the matrix form of project management structure is a good choice when resource usage needs to be optimized by having individuals work on multiple projects while still performing functional duties. T/F

Answers

The given statement "the matrix form of project management structure is a good choice when resource usage needs to be optimized by having individuals work on multiple projects while still performing functional duties " is true because Matrix management is a type of organizational structure

Where employees are assigned to both functional and project teams, enabling team members to work across different projects while continuing to perform their functional duties. This approach allows organizations to optimize resource utilization by allocating employees where they are needed most while still maintaining the integrity and

efficiency of functional teams. Matrix management also provides a better opportunity for professional development, as employees can work on projects outside their core competency area, creating a more diversified portfolio of skills. The structure has its advantages and disadvantages and requires a skilled leader to be successful in executing it effectively.

If a random sample of 2 customers is selected, find the probability that the average waiting time is more than 6.0 min

Answers

The probability that the average waiting time of a random sample of 2 customers is more than 6.0 minutes is approximately 0.0043, or 0.43%.

To calculate the probability that the average waiting time of a random sample of 2 customers is more than 6.0 minutes,

Given:

Mean (μ) = 3.7 min

Standard deviation (σ) = 1.4 min

The average waiting time of a sample of 2 customers is the sum of the waiting times divided by 2. Let's define X as the average waiting time.

The mean of the sum is equal to the sum of the individual means, and the variance of the sum is equal to the sum of the individual variances. Since we are dealing with the average, we need to divide the variance by the sample size.

Mean of the sum = 2 * 3.7 = 7.4 min

Variance of the sum = 2 * ([tex]1.4^2[/tex]) = 3.92 [tex]min^2[/tex]

Variance of the average = (3.92) / 2 = 1.96 [tex]min^2[/tex]

Now, we can standardize the average waiting time using the z-score formula:

z = (X - μ) / (σ / √n)

In this case, X = 6.0 min, μ = 3.7 min, σ = 1.4 min, and n = 2.

z = (6.0 - 3.7) / (1.4 / √2)

z = 2.3 / (1.4 / √2)

z ≈ 2.602

Next, we need to find the probability that the standardized variable z is greater than 2.602.

Using a standard normal distribution table or calculator, we find that P(Z > 2.602) = 0.0043.

Suppose your phone is initially at rest on a table. You then pick up your phone and place it on the ground. If the system is the Phone Only, which of the following statement is true during this process? Explain your choice. 1.The Earth did work on the system 2.The system has gravitational potential energy and gravitational potential energy changed 3.Both 1 and 2 are true

Answers

Both 1 and 2 are true; the Earth does work on the system and its gravitational potential energy changes, option 3 is correct.

When you pick up the phone and place it on the ground, the Earth exerts a force on the phone, doing work on it. This work is the transfer of energy from the Earth to the phone. As a result, the phone gains gravitational potential energy as its position changes relative to the ground. Initially at rest on the table, the phone possesses some gravitational potential energy.

However, as it moves downward, its height decreases, causing a decrease in gravitational potential energy. Therefore, both statements 1 and 2 hold true for the system of the phone only, option 3 correct.

4. nonhoning canine - While the nonhoning canine is a feature of hominins, it is not related to bipedalism.

Answers

Short ilium and s-shaped curve of the spine are the features that are associated with bipedalism as seen in humans. Therefore, options 1 and 2 are correct.

The hominin spine is curved to attain balance in an upright position, which is one trait, and the small ilium of the pelvis is vital in providing stability for bipedal walking. About four million years ago, apes started the evolution of human bipedalism. According to certain theories, bipedalism improved the energy efficiency of movement and played a significant role in the evolution of bipedal locomotion. When walking, humans use less energy than quadrupeds, but not when running. Running by a human is 75% less effective than walking. According to a 1980 study, traveling on a quadruped or a biped costs the same, but walking on a biped is substantially more efficient than walking on a quadruped.

Second tier distributions are: Amounts distributed to charitable

Answers

The second-tier distributions are the amounts distributed to charitable organizations. A private foundation that has been set up is required to distribute its funds to various charitable organizations.

The foundation can choose to donate money to a public charity, but it may also choose to donate to a non-charitable organization, which is classified as a second-tier distribution. A private foundation is required to distribute five percent of its net investment assets each year to charitable organizations. To satisfy this requirement, private foundations make grants or gifts to nonprofit organizations.

A grant can be used for research, construction, or other types of projects, while a gift is made without any expectation of a specific outcome. Second-tier distributions are considered risky because they can be made to non-charitable organizations. When a private foundation makes a second-tier distribution, the organization must be aware that the recipient organization is not a charity and that there is a possibility that the funds may be used for non-charitable purposes.

if the payoffs from strategy Y are always greater than the payoffs from strategy X, it can be concluded that strategy Y strictly dominates strategy X.

In game theory, the concept of dominance is used to compare strategies in terms of their outcomes. When one strategy consistently provides better outcomes than another strategy, it is said to dominate the other strategy.

if  the payoffs from strategy Y are always greater than strategy X, it means that strategy Y consistently yields higher rewards or benefits compared to strategy X, regardless of the actions chosen by other players in the game. In this scenario, strategy Y is clearly the superior choice, as it provides more favorable outcomes across all possible scenarios.

When one strategy strictly dominates another, it means that the dominating strategy is preferred regardless of the actions taken by other players. This implies that strategy Y is the best option for the decision-maker, as it always leads to greater payoffs than strategy X.

She has just informed your parents that she wants to go to Hampton University, which will cost $17,000 per year for four years (cost assumed to come at the end of each year). Anticipating Linda's ambitions, your parents started investing $2,000 per year five years ago and will continue to do so for five more years. How much more will your parents have to invest each year for the next five years to have the necessary funds for Linda's education?

Let x = age in years of a rural Quebec woman at the time of her first marriage. In the year 1941, the population variance of x was approximately 2 = 5.1. Suppose a recent study of age at first marriage for a random sample of 31 women in rural Quebec gave a sample variance s2 = 2.5. Use a 5% level of significance to test the claim that the current variance is less than 5.1.(a) What is the level of significance?(b) Find the value of the chi-square statistic for the sample.
