In a certain school,260 students were present on monday,270 on tuesday,280 on wednesday, and 250 on thursday find the average number of students present on those four days

The average number of students present are 265

Step-by-step explanation:

Given the number of students present on monday were 260, the number of students present on tuesday were 270 , the number of students present on wednesday were 280 , the number of students present on thursday are 250.

Now the numbers are 260, 270, 280, 250

We should basically find the average of these four observations

We know that the

sum of the observations is 260+270+280+250=1060

number of observations are 4

Average=     =265

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.
