Answer:
Nathan's because his sample was more random
Step-by-step explanation:
Nathan's survey could be described as a Systematic random sampling technique whereby every 5th observation taken as a sample from the population. With these technique we have a more random observation than with.
Answer:
Step-by-step explanation:
1] the minimum number of arcs in any strongly connected digraph with n vertices is 'n' . the graph look like a cycle
the graph is in the attached file
in a directed cycle we have strongly connected graph since we can reach any vertax from any vertax, it has minimum arc which is 'n'
since if we use less than n vertax then the given graph has atmost one tree which is not strongly connected graph.
2] the maximum distance between two vertax is 5 which from veratx 1 to vertax 6 distance is 5
1----->2------->3--------->4------->5-------->6
if we use cycle of n node then the maximum distance between two vertax is n-1

D. lie in the same plane.</span><span>
The definition of capillarity is that points are considered as co-planar when these points are on the same plane, so it is obvious that the answer D is true because this statement is the definition of capillarity. This is shown in Figure 1.

A. lie on the same line.</span><span>
If four points lie on the same line then there will be a plane that contains this line, therefore the definition is fulfilled. This is shown in Figure 2.
</span><em>Finally, the correct answers are A. and D.</em>
