The existence of scalars (coefficients) \(c_1,\) \(c_2\), and \(c_3\) that are not all equal to zero will allow us to establish if the vectors 11.3 and 13 and 24 and 7 are linearly independent or not.

Determining whether or not the vectors are linearly independent

c₁ ⎝⎛​−1−13​⎠⎞​ + c₂ ⎝⎛​13−6​⎠⎞​ + c₃ ⎝⎛​24−7​⎠⎞​ = ⎝⎛​0​⎠⎞​

We can rewrite this equation as a system of linear equations:

-c₁ + 13c₂ + 24c₃ = 0

-13c₁ - 6c₂ - 7c₃ = 0

This set of equations can be resolved by creating an augmented matrix and row-reducing it:

| -1 13 24 | | c₁ | | 0 |

| -13 -6 -7 | * | c₂ | = | 0 |

Performing row operations:

R₂ = R₂ + 13R₁

| -1 13 24 | | c₁ | | 0 |

| 0 157 317 | * | c₂ | = | 0 |

R₂ = (1/157)R₂

| -1 13 24 | | c₁ | | 0 |

| 0 1 2 | * | c₂ | = | 0 |

R₁ = R₁ + R₂

| -1 14 26 | | c₁ | | 0 |

| 0 1 2 | * | c₂ | = | 0 |

R₁ = -R₁

| 1 -14 -26 | | c₁ | | 0 |

| 0 1 2 | * | c₂ | = | 0 |

R₁ = R₁ + 14R₂

| 1 0 -12 | | c₁ | | 0 |

| 0 1 2 | * | c₂ | = | 0 |

Now, we have obtained a row-echelon form. The system of equations can be written as:

c₁ - 12c₃ = 0

c₂ + 2c₃ = 0

Since there are just two variables ( c₁ and c₂) and one equation, we can see that this system has an endless number of solutions. Since the equations can be satisfied with any value for  c₃ , we can choose any value for c₁ and c₃ as well.

The vectors ⎝⎛​−1−13​⎠⎞​,⎝⎛​13−6​⎠⎞​, and ⎝⎛​24−7​⎠⎞ are linearly dependent because non-zero values of c₁ c₂ , and c₃ exist that fulfill the equations.

The following system of inequalities is represented by the graph

x+y>3

-x+y< -4

What is inequality?

An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

Consider the  inequalities:

x+y>3-------(1)

-x+y< -4------(2)

Find x and y intercepts of both by considering them as equations by using equal sign in the place of  inequality sign

x+y=3-------(3)

-x+y= -4------(4)

Find x and intercepts of these 2 equations:

we get x intercept when y=0 ( substitute y=0 into the respective equations and find x)

we get y intercept when x=0  ( substitute x=0 into the respective equations and find y)

x intercept of (3) is (3,0)

y intercept of (3) is (0,3)

x intercept of (3) is (4,0)

y intercept of (3) is (0,-4)

The value of the union of sets A and B is, P(A ∪ B) is 0.64.

The union of two sets means the total elements in both the sets combined.

Given: sets P(A) = 0.38, P(B) = 0.83, and  intersection P(A ∩ B) = 0.57

We need to find the union of P(A ∪ B).

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Let us substitute the given values in the formula.

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

=0.38+0.83-0.57

=1.21-0.57

=0.64

Therefore, the value of union of sets P(A ∪ B) is 0.64.

The option that will cause a researcher the most problems when trying to demonstrate statistical significance using a two-tailed independent-measures t-test is d. Low sample means.

When conducting a t-test, the sample means are crucial in determining the difference between groups and assessing statistical significance. A low sample means indicates that the observed differences between the groups are small, making it challenging to detect a significant difference between them. With low sample means, the t-test may lack the power to detect meaningful effects, resulting in a higher probability of failing to reject the null hypothesis even if there is a true difference between the groups.

In contrast, options a and b (high and low variance) primarily affect the precision of the estimates and the confidence interval width, but they do not necessarily impede the ability to detect statistical significance. High variance may require larger sample sizes to achieve statistical significance, while low variance may increase the precision of the estimates.

The core general business principle presented in this topic is "Taking a holistic perspective in decision-making yields the best results."

Among the answer choices provided, the principle that stands out as a core general business principle is "Taking a holistic perspective in decision-making yields the best results." This principle emphasizes the importance of considering all relevant factors, stakeholders, and potential impacts when making business decisions. It recognizes that decisions made in isolation or based solely on a narrow perspective may not yield optimal outcomes.

