If the median of the following data is 33 then, find the value of m: Class Frequency 0 - 15 1715 - 30 3530 - 45 4045 - 60 1860 - 75 m75 - 90 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.

The quadratic equation in terms of x is 4x²-38x+48 = 0 and the width of the sidewalk is 1.5 m.

Given,

The outer edges of the swimming pool are 7m and 12 m.

The width of the sidewalk is x m.

The area of the pool = 36 sq. m

To Find,

The quadratic equation in terms of x, and the width of the sidewalk.

Solution,

Since the width of the sidewalk is x m.

So the dimensions of the pool will be (7-2x) and (12-2x).

Now,

Area of the pool = 36 sq. m

(7-2x)(12-2x) = 36

84-14x-24x+4x² = 36

4x²-38x+48 = 0

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

x = 8, 1.5

The value of x can't be 8 as it will make the dimensions of the pool negative

So, the value of x is 1.5 m.

Hence, the quadratic equation in terms of x is 4x²-38x+48 = 0 and the width of the sidewalk is 1.5 m.

Answer:

The quadratic equation in 'x' is 2x² -19x +24 = 0

Width of the sidewalk = 1.5m

Explanation:

Given,

Area of the pool = 36sq.m.

width of the sidewalk = 'x'm

Length of the pool including the sidewalk = 7m

Breadth of the pool including the sidewalk = 12m

Required to find,

Quadratic equation in terms of 'x'

Width of the sidewalk

Formula to be used

Area of the rectangle = length x breadth

Length of the pool = 7 -2x

Breadth of the pool = 12 -2x

Area of the pool = (7-2x)(12-2x)

(7-2x)(12-2x) = 36

84 - 14x -24x +4x² = 36

4x² - 38x + 48 = 0

2x² - 19x + 24 = 0

Hence,

The quadratic equation in 'x' is  2x² - 19x + 24 = 0

To find 'x'

To solve the quadratic equation by splitting the middle term, we need to find two numbers such that their sum = -19 and product = 48

Two such numbers are = -16 and -3

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

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

2x -3 = 0 or x = 8

x =[tex]\frac{3}{2}[/tex]  = 1.5 or x = 8

x = 8, is not possible because the length of the pool including the sidewalk is 7m.

So x = 1.5m

∴ Width of the sidewalk = 1.5m

take an =

get n = 12

then find S12 to get it as 540

Answer: Sum of first 12 2 digit numbers which are multiple of 6 is 540.

Step-by-step explanation:

Given series : 12, 18, 24, 30, 36, .....

This is an Arithmetic Progression.

[tex]a_{1} = 12[/tex]

common difference = 6

∴ [tex]S_{12} = \frac{n}{2} (2*a_{1} + (n - 1) * d)[/tex]

         = [tex]\frac{12}{2} (2*12 + (12 - 1) * 6)[/tex]

         = 540
