weighted average = $108,530 - $85,697 = $22,833

specific identification = $108,530 - $85,245 = $23,285

Explanation:

the inventory records are missing, so I looked for a similar question:

first we should calculate COGS:

under FIFO

March 15 sales = (660 x $60) + (55 x $57) = $42,735

September 10 sales = (275 x $57) + (110 x $45) + (160 x $65) + (185 x $61) = $42,310

total = $85,045

under LIFO

March 15 sales = (110 x $45) + (330 x $57) + (275 x $60) = $40,260

September 10 sales = (570 x $61) + (160 x $65) = $45,170

total = $85,430

under weighted average

March 15 sales = 715 x ($108,530 / 1,830) = $42,404

September 10 sales = 730 x ( / 1,830) = $43,293

(660 x $60) + (230 x $57) + (110 x $45) + (110 x $65) + (335 x $61) = $85,245

First in, first out (FIFO) is an uncomplicated approach of inventory valuation based on the presumption that commodities acquired or created first are sold first. This implies that older inventory is distributed to customers before fresh inventory, in theory. Even if there have been recent changes in expenses, the cost of goods sold (COGS) of the oldest inventory is used to assess the value of ending inventory. More current merchandise often costs more than older stuff due to inflation. Since the lower valued items are sold first when using the FIFO approach, the ending inventory usually has a higher value.

Incident Response is the set of activities taken to plan for, detect, and correct the impact of an incident on information assets.

Incident response (IR) is a set of information security policies and procedures that can be used to identify, contain, and remediate cyberattacks. The goal of incident response is to help organizations detect and contain attacks quickly, minimize damage, and prevent future attacks of the same type.

An Incident Response Plan (IRP) is a set of documented procedures detailing the steps that should be taken at each stage of incident response. This should include guidelines on roles and responsibilities, a communication plan, and standardized response procedures.

Within an IRP, it is important to use clear language and define ambiguous terms. Groups of terms that are often confused are events, alerts, and incidents. If we plan uses these conditions, it may be helpful to restrict their use as follows:

Event - Change in system settings, status, or communication. Examples of this are server requests, authorization updates, or data deletions.

Alerts - Notifications triggered by events. Alerts can alert you to suspicious or normal events that require your attention. For example, using unused ports and running out of memory resources.

The attacker that can use intentional RF interference to flood the RF spectrum with enough interference to prevent a device from effectively communicating with the AP is a Jammer.

What is RF interference?

The most effective way of reducing interference from radio frequency (RF) is to use shielding and filtering. Shielding involves surrounding the area in question with a barrier that blocks the RF waves. This can be done with metal plates, conductive fabrics, or other materials. Filtering involves the use of special filters to limit the amount of RF waves that can pass through. These filters can be placed in line with cables or in the form of antennas. Other methods of reducing RF interference include using directional antennas, adjusting the power settings of the device, and using low-loss cabling. Finally, ensuring that all devices are properly grounded can help to reduce the effects of RF interference.

The rate at which energy is rejected by heat transfer to the cold reservoir, is; 0.55 MW

b) The comparison shows that there is an increased efficiency and reduced heat rejection in the reversible power cycle working between the given two reservoirs

We are given;

The temperature of the hot reservoir; T_h  = 600 K

The temperature of the cold reservoir; T_c  = 300 K

The power output; W' = 0.45 MW

The heat input from the hot reservoir; Q'_in  = 1 MW

a) The thermal efficiency of the actual cycle is gotten from the formula;

η_actual = W'/Q'_in

Where;

W' is the work done

Q'_in is  the heat supplied

Thus;

η_actual = 0.45/1

η_actual  = 0.45 = 45%

The rate at which energy is rejected by heat transfer to the cold reservoir, Q_c , is given by the formula;

Q_c = Q'_in - W'

Thus;

Q_c = 1 - 0.45 = 0.55 MW

B) For a reversible power cycle, the maximum cycle efficiency is gotten from the formula;

η_maximum = (T_h - T_c)/(T_h)

Thus;

η_maximum = (600 - 300)/600
