Suppose the length of songs in my playlist are uniformly distributed between 2.5 and 5 minutes. What is the standard deviation? Round answer to 3 decimal places (i. e. 0.123) If I sample 10 songs, what is the probability that the average song length is more than 3.5 minutes? Round answer to 3 decimal places (1.e. 0.123)

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.
