• How can we test the origin of life hypothesis “the Spontaneous Abiotic Origin”?

Compare the elasticity of a monopolistic competitor’s demand with that of a pure competitor and a pure monopolist. Assuming identical long-run costs, compare the prices and outputs that would result in the long run under pure competition and under monopolistic competition. Contrast the two market structures in terms of productive and allocative efficiency. Explain: “Monopolistically competitive industries are populated by too many firms, each of which produces too little.”

Labor Variances Cinturon Corporation produces high-quality leather belts. The company's plant in Boise uses a standard costing system and has set the following standards for materials and labor: Leather (3 strips @ $4) $12.00 Direct labor (0.75 hr. @ $12) 9.00 Total prime cost $21.00 During the first month of the year, the Boise plant produced 92,000 belts. Actual leather purchased was 287,500 strips at $3.90 per strip. There were no beginning or ending inventories of leather. Actual direct labor was 78,600 hours at $12.50 per hour.

Required: 1. Break down the total variance for labor into a rate variance and an efficiency variance using the columnar and formula approaches.

Rate variance $ 39,300

Unfavorable Efficiency variance $ 46,000 Unfavorable ??????

Total variance $ -276,900 Unfavorable ????

2. CONCEPTUAL CONNECTION As part of the investigation of the unfavorable variances, the plant manager interviews the production manager. The production manager complains strongly about the quality of the leather strips. He indicates that the strips are of lower quality than usual and that workers have to be more careful to avoid a belt with cracks and more time is required. Also, even with extra care, many belts have to be discarded and new ones produced to replace the rejects. This replacement work has also produced some overtime demands. What corrective action should the plant manager take? Return to suppliers that provide the quality corresponding to the price standard. Employ more skilled labor at a cost lesser than the savings made by buying cheap material and improve the product quality. There is no need to change anything. The sales are not affected by this low quality of raw material.

Java.

Write 3 methods named addArrays, subArrays, and mulArrays each.

addArrays gets two matrices(int [][] array1, int [][] array2) as parameters and add them and returns the result (matrix).

subArrays gets two matrices(int [][] array1, int [][] array2) as parameters and subtract array2 from array1 and returns the result (matrix).

mulArrays gets two matrices(int [][] array3, int [][] array4) as parameters, multiplying them and returning the result(matrix).

A solution contains 1.20×10-2 M zinc acetate and 8.67×10-3 M copper(II) nitrate.

its a discussion responding we are responding to. Does your organization have a formal mentoring program and/or leadership development program, explain Do you currently have a mentor or serve as a mentor, explain Discuss some goals that you can set for yourself to further develop as a leader.

Help responding in 150 or more words given details.

My organization has a mentoring program that partners up individuals wanting to move up in the company. We use Individual Development plans in order to guide training and development. This is a tool assists employees in career path and personal development. IDP’s are essential to being able to assign learning activities to specific competencies. We assign actionable tasks and track their progress in reasonable time frames. We also offer internships to college students in which they spend six weeks in leadership roles and provide them with the training and knowledge of how to become effective leaders. I am currently serving as a mentor to a new employee that has less experience. I allow individuals that I am mentoring to tell me what their expectations from me are. I also set up times for scheduled meetings to set goals, give and receive feedback, and find out what they may need from me. Goals that I could use in order to further develop myself as a leader by strategic thinking. “Improve my ability to see the big picture and take a longer range, broader business perspective. Learn to step back from the day-to-day tactical details of my business and focus on the “why”, not just the “what” and “how” (McCarthy, 2010). Looking at the big picture would guide me in becoming a more effective leader by being able to see what the importance of things is instead of just doing. Another goal would be to support and manage change in the organization because this would the transition of things easier during role outs of new programs or practices. There are many things one could do to become a better leader, but at the end of the day being sincere and honest is the best practice.

Wage and Tax Statement Data on Employer FICA Tax

Ehrlich Co. began business on January 2. Salaries were paid to employees on the last day of each month, and social security tax, Medicare tax, and federal income tax were withheld in the required amounts. An employee who is hired in the middle of the month receives half the monthly salary for that month. All required payroll tax reports were filed, and the correct amount of payroll taxes was remitted by the company for the calendar year. Early in the following year, before the Wage and Tax Statements (Form W-2) could be prepared for distribution to employees and for filing with the Social Security Administration, the employees' earnings records were inadvertently destroyed.

None of the employees resigned or were discharged during the year, and there were no changes in salary rates. The social security tax was withheld at the rate of 6.0% and Medicare tax at the rate of 1.5% on salary. Data on dates of employment, salary rates, and employees' income taxes withheld, which are summarized as follows, were obtained from personnel records and payroll records:

Required:

1. Calculate the amounts to be reported on each employee's Wage and Tax Statement (Form W-2). Enter amounts to the nearest cent if required. Enter all amounts as positive numbers.

2. Calculate the following employer payroll taxes for the year: (a) social security; (b) Medicare; (c) state unemployment compensation at 5.4% on the first $10,000 of each employee's earnings; (d) federal unemployment compensation at 0.8% on the first $10,000 of each employee's earnings; (e) total. Round your answers to two decimal places.
