Abin contains red balls and purple balls. a ball is selected at random and then placed back in the bin. the results are recorded after 10 trials, 50 trials, and 200 trials. the results are recorded in the table.

outcome| number of trials
|
red |
purple |

based on the table, how many times can you expect that a purple ball will be selected in 400 tries?

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.
