96 squares
(wall area)/(square area) = (24 ft²)/(1/4 ft²) = 24×4 = 96 . . . . squares
a) The population is all of the flights belonging to the particular airline. It's not all flights in general because the airline does not have control over a rival company's flight schedule.
------------------
b) The sample is the 5 airlines the company selected. Ideally the sample should represent the population as much as possible. The larger the sample, the more representative the sample is.
------------------
c) No, the sample is likely <u>not</u> representative because one day of flight does not represent the entire lifetime of all flights done so far for that company. This particular day could have been a very good day with good weather, which may explain why the 5 flights were all on time.
------------------
d) It would be better for the company to select the days at random and sample all of the flights for those particular days chosen. This is a cluster sample. Each cluster is a day. Also, I think more flights should be sampled. Five flights does not seem like enough.

Step-by-step explanation:
Sine (Angle K) / side k = sine (105) / 4.7
Sine Angle K = (2.7 * 0.96593) / 4.7
Sine Angle K =

Angle K = 33.704 degrees
Angle J = 180 -105 -33.704 = 41.296
Sine J / side (j) = sine (105) / 4.7
Sine (41.296) / side (j) = 0.96593 / 4.7
Side (j) = Sine (41.296) / 0.96593 / 4.7
Side (j) = 0.65995 /
