Step-by-step explanation:
7x-14-2x+6 = 5x - 8
Put the numbers in order
19,23,26,28,28,30,31,35,38,40,43,46
minimum = 19
maximum = 46
Q1 =(26 + 28)/2 = 54/2 = 27
Q2 (median) = (30 + 31)/2 = 61/2 = 30.5
Q3 = (38 + 40)/2 = 78/2 = 39
range = max - min = 46 - 19 = 27
Interquartile Range (IQR) = Q3 - Q1 = 39 - 27 = 12

Answer:
BD = 3.75 units
Step-by-step explanation:
Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is
= , substitute values
= ( cross- multiply )
8 BD = 30 ( divide both sides by 8 )
BD = 3.75 units
