A population has mean 27 and standard deviation 10 . What is the data value that has a z-score of -2 ?

Answers

Answer 1

Answer:

Explanation:

The z-score, or a standardized test score equals:

z = (x - μ) / σ)

Thus substitute -2 into z, 27 into μ, and 10 into σ

-2 = [tex]\frac{x-27}{10}[/tex]

Thus solve for x:

-2(10) = x - 27

x = -2(10) + 27

x = -20 + 27 = 7

Answer:

Checkers is a versatile game that delights both

kids and adults.

Explanation:

Because it is an opinion that checkers is delighting and subjective language basically means opinionated.

Debugging a program entails identifying and correcting its faults.

What is debugging?
In computer programming & engineering, debugging is a multistep process that entails locating a problem, tracking down the source of the issue and either fixing the problem directly or finding a workaround. Testing the fix or workaround to make sure it functions is the last stage in the debugging process. When a developer is able to find and reproduce a code error inside a computer programme, the debugging process in software development gets started. The software testing process, as well as the full software development lifecycle, includes debugging.

Exercise 11-25 (Algo) Change in principle; change in depreciation methods [LO11-2, 11-6] For financial reporting, Clinton Poultry Farms has used the declining-balance method of depreciation for conveyor equipment acquired at the beginning of 2018 for $2,750,000. Its useful life was estimated to be five years, with a $155,000 residual value. At the beginning of 2021, Clinton decides to change to the straight-line method. The effect of this change on depreciation for each year is as follows: ($ in thousands) Year Straight Line Declining Balance Difference 2018 $ 519 $ 1,100 $ 581 2019 519 660 141 2020 519 396 (123 ) $ 1,557 $ 2,156 $ 599 Required: 2. Prepare any 2021 journal entry related to the change.

Answers

The journal entry that's related to the change is the depreciation expense of $116333.

What is a journal entry?

The act of logging any transaction, whether or not it is an economic one, is known as a journal entry. Transactions are recorded in an accounting journal that shows the debit and credit balances of a company. The journal entry may contain many recordings, each of which is either a debit or a credit.

Depreciation or bond amortization are examples of recurring items that can be recorded in journal entries. Accounts payable normally has its own subledger that indirectly impacts the general ledger, and journal entries are frequently filed using a different module in accounting software. As a result, general ledger account balances are changed directly by journal entries.

The declining-balance method of depreciation was applied by Clinton Poultry Farms on conveyor equipment purchased at the beginning of 2018. In this case, the journal entry is attached.
