• It is rigidly defined 
• It is based on all salues of the dala 
• It should not be affected by the extreme alues of the data 
• It should have the sampling stability
• It should be capable of further statistical analysis

For better comparison if C.S.D. is expressed in percentages it is called Co-efficient of coefficient of variation ie., co-efficient variation [c.v] = \(\frac {σ}{X}\)100.

If the data is divided into various parts, the dividing points are called partition Values. The partition values are Median, Quartiles, Deciles and Percentiles.

The partition values are Median, Quartiles, Deciles and Percentiles.

Registration of a joint stock company is compulsory. 

Explanation: 

According to the Indian Companies Act 1956, every Indian company has to be registered with the Registrar of Companies.

(b) Beauty Parlour 

(A) Government company,
(B) Holding company and
(C) subsidiary company.

The Perimeter of Auditorium = (21 + 2b) units = (2 × 80 + 2 × 30)

= 160 + 60

= 220 metres

Auditorium walls have to be decorated with colour buntings = 220 × 4 = 880 metres The cost of the buntings used to decorate the auditorium = 880 × 15 = 13,220

The cost of 1 metre of bunting = Rs 15

Correct option is (C) Company

Securities and Exchange Board of India.

Correct option is (A) SEBI

when a coin is tossed the sample space S ={Head, Tail}; n(s) = 2; n(H) = 1;

P(A) + P(A²) = 1 or P(A²) = 1- P(A)

P(A²) = 1-1/4 ; P(A²) = 3/4.

The probability of occurrence of one event under the condition that another event has already occurred is known as conditional probability.

The probability that B will occur under the condition that Alias already occurred is denoted by P(B/A). 

P(B/A) = Total number of favourable cases of B/Total number of favourable cases of A)

Similarly, The probability that A will occur under the condition that B has already occurred is denoted by P(A/B).

Statement: Let A and B be two independent events with respective probabilities P(A) and P(B). Then, the probability of simultaneous occurrence of A and B is

P(A ∩ B)= P(A) × P(B).

Objects that emit light are known as sources of light. 

Ex : Sun, candle, tube light.

(i) Fundamental principle for two events states that “If an event can occur in m different ways, following which another even occur in n different ways, then the total number of occurrence of the events in the given order is m x n. 

(ii) Fundamental principle for three events states that, “If an event can occur in m different ways, following which second event occurs in n different ways, following third event can occur in p different ways, then the total number of occurrence of the events in the given order is

Sources like sun, stars emit light on their own. Such type of sources are called natural sources of light.

Sources that release light artificially are called man made sources of light or artificial sources of light.

Natural sources of light : Sources which release ’light energy on their own are called natural sources of light.

Angle of reflection (r) : The angle made by the reflected ray with the normal is called the angle of reflection (r).

A piece of glass or any other transparent material with curved sides is called a lens.

Lens which is thin in the centre and thick at the edges is called concave lens.

There are two laws of reflection :

1. Angle of incidence is equal to Angle of reflection. 

2. The incident ray, reflected ray and normal to the surface are present in the same plane. Incident and reflected rays are on either side of normal.

Concave mirror : Concave mirrors is a spherical mirror with reflecting surface bent inward.

Characteristics of image by plane mirror: 

1. Object distance is equal to image distance. 

2. Size of the object is equal to size of the image. 

3. The image formed is always virtual and erect.

4. Laterally inverted image is formed, (left and right alternates)

Lens which is thick in center and thin at the edges is called convex lens.

Convex mirror : Convex mirrors is a spherical mirror with reflecting surface bent outward.

A convex mirror always forms virtual, erect, smaller image irrespective of the position of the object.

The image which we get on screen is called real image

The image which cannot get it on screen is called virtual image.

All the plane mirrors form virtual and erect image.

The correct comments are:

(i) In saponification reactions, heat is evolved.

(ii) Saponification reaction is not a neutralization reaction.

(iii) Soap is nothing but a salt of fatty acids.

Red litmus paper turn blue and blue litmus paper remains colourless, as soap solution is basic in nature.

Olive oil (A) and sodium hydroxide forms soap (B).