Taking a holistic perspective means considering the interconnectedness and interdependencies within the business environment, including the social, economic, environmental, and ethical aspects. It involves considering the long-term implications and potential consequences of decisions, as well as the potential impacts on various stakeholders, such as customers, employees, suppliers, and the wider community. By taking a holistic perspective, organizations can make more informed and well-rounded decisions that align with their values, promote sustainability, and contribute to long-term success. It involves analyzing and synthesizing diverse information, seeking multiple perspectives, and understanding the broader context in which decisions are made.

While the other answer choices, such as "Walk the talk," "The customer rules," and "Exchange information for inventory whenever possible," may also reflect important principles in business, they are not as comprehensive or universally applicable as the principle of taking a holistic perspective in decision-making. The latter encompasses a broader approach that considers multiple dimensions of business operations and decision-making, ultimately leading to better overall outcomes.

The approach to probability that assumes that the events are equally likely is d. classical probability.

Classical probability, also known as a priori or theoretical probability, is based on the assumption that all possible outcomes of an experiment or event are equally likely. In this approach, probability is determined by the ratio of favorable outcomes to the total number of equally likely outcomes.

For example, when rolling a fair six-sided die, the classical probability of rolling a specific number, such as a 3, is 1 out of 6 because there is one favorable outcome (rolling a 3) out of six equally likely outcomes (rolling any number from 1 to 6).

Classical probability is often used in situations where the outcomes are known and the sample space is well-defined. However, in practice, events may not always have equally likely outcomes, and other approaches such as empirical or subjective probability may be more appropriate.

The intervals are nested, each subsequent interval is contained within the previous one. Mathematically, this means I₁ ⊇ I₂ ⊇ ... In ⊇ ... . Therefore, we have:

1. I₁ ⊇ I₂ implies [a₁; b₁] ⊇ [a₂; b₂], which means a₁ ≤ a₂ and b₁ ≥ b₂.
2. I₂ ⊇ I₃ implies [a₂; b₂] ⊇ [a₃; b₃], which means a₂ ≤ a₃ and b₂ ≥ b₃.

To show that a1 ≤ a2 ≤ ... ≤ an ≤ ..., we need to use the fact that the sequence of intervals is nested, meaning that each interval is contained within the next one.

First, we know that I1 contains I2, so every point in I2 is also in I1. That means that a1 ≤ a2 and b1 ≥ b2.

Now consider I2 and I3. Again, every point in I3 is also in I2, so a2 ≤ a3 and b2 ≥ b3.

We can continue this process for all the intervals in the sequence, until we reach In. So we have:

a1 ≤ a2 ≤ ... ≤ an-1 ≤ an

and

b1 ≥ b2 ≥ ... ≥ bn-1 ≥ bn

This shows that the endpoints of the intervals are ordered in the same way.

Given that I₁ ⊇ I₂ ⊇ ... In ⊇ ... is a nested sequence of intervals and In = [an; bn], we can show that a₁ ≤ a₂ ≤ ... ≤ an ≤ ... and b₁ ≥ b₂ ≥ ... ≥ bn ≥ ... as follows:

Since the intervals are nested, each subsequent interval is contained within the previous one. Mathematically, this means I₁ ⊇ I₂ ⊇ ... In ⊇ ... . Therefore, we have:

1. I₁ ⊇ I₂ implies [a₁; b₁] ⊇ [a₂; b₂], which means a₁ ≤ a₂ and b₁ ≥ b₂.
2. I₂ ⊇ I₃ implies [a₂; b₂] ⊇ [a₃; b₃], which means a₂ ≤ a₃ and b₂ ≥ b₃.

Continuing this pattern for all intervals in the sequence, we can conclude that a₁ ≤ a₂ ≤ ... ≤ an ≤ ... and b₁ ≥ b₂ ≥ ... ≥ bn ≥ ... .

The original short-run supply curve shifts left, causing the market price to decrease to P2 and the quantity to decrease to Q2.

As a result, some firms exit the market, causing the short-run supply to shift back to the right and the market to return to equilibrium at a lower quantity, Q3, and the same price, P2.

When demand decreases, the original short-run supply curve shifts leftward as firms reduce production to meet the lower demand. This causes the market price to decrease to P2 and the quantity to decrease to Q2.

At this lower price, some firms may exit the market if they are unable to cover their costs, causing the short-run supply curve to shift back to the right.

As a result, the market quantity decreases further to Q3, and the market returns to equilibrium at the same price, P2. In the long run, the supply curve may shift further to accommodate the lower demand, resulting in a new equilibrium price and quantity.
