Find the first quartiles (Q1) of the following sets of data. (i) 14, 12, 17, 23, 20, 16, 10
(ii) 16, 25, 10, 30, 35, 8, 12
(iii) 40,20,30,10,16,12,18,24

(i) 28. (ii) 34. (iii) 42.5

Step-by-step explanation:

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

im guessing (23,14). hope this : )
