The mean squared error minimization smoothing constant's value can be found using a nonlinear optimization process.

Although the linear programming model is effective in many nonlinear optimization circumstances, it is insufficient to accurately model some issues. An illustration would be the isoperimetric problem, which asks you to identify the closed plane curve with the maximum area and a minimization given length. Pappus of Alexandria had access to the solution but not the proof. 340 CE.

The Swiss mathematician Johann Bernoulli challenged himself in 1696 to find the curve that minimizes the time it takes an object to slide, using minimization only the force of gravity, between two nonvertical points. This challenge marked the beginning of the branch of mathematics known as the nonlinear optimization calculus of variations. Along with Johann Bernoulli, the correct answers were also provided by his brother Jakob Bernoulli, the German Gottfried Wilhelm Leibniz, and the Englishman Isaac Newton. (The solution is the brachistochrone.) Many nonlinear algorithms, in particular, heavily rely on Newton's method of solving the problem.

You are choosing between these four investments and you want to be 95% certain that you do not lose more than 8.00% on your inv

borishaifa [10]

Answer: B. Corporate Bonds and T-Bills

Explanation:

As you want to be 95% certain, this would require a 95% confidence interval.

With the given returns and standard deviations, the range of returns expected will be computed by;

Upper limit = Return + 2*SD

Lower limit Return - 2*SD

Stocks

Upper Limit = 18.37% + 2 (38.79%)

= 96.0%

Lower Limit = 18.37% - 2 (38.79%)

= -59.2%

S&P 500

Upper Limit = 11.84% + 2(20.01%)

= 51.9%

Lower Limit = 11.84% - 2(20.01%)

= -28.2%

Corporate Bonds

Upper Limit = 6.47% + 2(6.98%)

= 20.4%

Lower Limit = 6.47% - 2(6.98%)

= -7.5%

T-Bills

Upper Limit = 3.46% + 2(3.14%)

= 9.7%

Lower Limit = 3.46% - 2(3.14%)

= -2.8%

The lower limit show the lowest return achievable given a 95% confidence level.

Only Corporate Bonds and T-Bills will give a minimum that is above 8% so they should be chosen.

Pacanowsky’s cultural approach to organizations offers metaphors for empowered groups in a company acting like jazz musicians, e

lesantik [10]

Pacanowsky used metaphor to describe the cultural approach where he described the organisation as “a cluster of peasant villages” or as “a large improvisational jazz group” and described its workers as “factions in Colonial America.”

Explanation:

By definition, the cultural approach to deal with authoritative communication investigates an association by thinking about antiques, qualities, and presumptions that happen as a result of the connections of hierarchical individuals. Relics are the standards, gauges, and customs you see in hierarchical correspondence.

Pacanowsky applied Geertz's information on organisations. They said culture is networks of essentials, frameworks of shared significance. A social exhibition is the means by which we uncover our way of life to ourselves as well as other people. To examine societies, you should utilize ethnography a method for finding who individuals are inside a culture.

Complete question:

Oriole Company has a balance in its Accounts Payable control account of $8,170 on January 1, 2020. The subsidiary ledger contains three accounts: Hale Company, balance $2,550; Janish Company, balance $1,580; and Valdez Company. During January, the following payable-related transactions occurred.

Purchases Payments Returns

Hale Company $6,529 $5,972 $ -0-

Janish Company 5,066 2,087 2,215

Valdez Company 6,647 6,790 -0-

What is the January 1 balance in the Freeze Company subsidiary account?

What is the January 31 balance in the control account?

Balances in the subsidiary accounts Bixler $ Cuddyer $ Freeze$

Which January transaction would not be recorded in a special journal?

Solution:

What is the January 1 balance in the Freeze Company subsidiary account?

8,170 - 2,550 - 1,580 = 4040

What is the January 31 balance in the control account?

8,170 + 6,529 + 5,066 + 6,647 - 5,972 - 2,087 - 6,790 - 2,215 = 1,995

Compute the balances in the subsidiary accounts at the end of the month.

Hale 2,550 + 6,529 - 5,972 = 3,107

Janish 1,580 + 5,066 - 2,087 - 2,215 = 2,344

Valdez 4040 + 6,647 - 6,790 = 3,897

Which January transaction would not be recorded in a special journal?

Identify the detective control below.

Darina [25.2K]

Answer:

Reconciling the bank statement to the cash control account.

Explanation:

The reason is that the detective approach is the one which helps in identification of the errors in recording the facts and figure in a control system is the detective control. In this case, bank reconciliation helps in accessing the errors and entries that are not recorded in the books of accounts hence it is a detective control.

Over the past 4 years, Cardi, age 28, has contributed a total of $20,000 to a Roth IRA. The current balance is $25,000. She was

Juliette [100K]

Answer:

Explanation:

According to the scenario, computation of the given data are as follow:-

Contributed amount = $20,000

Distribution amount = $15,000

As we know,

Taxable amount = Distribution amount - contribution amount

= $15,000 - $20,000

= - $5,000

The contribution amount is $20,000 more than the distribution amount $15,000. So distribution amount is not taxable.

She included $0 amount in her gross income this year.
