Answer:
An 18 sided shape.
Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon
Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
