The Poster Dimensions of rectangle will be:

W = 18 inches

Y = 36 inches

Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (square centimeters, square inches, square feet, etc.). The area of ​​a rectangle is the number of unit squares that fit in the rectangle. Examples of rectangles are flat surfaces such as laptop monitors, chalkboards, and painting canvases. You can use the rectangle area formula to find the space occupied by these objects.

Now,

Let's say the printable area of ​​a rectangular poster is 512 square inches

"x". " and "y" - the dimensions of the printed area of ​​the poster

A(p) = printed area of ​​the poster = x × y

512 = x × y ⇒ y = 512/x

Therefore, The total area of ​​the poster is:

A( t) = ( y + 4 ) ×  ( x + 2 )

⇒ A(t) = yx +2y +4x + 8 and y = 512/x

Total Area of x or Total poster area as x function:

   A(x) =( 512/x)*x + 2* (512/x) + 4*x + 8

   A(x) = 512 + 1024/x + 4 *x + 8

⇒ A(x) = 520 + 1024/x + 4*x

Differentiating both sides of the equation gives:

     A´(x) = - 1024/x² + 4

     A´(x) = 0

⇒ - 1024 /x² = -4

⇒  4*x² = 1024

⇒ x² = 1024/4

⇒ x² = 256

or, x = 16 inches

and y = 512/x

⇒ y = 512/16

⇒ y = 32 inches

So x is found, the y dimension of the print area, Than n is the dimension of the poster:

Therefore,

w = x + 2 ⇒ w = 16 + 2 w = 18 in

And,

Y = y + 4 ⇒ Y = 32 + 4 Y = 36 in

As per the concept of survey, Nonresponse is the type of bias that happens when individuals with certain characteristics are less likely to respond to surveys than others.

What is the working process of survey?

In general terms, survey refers a set of questions people are asked to gather information or find out their opinions, or the information gathered by asking many people the same questions.

Here we need to find the type of bias occurs when individuals with certain characteristics are less likely to respond to surveys than others.

As we know that, when respondents to a survey question or the entire survey are unable or unwilling to respond, this is known as nonresponse bias. Individuals have many excuses for not responding and a cause of error must be systematic in order to be categorized as biased.

Here the distinction between respondents and non-respondents frequently plays a role in explaining why there was no response.

Therefore,  Non-response bias, also known as participation bias, is sometimes the result of shoddy survey design and poor questionnaire targeting.

The required pounds of Bolivian coffee and Colombian coffee are 2500 and 1500 respectively.

A equation is supposed to be linear equation in two factors in the event that it is written as ax + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are direct conditions in two factors.

Let x be the pound of Bolivian coffee and y is that of Colombian coffee.

Bolivian coffee sells for $4.59 per pound, and Colombian coffee sells for $5.95 per pound and whole mixture sells for $5.10.

So,  4.59x + 5.95y = 5.10(4000)

4.59x + 5.95y = 20400--------------------(1)

and x + y = 4000-----------------------------(2)

Step-by-step explanation:

Work done by the person for the displacement of 100m along +x-axis with constant velocity and mass of 10kg is equal to 0Joule.

As given in the question,

Mass of a person 'm' = 10kg

Displacement of the person while walking along +x axis 'd'= 100m

Constant velocity = 2m/s

Let 'w' be the work done by the person

Work = Force × Displacement

Force = mass × acceleration

Acceleration = (final velocity - initial velocity)/ total time taken

Here, Constant velocity ⇒final velocity - initial velocity = 2- 2

                                                                                      = 0m/s

⇒Acceleration = 0m/s²

⇒Force = 10 × 0

             = 0Kgm/s²

⇒Work done = 0 × 100

                     = 0 Joule

Therefore, work done by the person for the given displacement, velocity, and mass is equal to zero Joule.
