Help me with my 2 math questions and I’ll mark brainliest !!

-Define cluster and stratified sampling. Give an example of each. Do not use an example from the Performance Exam Review.

-Identify the shape of the distribution for the following histograms. Label the mean and median using A and B for each histogram. Explain your reasoning for the mean and median placement.

(x, y)→(x − 8, y − 7)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
