Answer: $10,906
Explanation:
Given that,
Purchased machinery at the beginning of Year 1 = $86,100
machinery has an estimated life of five years,
Estimated residual value = $4,305
Accumulated depreciation = $49,077 at the end of Year 2
Year 3 Depreciation expense:
= ![\frac{Cost\ of\ machinery - Estimated\ residual\ value - Accumulated\ depreciation}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BCost%5C%20of%5C%20machinery%20-%20Estimated%5C%20residual%5C%20value%20-%20Accumulated%5C%20depreciation%7D%7B3%7D)
= ![\frac{86,100 - 4,305 - 49,077}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B86%2C100%20-%204%2C305%20-%2049%2C077%7D%7B3%7D)
= $10,906
Answer:
Sample size = 384.16 ≈ 385
If we increase the order size to 25,000, there will be no change in the sample size as sample size is independent of the number of orders
Explanation:
Data provided in the question:
Number of sales order received per day = 2500
Confidence level = 95%
Certainty factor for 95% certainty = 1.96
Now,
Sample size = ![0.25\times(\frac{\textup{Certainty factor}}{\textup{1 -Desired accuracy}})^2](https://tex.z-dn.net/?f=0.25%5Ctimes%28%5Cfrac%7B%5Ctextup%7BCertainty%20factor%7D%7D%7B%5Ctextup%7B1%20-Desired%20accuracy%7D%7D%29%5E2)
on substituting the respective values, we get
Sample size = ![0.25\times(\frac{\textup{1.96}}{\textup{1 - 0.95}})^2](https://tex.z-dn.net/?f=0.25%5Ctimes%28%5Cfrac%7B%5Ctextup%7B1.96%7D%7D%7B%5Ctextup%7B1%20-%200.95%7D%7D%29%5E2)
or
Sample size = 384.16 ≈ 385
If we increase the order size to 25,000, there will be no change in the sample size as sample size is independent of the number of orders
Each establishment, whether small or big, government-owned or private companies, always have to backup their files in case of emergencies. As you make your backup plan, you must come across these five basic key questions:
1. Are you backing up all your data? You have to sort your files to be backed up because storage can be limited.
2. How often is your data backed up? You must make sure to back up your data on a regular basis, if not day-to-day.
3. Who is responsible for your backups? For big companies, it is too big of a task for one person to shoulder. Usually, this is tackled by a department, usually the I.T. Department.
4. Do your backups actually work? You should test regularly if these back ups actually work by restoring data files every now and then.
5. Do you have right backup checks and balances in place? The I.T Department tackling backup plans is one thing. But there should also be checks and balances so that you have a backup of your backup. It's better to be safe than sorry.
