The value of x would be 24

Correct Question

For what value of x, is the median class of the following frequency distribution be 30-40?

Class Frequency

0-10 3

10-20 5

20-30 11

30-40 10

40-50 X

50-60 3

60-70 2

Given

• class distribution of an observation

To find

• the value of x so that the median class would be 30 - 40

Solution

we are provided with class interval type of distribution and are asked to find the value of x so that the median class of the given observation shall be on 30 - 40

let us make a cumulative frequency distribution of the given data,

Class Frequency cum. freq

0-10 3. 3

10-20 5 8

20-30 11 19

30-40 10 29

40-50 X. 29+ X

50-60 3 32 + X

60-70 2. 34 + X

now for the median class to be 30 - 40,

(34 + X)/2 = 29 ( making an assumption that the

cumulative frequency would exactly be that of the class )

or, 34+ X = 58

or, X = 24

The value of x would be 24

please gibe the solution anybody

Concept Introduction:-

It is a type of branch where maths are deals with their own properties and also manipulation of numbers.

Given:-

We have been given a case study.

To Find:-

We have to find width.

Solution:-

According to the problem

Width of sidewalk is x m Inner length of pool is (12- 2x) m

Inner beadth of pool (7-2x) m

Area of pool is 36 sq. m

Area of pool =length × breadth

36= (12-2x) ×(7-2x)

36 = 84 - 24x -14x +4x^2

36= 84 -38x +4x^2

4x^2 -38x +48 = 0

2x^2 -19x + 24 = 0

is the required quadratic equation

(ii) solution As we solve the above equation we will find the width of the sidewalk 2(2x^2 - 19x +24) = 0

2x^2 -19- + 24 = 0

2x^2 - 16x -3x +24 = 0

2x(x-8) -3(x-8) =0

(2x-3)(x-8) = 0 X = 3/2 or 8

Width of sidewalk = 8m is not possible

Hence, width of sidewalk is 3/2

Final Answer:-

The final answer is 3/2

Answer:

true

Explanation:

PSU means public sector undertaking. It means that institutions which have 51% share of government and 49% share of private sector.

During PSU all required stakeholders get on boarded and actively participate in project planning and contribute to project's success. Select between true and false.

As we have already studied that the share of government in PSU is 51% and the share of private sector in PSU is 49%. While making any decision in a PSU all required stakeholders get on boarded and actively participate in the planning and contribute to project's success because any plan can make huge profits or huge losses and change ultimately the share of the investors.
