Step-by-step explanation:
To get from point (4,4) to (10,10), it is the same as ordering 6 Upward and 6 Right arrows in a straight line.
=> 12C6 = 924.
However there is a restriction that we cannot have 3 Upward and 3 Right arrows as our first 6 arrows.
=> 6C3 * 6C3 = 20 * 20 = 400
Hence there are 924 - 400 = 524 different ways.

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.
Answer:
45
Step-by-step explanation:
The 4 part of the ratio represents Pip's 20 sweets
Dividing 20 by 4 gives the value of one part of the ratio
20 ÷ 4 = 5 sweets ← value of 1 part of the ratio
Thus
Pip gets 20 sweets
Angad gets 20 sweets ( 4 parts of the ratio )
Nick gets 5 sweets ( 1 part of the ratio )
Total number of sweets = 20 + 20 + 5 = 45
