Which combination of changes would increase the glomerular filtration rate (gfr the most?

saul85 [17]

Answer:

The answer is below.

Explanation:

The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

a) Given that n = 100, μ = 2000, σ = 18

For x < 1995 millimeters:

$z=\frac{x-\mu}{\sigma/\sqrt{n} }=\frac{1995-2000}{18/\sqrt{100} } =-2.78$

From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027

b) P(z > z*) = 10% = 0.1

P(z < z*) = 1 - 0.1 = 0.9

z* = 1.28

$z*=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\1.28=\frac{x-2000}{18/\sqrt{100} }\\\\x-2000 =-2.304\\\\x=2002.3\ ml\\\\$

From the normal distribution table, P(z < z

Mays Corp. reported free cash flows for 2018 of $491 million and investment in operating capital of $321 million. Mays Corp. inc

Anon25 [30]

Answer: $975 million

Explanation:

Given the above details, we can solve for Earnings Before Tax and Interest with the following formula,

Operating Cash Flow = EBIT – Taxes on EBIT + Depreciation

Making EBIT the subject would turn it to be,

EBIT = Operating Cash Flow + Taxes on EBIT - Depreciation

We have all of the above except the EBIT and Operating Cash Flow.

Luckily we can solve for the Operating Cash Flow with the details given using,

Operating cash flow = Free Cash Flow + Investment in operating capital

Therefore,

= $491 million + $321 million

= $812 million

Operating cash flow is $812 million

Plugging it into the original formula we have,

EBIT = Operating Cash Flow + Taxes on EBIT - Depreciation

EBIT = $812 million + $309 million - $146 million

EBIT = $975 million

Earnings before Taxes and Interest is $975 million.

Babcock Company purchased a piece of machinery for $36,000 on January 1, 2019, and has been depreciating the machine using the s

pogonyaev

Answer:

Requirement 1:

Dr Accumulated Depreciation $9,600

Cr Retained Earnings Account $9,600

Requirement 2:

Dr Depreciation Expense $6,000

Cr Accumulated Depreciation $6,000

Explanation:

Year Remaining Life of machine Depreciation fraction

1 5 5/15

2 4 4/15

3 3 3/15

4 2 2/15

5 1 1/15

Total 15

Now here, the depreciation formula is as under:

Depreciation expense = (Cost - Salvage Value) * Fraction value

Year 2019:

The sum of years digit fraction would be 5/15 and the cost of the machinery is $36,000. So

Depreciation Expense = ($36,000 - 0) * 5/15 = $12,000

Year 2020:

The sum of years digit fraction would be 5/15 and the cost of the machinery is $36,000. So

Depreciation Expense = ($36,000 - 0) * 4/15 = $9,600

Year 2021:

Now in this year the there is change in estimate and a switch in the use of the depreciation method, which is now straight line method. The change in estimate only includes the useful life of the asset which is 6 years from the date of purchase.

So for straight-line depreciation:

Depreciation Expense = (Cost - Salvage Value) / Useful Life

By simply putting values, we have:

Depreciation Expense = $36,000 / 6 years = $6,000 per year

So this means, according to change in accounting policy, the excess depreciation charged must be eliminated from the previous years. The depreciation charge for the previous 2 years must be $12,000 and the excess depreciation charge is calculated as under:

Carrying value of the asset = $21,600 - $12,000 = $9,600

Requirement 1:

The double entry according to the US GAAP, for the excess depreciation charge in the previous years would be the waiving off of retained earnings with the excess depreciation amount calculated above.

Dr Accumulated Depreciation $9,600

Cr Retained Earnings Account $9,600

Requirement 2:

The depreciation expense for the year 2021, would be recorded as under:

Dr Depreciation Expense $6,000

Cr Accumulated Depreciation $6,000
