Yogita Ingle 6 years, 4 months ago

An important method of organization of data is to distribute data into different classes on the basis of their characteristics. This process is known as Classification of Data. Classification is the grouping of related facts into classes or groups. Unorganized or shapeless data can neither be easily compared nor interpreted. The technique of arranging the data in different homogeneous groups is known as Classification.
According to Horace Secrist, "Classification is the process of arranging data into sequence and groups according to their common characteristics or separating them into different but related parts.

Daily life in an ancient Mesopotamian city depended on a person’s status and occupation. Almost all societies and cultures are hierarchical with rulers at the top and laborers at the bottom. By the time people began living in cities, circa 4000 B.C., societies had different classes and a variety of occupations.

<div>

Consider 100 g of glass

So, mass of SiO2=100-(12.9+2.2+3.8+0.4)=80. 7 g
mass of B2O3= 12.9 g
Mass of 1 mole of SiO2 i.e. molar mass of SiO2=28+16×2=60 g
Now, 60 g of SiO2 contains 1 mol of Si atom
So, 80.7 g of SiO2 contains 160×80.7=1.345 mol of Si
Similarly, Molar mass of B2O3=2×10+3×16=68 g
Now, 68 g of B2O3 contains 2 mol of B atom
So, 12.9 g of B2O3 contains 268×12.9=0.379 mol of B

An account balance is the difference between the debits and credits posted to the account during the current accounting period plus the beginning balance. Not all accounts maintain balances from one accounting period to the next. Temporary accounts are closed at the end of each accounting cycle to permanent accounts, which carry the balances on to the next accounting period.

Igneous rocks are those rocks which have been formed by the cooling and solidification of molten natural matter of the earth.
The igneous rocks are formed when magma cools and turns into solid forms. The process of the cooling and solidification can happen in the earth's crust as well as on the surface.

What is a PPC

Posted by Anjali Jha 6 years, 4 months ago

CBSE > Class 11 > अर्थशास्त्र

1 answers

Yogita Ingle 6 years, 4 months ago

In business, the Production Possibility Curve (PPC) is applied to evaluate the performance of a manufacturing system when two commodities are manufactured together. The management utilizes this diagram to plan the perfect proportion of goods to produce to reduce the wastage and cost while maximizing profits.

The diagram or graph explains how many units of goods a company can produce if all the resources are utilized productively. Therefore, a single commodity’s maximum manufacturing probability is arranged on the X-axis and other on the Y-axis. Here, the curve is represented to show the number of products that can be created with limited resources and pausing the use of technology in between.

In the graph, the line sloping down also depicts the tradeoff between producing commodity A and commodity B. When a firm diverts its resources to produce commodity B, the production of commodity A will reduce.

A point above the curve indicates unattainable with the available resources. A point below the curve means the production is not utilizing 100 per cent of the ‘business’s resources.

Step 1 : Divide (43)₁₀ successively by 2 until the quotient is 0:
43/2 = 21, remainder is 1
21/2 = 10, remainder is 1
10/2 = 5, remainder is 0
5/2 = 2, remainder is 1
2/2 = 1, remainder is 0
1/2 = 0, remainder is 1
Step 2 : Read from the bottom (MSB) to top (LSB) as 101011. This is the binary equivalent of decimal number 43

explain the law of variable proportion with proper schedule and diagram

Posted by Devender Pal 6 years, 4 months ago

CBSE > Class 11 > Economics

1 answers

Sia ? 6 years, 4 months ago

Law of variable proportion states the impact of change in units of a variable factor on the physical output. When more and more units of a variable factor are combined with a fixed factor then total product increases at increasing rate in the beginning, then increases at decreasing rate and finally it starts falling.
Phase I : TP increases at an increasing rate.
Phase II : TP increases at diminishing rate.
Phase III : TP falls.
Behaviour of MP
Phase I: MP increases and becomes maximum.
Phase II: MP decreases and becomes zero.
Phase III: MP becomes negative

<th scope="col">Machine</th> <th scope="col">Unit of Labour</th> <th scope="col">TPP (Unit)</th> <th scope="col">MPP(Unit)</th>

1	1	3	3
1	2	7	4

1	5	19	3
1	6	21	2
1	7	22	1
1	8	22	0
1	9	21	-1

First Phase : TPP increases with increasing rate upto A point. MPP also increase and becomes maximum at point C.
Second Phase : TPP increases with diminishing rate and it is maximum at point B. MPP start to decline and becomes zero at D point.
Third Phase : TPP starts to decline and MPP becomes negative.

Important instruction for giving the answer of above question.
Do not use diagram for the explanation of this question if it is instructed to use schedule and do not use schedule if the explanation of this question asked with the help of diagram.
Do not explain the behaviour of marginal product with the help of schedule and diagram. If there is instruction to explain only the behaviour of total product.
Do not explain the behaviour of total product with help of schedule and diagram if there is instruction to explain only the behaviour of marginal product.
