Random sample - choosing a sample so that every member has an equal chance of being chosen (this is the absolute definition of random sampling)

Sample - a portion of a large group is termed as a sample.

Biased sample - choosing a sample from people who are under 15 years old (biased sampling states that all the members of a group are not included in survey)

Estimating from a sample - using the responses of a small group to make conclusions about the large group.(estimation means roughly judging something based on some sample )

Answer:

The linear equations for the given Rectangle are

$y = 4x +4$
$y = 6x - 6$

Step-by-step explanation:

Given:

area given by 'y'

For figure 1,

$Length = x +1\\Breadth = 4\\\textrm{Area of Rectangle} = Length\times Breadth\\y= (x+1)\times 4\\y= 4x + 4$

For figure 2,

$Length = 2x -2\\Breadth = 3\\\textrm{Area of Rectangle} = Length\times Breadth\\y= (2x-2)\times 3\\y= 6x - 6$

Now we will plot the these two line on DESMOS so, we will have the intersection of these two line.

So, the intersection points are (5,24) that is x coordinate '5' and y coordinate '24'.

∴ $x=5\ and\ y=24$

For figure 1,

∴ $Length =x+1\\=5+1\\=6\ unit\\Area=4x + 4\\=4\times5 +4\\=24\textrm{ square units}$

For figure 2,

∴ $Length =2x-2\\=2\times5-2\\=8\ unit\\Area=6x - 6\\=6\times5 -6\\=24\textrm{ square units}$

Which are the solutions of x^2=-11x+4

jeyben [28]

Simplifying X2 + -4 = 0 Reorder the terms: -4 + X2 = 0 Solving -4 + X2 = 0 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + X2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + X2 = 0 + 4 X2 = 0 + 4 Combine like terms: 0 + 4 = 4 X2 = 4 Simplifying X2 = 4 Take the square root of each side: X = {-2, 2}
