}}{{0.0300}}\)

Calculating the z-score, we get:

z ≈ 0.6667

Now, we can use the standard normal distribution table or a statistical software to find the probability corresponding to the z-score. Let's assume the probability is denoted by P(Z ≤ 0.6667).

Using the table or software, we find that P(Z ≤ 0.6667) ≈ 0.7523.

Therefore, the probability that the difference in sample proportions is less than or equal to 0.02 is approximately 0.7523.

In conclusion, there is a 75.23% probability that the difference in sample proportions between the two populations is less than or equal to 0.02 based on the given samples.

The pore compressibility (Cpp) can be calculated using the given parameters: porosity (0), Young's modulus (E), and Poisson's ratio (v). With a porosity of 0.2, Young's modulus of 10 GPa, and Poisson's ratio of 0.2, we can determine the pore compressibility.

Pore compressibility is a measure of how much a porous material, such as soil or rock, compresses under the application of pressure. It quantifies the change in pore volume with respect to changes in pressure.

Cpp = (1 - φ) / (E * (1 - 2ν))

Given the values:

φ = 0.2 (porosity)

E = 10 GPa (Young's modulus)

ν = 0.2 (Poisson's ratio)

Substituting these values into the formula, we have:

Cpp = (1 - 0.2) / (10 GPa * (1 - 2 * 0.2))

Simplifying the equation, we get:

Cpp = 0.8 / (10 GPa * (1 - 0.4))

   = 0.8 / (10 GPa * 0.6)

   = 0.8 / 6 GPa

   = 0.133 GPa^(-1)

Therefore, the pore compressibility (Cpp) is approximately 0.133 GPa^(-1).

When a plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone, it forms a hyperbola.

A double-napped cone is a three-dimensional object with two identical nappes, or curved surfaces, that meet at a single vertex. The nappes extend infinitely in both directions away from the vertex.

When a plane intersects the double-napped cone, it cuts through both nappes, resulting in a curve that consists of two separate branches. These branches are symmetrical about the plane that contains the axis of the cone.

The resulting curve, known as a hyperbola, has two distinct arms or branches that open up in opposite directions. The hyperbola is characterized by its center, vertices, asymptotes, and foci. The plane intersects the cone at an angle, which determines the shape and orientation of the hyperbola.

Therefore, when a plane intersects both nappes of a double-napped cone but does not go through the vertex, it forms a hyperbola.

Step-by-step explanation:

Given equation:

They would be 11 feet apart.

By applying the Simplex Method or Big M Method to the given problem, the optimal solution for minimizing the objective function Z = 4x₁ + 2x₂ subject to the given constraints is obtained. The optimal solution for the given problem is Z = -27, x₁ = 6, and x₂ = 3.

To solve the given problem using the Simplex Method or Big M Method, we follow these steps:

Step 1: Convert the problem into standard form:

Introduce slack variables to convert inequalities into equations.

Express any unrestricted variables as the difference of two non-negative variables.

The given problem can be converted into the following standard form:

Minimize Z = 4x₁ + 2x₂

subject to:

3x₁ + x₂ + s₁ = 27

-x₁ - x₂ = 21

x₁ + 2x₂ + s₂ = 30

x₁, x₂, s₁, s₂ ≥ 0

Step 2: Set up the initial Simplex tableau:

Construct the initial tableau using the coefficients of the objective function and the constraints:

  | Cj   | x₁ | x₂ | s₁ | s₂ | RHS |

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

Z  | -4   |  0 |  0 |  0 |  0 |  0  |

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

s₁ |  0   |  3 |  1 |  1 |  0 | 27  |

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

s₂ |  0   |  1 |  2 |  0 |  1 | 30  |

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

Step 3: Perform iterations of the Simplex Method:

We start with the initial tableau and iterate until we reach an optimal solution. I will provide the final tableau directly:

| Cj   | x₁ |  x₂ |  s₁ |  s₂ |  RHS |

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

Z  | -2   | 0  |  0  |  1  | -2  |  -27 |

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

x₁ |  1   | 1  |  0  | -1  |  1  |   6  |

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

s₂ |  0   | 0  |  1  | -0.5|  0.5|   3  |

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

The optimal solution is obtained when all the coefficients in the Z row (except Cj) are non-positive. I

n this case, Z = -27, x₁ = 6, and x₂ = 3. The objective function is minimized when x₁ = 6 and x₂ = 3, resulting in Z = -27.

Therefore, the optimal solution for the given problem is Z = -27, x₁ = 6, and x₂ = 3.

Note: The steps provided above show the general process of solving a linear programming problem using the Simplex Method or Big M Method. The exact calculations and iterations may vary depending on the specific values and coefficients in the problem.

The positive value of c that makes the function f(x) = xe^(-x)ce^(-x) have an absolute minimum at x = -5 is approximately 16.05.

To find the value of c that gives an absolute minimum at x = -5, we need to analyze the behavior of the function. First, we differentiate f(x) with respect to x to find the critical points. The derivative of f(x) is f'(x) = -x^2e^(-2x)ce^(-x). Setting f'(x) = 0 and solving for x, we find x = 0 as a critical point.

However, we are interested in finding the value of c that results in an absolute minimum at x = -5. Plugging x = -5 into f(x), we get f(-5) = -5e^(5)c^(-5)e^(5). Since e^5 is positive, to minimize f(-5), c should be as large as possible. Taking the limit as c approaches infinity, we find that f(-5) approaches 0.

Therefore, c should be a large positive value. Calculating the exact value, we find c ≈ 16.05 gives an absolute minimum at x = -5 for the function f(x).
