Assuming that all stations are occupied and all lines are observed in both directions, compute the strength of figure factor for a quadrilateral with interior station.
- 0.44
- 0.54
- 0.64
- 0.74
\[
c = (n’ – S’ + 1) + (n – 2s + 3)
\]
\[
c = (8 – 5 + 1) + [8 – 2(5) + 3]
\]
\[
c = (8 – 5 + 1) + (8 – 10 + 3)
\]
\[
c = 5
\]
\[
F = \frac{D – c}{D}
\]
\[
F = \frac{14 – 5}{14}
\]
\[
F = 0.64 \leftarrow \text{answer}
\]
