5.The employees of Xitrex, Inc., are paid each Friday. The company’s fiscal year-end is June 30, which falls on a Wednesday for the current year. Salaries and wages are earned evenly throughout the five-day work week, and $13,000 will be paid on Friday, July 2.
Required:
1. Prepare an adjusting entry to record the accrued salaries and wages as of June 30, a reversing entry on July 1, and an entry to record the payment of salaries and wages on July 2.
2. Prepare journal entries to record the accrued salaries and wages as of June 30 and the payment of salaries and wages on July 2 assuming a reversing entry is not recorded.

Answers

The entry to record the payment of salaries and wages on July 2 is a debit to Salaries and Wages Payable and a credit to Cash.

1. The adjusting entry on June 30 is necessary to recognize the expense for salaries and wages earned but not yet paid. It increases the Salaries and Wages Expense account and creates a liability in the Salaries and Wages Payable account.

The reversing entry on July 1 is made to simplify the subsequent accounting process and ensure accurate financial reporting. On July 2, when the payment is made, the Salaries and Wages Payable account is reduced, and Cash is decreased by the same amount.

2. Without a reversing entry, the journal entry on June 30 still recognizes the expense for salaries and wages earned but unpaid. The Salaries and Wages Expense account is debited, reflecting the expense, and the Salaries and Wages Payable account is credited, indicating the liability.

On July 2, when the payment is made, the Salaries and Wages Payable account is reduced, and Cash is decreased by the same amount. The absence of a reversing entry means that the Salaries and Wages Expense account will continue to reflect the total expense accrued throughout the fiscal year, rather than resetting to zero at the beginning of the new period.

Answer:

C) Line A does not intersect Line B.

Step-by-step explanation:

Line A passes through (6 ,-30) & (-2 , 10)

Line B passes through (-4 , 28) & (2 , -2)

Find the slopes for each line. To find the slope, use the slope formula:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Line 1:

Let:

[tex](x_1 , y_1) = (6 , -30) \\(x_2 , y_2) = (-2 , 10)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{10 - (-30)}{-2 - 6} = \frac{10 + 30}{-8} = \frac{40}{-8} = \frac{-5}{1}[/tex]

Line 2:

Let:

[tex](x_1 , y_1) = (2 , -2)\\(x_2 , y_2) = (-4 , 28)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{28 - (-2)}{-4 - (2)} = \frac{28 + 2}{-4 - 2} = \frac{30}{-6} = \frac{-5}{1}[/tex]

The two lines share the same slope, therefore, they are parallel to each other. This means that they do not intersect at any given point.

When we use this, the father is 57 times taller than him inside the photo, so since the daughter (in photo) is 2 cm, her height should be 2*57 cm.

Consider the following IVP: y' = ty + t², 0≤ t ≤ 2, y(0) = 1 The exact solution of this IVP is y(t) = y = -t² − 2(t+1) + 3et a. Use Euler's method with step size h = 0.1 to approximate y(1) (you can use Matlab and set a table of values)

Answers

The value of y(1) is found to be approximately 2.6742 based on the approximate values obtained using Euler's method.

First, we divide the interval [0, 1] into 10 subintervals (h = 0.1), resulting in 11 points including the initial point.

Using the Euler's method, we start with the initial condition y(0) = 1 and iterate the following formula for each step:

y_(i+1) = y_i + h * (t_i * y_i + t_i^2)

Calculating the values iteratively, we obtain a table of values for t and y as follows:

t | y

0.0 | 1.0000

0.1 | 1.1000

0.2 | 1.2110

0.3 | 1.3343

0.4 | 1.4708

0.5 | 1.6228

0.6 | 1.7920

0.7 | 1.9802

0.8 | 2.1892

0.9 | 2.4202

1.0 | 2.6742

Therefore, using Euler's method with a step size of h = 0.1, the approximate value of y(1) is 2.6742.

Euler's method is a numerical method used to approximate the solution of ordinary differential equations (ODEs). It uses small steps to approximate the derivative and iteratively updates the solution at each step. In this case, we applied Euler's method with a step size of h = 0.1 to approximate the solution y(1) for the given initial value problem. By calculating the values iteratively using the formula y_(i+1) = y_i + h * (t_i * y_i + t_i^2), we obtained a table of values that approximate the solution. The value of y(1) is found to be approximately 2.6742 based on the approximate values obtained using Euler's method.

1 A very small takeaway cafe with 2 baristas has customers arriving at it as a Poisson process of rate 60 per hour. It takes each customer 3 min- utes, on average, to be served, and the service times are exponentially distributed. Interarrival times and service times are all independent of each other. There is room for at most 5 customers in the cafe, includ- ing those in service. Whenever the cafe is full (i.e. has 5 customers in it) arriving customers don't go in and are turned away. Customers leave the cafe immediately upon getting their coffee. Let N(t) be the number of customers in the cafe at time t, including any in service. N(t) is a birth and death process with state-space S = {0, 1, 2, 3, 4, 5}. (a) Draw the transition diagram and give the transition rates, An and Un, for the process N(t). (b) If there is one customer already in the cafe, what is the probability that the current customer gets her coffee before another customer joins the queue?

Answers

The probability that the current customer gets their coffee before another customer joins the queue, given that there is one customer already in the cafe, is 0.5.

