5/10 if you want it simplified it would be 1/2, because 1,3,5,7,9 are prime numbers so there are 5 of them out of the 10 numbers.
Answer:
49 +80= 129
180 - 129= 51
Opposite are equal.
Extend line of QR - so, the x shape made can be used to calculate what x is.
51 + 51 = 102
Reflex angles adds to 360
360-102= 258 of the other opposite angles left.
258/2 = 129 since opposite angles are equal.
Answer is 129 degrees

<em>If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).</em>

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.
