Answer:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Step-by-step explanation:
The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.
The average number of newspapers for sale in an airport stand is 15. SD is 6.
The consistency is:

The average age of the pilots is 36 and SD is 4.
The consistency is:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Answer:
Step-by-step explanation:
I'm ASSUMING this goes with a photo supplied in another question.
Part E reflection across the x axis leaves the x value identical but negates the y value (x, y) → (x, -y)
Part I translating 6 up and 1 left subtracts one from the x value and adds 6 to the y value (x, y) → (x - 1, y + 6)
Part K Chanel has the correct sequence as following her instructions maps each point on triangle ABC perfectly to triangle DEF
Preston was close but he either needed to rotate about the origin 180° then translate up 6 and left 1, or rotate 180° about the point (-½, -½) and translate up 7.
I think the quickest conversion is to rotate 180° about the point (-½, 3)