(a) The transition diagram for the birth and death process N(t) with state-space S = {0, 1, 2, 3, 4, 5} is as follows:

rust

Copy code

 ----> 0 ----> 1 ----> 2 ----> 3 ----> 4 ----> 5 ---->

  Un=60   An=0   Un=60   An=0   Un=60   An=0   Un=0

In this diagram, the transitions from state i to i+1 represent the arrival of a customer, denoted by An, with a rate of 60 per hour. The transitions from state i to i-1 represent the departure of a customer, denoted by Un, with a rate of 60 per hour when the cafe is not empty (i.e., i > 0). The transition from state 5 to state 4 has a rate of 0 since no customer can enter the cafe when it is full.

(b) If there is one customer already in the cafe (state 1), the probability that the current customer gets their coffee before another customer joins the queue can be calculated using the concept of first-passage time. The probability can be obtained by calculating the probability that the process reaches state 0 before reaching state 2.

Let P(i) denote the probability of reaching state 0 before reaching state 2, starting from state i. We have:

P(1) = An / (An + Un)

In this case, An = 60 and Un = 60, so:

P(1) = 60 / (60 + 60) = 0.5

To test Hou= 103 versus Hy #103 a simple random sample of size n = 35 is obtained. Does the population have to be normally distributed to test this hypothesis? Why? O A. Yes, because the sample is random
OB. No, because n >=30. OC. No, because the test is two-tailed OD. Yes, because n>=30.

Answers

No, the population does not have to be normally distributed to test the hypothesis in this scenario. The correct answer is OB. No, because n >= 30.

In hypothesis testing, the assumption of normality is primarily related to the sampling distribution of the test statistic rather than the population distribution itself.

The Central Limit Theorem states that for a sufficiently large sample size (typically n >= 30), the sampling distribution of the sample mean or proportion tends to follow a normal distribution, regardless of the shape of the population distribution.

In this case, the sample size is given as n = 35, which satisfies the condition of having a sufficiently large sample size (n >= 30).

Therefore, we can rely on the Central Limit Theorem, which implies that the sampling distribution of the test statistic (such as the sample mean) will be approximately normal, even if the population distribution is not.

The choice of a two-tailed test or the fact that the sample is random does not determine whether the population needs to be normally distributed.

It is the sample size that plays a key role in allowing us to make inferences about the population based on the Central Limit Theorem.

Hence, the correct answer is OB. No, because n >= 30. The assumption of normality is not required in this scenario due to the sufficiently large sample size.

Hydrostatic force =

Answers

The pool's hydrostatic force is 1,500 pounds at the shallow end, 4,500 pounds at the deep end, 1,500 pounds on each side from shallow to deep, and 0 pounds at the bottom.

(a) To compute the pressure the water exerts at that depth and multiply it by the shallow end's surface area, we must first measure the hydrostatic force on the shallow end. The equation P = gh, pressure is P, is the fluid's density, acceleration from gravity is g, the depth is h, determines the pressure that a fluid exerts at a given depth.

In this case, the depth of the shallow end is 3 ft. The weight density of water is given as 62.5 lb/ft³.

Plugging in these values, we have,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (3 ft)

P = 1,500 lb/ft².

To find the hydrostatic force, we multiply this pressure by the surface area of the shallow end, which is the width times the length,

Hydrostatic force = 1,500 lb/ft² * (20 ft * 40 ft)

Hydrostatic force = 1,500 lb. Therefore, the hydrostatic force on the shallow end is 1,500 lb.

(b) Using the same method as in part (a), we find that the pressure exerted by the water at the depth of the deep end, which is 9 ft, is ,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (9 ft)

P = 4,500 lb/ft².

Multiplying this pressure by the surface area of the deep end (20 ft * 40 ft), we get the hydrostatic force on the deep end,

Hydrostatic force = 4,500 lb/ft² * (20 ft * 40 ft)

Hydrostatic force = 4,500 lb.

Therefore, the hydrostatic force on the deep end is 4,500 lb.

(c) The depth of the side is varying linearly from 3 ft to 9 ft. Taking the average depth, we have (3 ft + 9 ft) / 2 = 6 ft.

Using the formula,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (6 ft),

We find that the pressure is 3,000 lb/ft².

Multiplying this pressure by the surface area of the side (20 ft * 6 ft), we get the hydrostatic force,

Hydrostatic force = 3,000 lb/ft² * (20 ft * 6 ft)

Hydrostatic force = 1,500 lb.

(d) Since the bottom of the pool is horizontal, the depth remains constant throughout, which is 3 ft. Plugging this value into the formul,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (3 ft),

p =  1,500 lb/ft², we find that the pressure is 1,500 lb/ft². However, since the bottom is horizontal, the surface area facing upward cancels out the surface area facing downward, resulting in a net force of 0 lb.

Therefore, the hydrostatic force on the bottom of the pool is 0 lb.

For a particular route, for example, the trucker is paid $X for transporting the load within 48 hours from pick-up to delivery, and is paid three times that amount if it delivers within 18 hours from pick-up to delivery. To accomplish the faster delivery time, the driver must drive essentially nonstop for 18 hours. The company ascertains over time that the accident rate for serious injury accidents for its drivers over all is three times higher on the faster deliveries compared to the accident rate with the slower more flexible deliveries. Discuss what ethical issues and legal risks the company faces from this two-tiered payment system.Company A and Company B are unable to pay their obligations as they come due and will file bankruptcy cases.
