The Median of the data 78,56,22,34,45,54,39,68,54,84

54

Step-by-step explanation:

The Median of the data 78,56,22,34,45,54,39,68,54,84

Median of a data is the value at the middle after rearrangement

Rearrange in ascending 0rder

22, 34, 39, 45), 54, 54, (56, 68, 78, 84

The two numbers at the middle are 54 and 54

Median = 54 + 54/2

Median = 108/2

Median = 54

Hence the median of the data is 54

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
