Answer:
The value of x is 4
Step-by-step explanation:
we know that
in this problem

solve for x




y=mx+b where m is the slope and b is the y intercept.
The answer is d) 6 * 3 + 2 =x
Put the numbers in order...
4,5,6,6,7,8,9,9,10,10,12,12,14,15
Q1 = (6 + 6) / 2 = 12/2 = 6
Q2 (median) = (9 + 9)/2 = 18/2 = 9
Q3 = (12 + 12) / 2 = 24/2 = 12
Q3 - Q1 = 12 - 6 = 6 (this is actually the interquartile range (IQR)
