The best sampling method that Is most appropriate for the town planner is called Stratified Sampling.
<h3>What is the Sampling Method used?</h3>
The best sampling method that I would recommend for the town planner is called Stratified Sampling.
The reason for using stratified sampling is because it is a method of sampling that involves dividing a population into smaller groups–called strata and in this case, the rows of houses can be used as a strata.

Answer:
y=-1
Step-by-step explanation:
- Since we see an overlap, the line must cross through the original image.
- We can solve the equation of the line of reflection by realizing there is no slope because the reflection is parallel to the x-axis.
The circle theoremss that cyclic quadrilaterals can be related to include:
- Every corner of the quadrilateral touches the circumference of the circle.
- The ratio between the diagonals and the sides can be defined.
- The product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.
<h3>What is a cyclic quadrilateral?</h3>
It should be noted that cyclic quadrilateral simply means a quadrilateral that's drawn inside a circle.
In this case, every corner of the quadrilateral must touch the circumference of the circle.
Also, the product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.

Answer:
Step-by-step explanation:
The square root is possible only if y≤0
if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0
if y≤0 can be rewritten as:
3(-27x^2y^7)^1/2
or if we want simplify the expression:
^1/2
we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive
