Parallel is MN and QP and perpendicular is MQ and OP
In the middle:
x-coordinate= {7-(-1)}/2= 4
y-coordinate= (8-2)/2= 3
So centre is (4,3)
It is given in the question that
M is the MIDPOINT OF FG.

Since M is the midpoint of FG, therefore GM is half of FG. That is


Therefore

And FM is 13 too .
Answer:
n = 61 costumers
Step-by-step explanation:
For calculating the number of costumers he should sample we use the next equation:

Where E is the error that we are prepared to accept, in this case E = 0.15
How we don't know the value of p, we can estimate it like p = 0.5
∝ = 1-0.98 = 0.02
1-∝/2 = 0.99


n = 60.32 costumers
n ≈ 61 costumers
