Answer:
Step-by-step explanation:
Assuming that all of the 255 sold seats were filled, then

(225/260)*100=86.53%
100%-86.53%=13.4%
13.4% of seats are empty!
Answer: D
Step-by-step explanation:
A= π*r² = π*7.3² ≈ 167.4154725
A. In this case, they can be arranged at any order. Since
there are 7 people all in all, therefore the number of arrangements is:
number of arrangements = 7P7 = 5040 ways
B. In this case, only the 5 people can be arranged in any
