A grid map marks the plot of Harold’s garden in meters. The coordinates of the quadrilateral-shaped property are G(–8, 3), A(4,

8), R(10, 0), and D(–2, –5). He wants to build a short fence around the garden. The perimeter of his garden is meters.

To calculate for the perimeter of the garden, we have to solve for the measures of each of the sides of the four-sided polygon. That is calculated by getting the distances between consecutive points. 

The equation for the distance is,
         
                            d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

Distance from G and A,
                            d = sqrt ((4 - -8)² + (8 - 3)²)
                                 d = 13
Distance from A to R,
                           d = sqrt ((10 - 4)² + (0 - 8)²)
                                  d = 10
Distance from R to D,
                            d = sqrt ((-2 - 10)² + (-5 - 0)²
                                  d = 13
Distance from D to G,
                            d = sqrt ((-8 --2)² + (-5 -3)²)
                                  d = 10

Summing up all the four calculated distances will give us an answer of 46. Thus, the perimeter of the garden is 46 units.

The pth percentile is a value such that approximately a. p percent of the observations are less than the value and (100 - p) per
kogti [31]

Answer:

p percent of the observations are less than the value and (100 - p) percent are more than this value.

Step-by-step explanation:

Given : The pth percentile is a value such that approximately

Solution :

Definition : A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls

So, The pth percentile means p percentage of observations in a group of observations falls bellow the value

So, (100-p) percentage of observations in a group of observations falls above the value

So, Option a is true

Hence p percent of the observations are less than the value and (100 - p) percent are more than this value.
