Please help me with this math homework answer

1.25

Step-by-step explanation:

To get the mean, you need to first add up all the numbers.

1/4+3/4+5/4+7/4+ 3/4+11/4=30/4.

30÷4=7.5

Next, you need to divide the sum by the number of numbers.

7.5÷6=1.35

So, the mean is 1.25.

is it 35

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.
