And Joule and the calorie are units of measurement for the amount of work and energy. Joule is part of a single system of measurement SI, the calorie is a non-si unit. Sometimes calculations are required to translate joules into calories.

Writing research projects in school is a critical step in the formation of student skills in independent work with information. In a school project the student can reflect the structure and essence of a job well done. Prizes at conferences, requiring the provision of school projects that give various bonuses when you enroll in College.

Right cone is a body, which is obtained by rotating a right triangle around one of the legs. This leg is the height of the cone H, the other side is the radius of its base R, the hypotenuse is equal to the multiple forming of a cone L. Method of finding the radius of the cone depends on the initial data of the problem.

The economic effect of the call expressed in monetary units, the difference between income received from certain activities within a certain period of time and the cost of its implementation over the same period.

All points of a circle projected on a plane should be parallel to this plane. Since all planes in an isometric projection are inclined, the circle takes the form of an ellipse. To simplify the work of the ellipses in an isometric projection are replaced with ovals.

Charged bodies can affect each other without contact via an electric field. Field that is generated by the electrical stationary particles is called electrostatic.

Axonometric projection is used to convey the drawing is a representation of the shape of the object from different sides. In this view of the subject from different angles projected onto the plane of the cube. The slope of the planes in axonometric projection of a circle gives the shape of an ellipse. Because of the difficulty of constructing ellipses in practice they are replaced by ovals.

The dodecahedron is a proper polyhedron consisting of equal pentagons. Due to the fact that the dodecahedron has 12 faces, its model can be successfully used as a Desk calendar. For this we only need to glue the dodecahedron of suitable material and unusual souvenir is ready. And you can make a dodecahedron is simply out of colored paper, he and without a calendar will look very impressive.

To assess the production specialization of individual enterprises apply the calculations of certain indicators. Among others, calculate the coefficient of specialization. This indicator characterizes the degree of specialization production enterprise.

For analyzing any data set is often used the absolute deviation. It allows you to quickly and effectively show the difference between different elements, between the initial result and the achieved results.

Discounting is a definition value of future cash flows in real time. The coefficient of discounting shows how much cash we get given the time factor and risks. With it, we convert future value the value at the moment.

For analysis of the major funds on the balance sheet are calculated indicators of efficiency of their use. One of them is the shift factor. This indicator shows the number of shifts worked each piece of equipment for a certain period of time.

Elasticity in Economics is called the percentage change of one parameter against another. The coefficient of elasticity is calculated, for example, to characterize changes in the relationship between the demand for goods and income of the consumer, between the demand for and price of the goods.

A complete technical drawing contains at least three projections. However, the ability to imagine the object on the two projections is required as a technologist and a skilled worker. Therefore, in the examination tickets in technical universities and colleges continuously meet the challenges of building a third type, with two specified. To successfully complete this task, you need to know conventions used in technical drawing.

On financial stability, we can conclude, knowing about the extent of its dependence on borrowed funds, the ability to maneuver their own capital. This information is important for the owners of the company, its investors, and counterparties (buyers of finished products and raw material suppliers).

To know the average score usually needs graduates, as they sometimes are interested in when applying for a job. Its calculation is made according to the method of determining the arithmetic mean of all the ratings (we are talking only about those estimates that are in the diploma).

The average value in the statistics is called the generalized indicator that characterizes the level of change homogeneous units together. In any case, between characterized by symptoms must be present relationship.

The cost of goods is the sum of all expenses of the enterprise connected with its production. This value is the minimum price at which costs are fully covered by income. So to find the cost of production is an important, purposeful action, the first step on the road to profits.

Every accountant faces every day with the decision of those or other problems, because of them is the whole accounting. For example, did the goods to your warehouse. In addition, you will be received, you must calculate the amount of input VAT and the calculation of taxes is to take it into account. So for any aspiring accountant is very important to know the theoretical and practical foundations of accounting.

Curve Lorenz , in economic theory is called a curve showing the distribution of income and measures the degree of inequality in the distribution of national income. There are different ways of measuring income inequality. One of them is the Gini coefficient, characterizing the location of the Lorenz curve. The Gini coefficient shows the extent of the variation (inequality) of income distribution.

Prediction of growth of population is a very important tool for long-term planning of economic and social development of society. This calculation of the value of its labor and volume needs.

The objective of any statistical calculations is to build a probabilistic model of a random event. This allows you to collect and analyze data on specific observations or experiments. A confidence interval is used when a small sample that allows to determine with a high degree of reliability.

Essays like essay, free usually has an arrangement and a small size. Although the task would be easy, but for some reason, scares the students and catches them by surprise.

Net exports is one of the main indicators of macroeconomics. It can be positive or negative. Definition of this parameter only at first glance simple. In fact, the most accurate calculation is possible only when considering multiple influencing factors.

Economic and social planning of any country is based on the projected change in the population. Citizens are at the same time its labor and consumer resource for the evaluation of which is necessary to determine the rate of natural increase.

Natural decline is the loss, reduction in the quantity of goods while maintaining its quality. It can be caused by shrinkage, leakage, evaporation processes, that is, natural changes in the biological or physico-chemical properties of inventory items. The natural decline leads to deficiency, which is necessary to prepare the appropriate documents and reflected in accounting and tax accounting.

Demand is the utility level of a product to consumers. To see how he would react to a price change or the average income level, it is necessary to determine the elasticity of demand. This index is calculated as a ratio and expressed in percentage.

Indexes are of great importance in economic theory, they function as indicators and indexes of dynamics of various processes. In particular, the index of physical volume shows how many times the increased or decreased volume of trade turnover in the same period of time compared with baseline.

Profit from realization of products is one of the main indicators of the financial results of operations of the company. The results of the company usually summarized on a quarterly basis after the preparation of the financial statements. However, profit from the implementation it is possible to calculate monthly.

The Mann-Whitney test used to evaluate differences in the severity of the sign for two unrelated or independent samples. These selections can vary according to a number of subjects. The Mann-Whitney test is particularly reliable when the number of subjects not exceeding 20 persons.
