Answer:
B
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
where F is faces, V is vertices and E is edges
Substitute the values given and solve for F, that is
F + 13 - 26 = 2
F - 13 = 2 ( add 13 to both sides )
F = 15 → B
Step One is to add up all the values
6.5+5+6+5.5+7+4+4.5+5+6+5.5+4+7.5+6+7+8+5+6+6.5+6.5+5 = 116.5
Step Two is to divide the result from step one by 20 (since there are 20 values added up)
116.5/20 = 5.825
The sample mean is 5.825
