Answer:
5 Outer and 1 lone pair
Step-by-step explanation:
A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.
Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is 
.
One of the most common example is Xenon tetraflouride. 
. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
Quotient means divide, so the expression would be r/3, I believe
hope it helps
Answer:
OP = 3 units
Step-by-step explanation:
Point O is on line segment NP.
Therefore, N - O - P
So,
NO + OP = NP
15 + OP = 18
OP = 18 - 15
OP = 3 units
