Answer:
Step-by-step explanation:
I assume that XY is midsegment of a triangle, then MO = 2 XY
9x - 20 = 2( 3x - 4 )
9x - 20 = 6x - 8
3x = 12
x = 4
MO = 9(4) - 20 = 16 units
The answer should be b=111
Answer:
Step-by-step explanation:
3,9,12,(15),16,18,21
mean (middle number) = 15
Q1 = 9.....the middle number of the numbers before the mean
Q3 = 18...the middle number of the numbers after the mean
interquartile range (IQR) = Q3 - Q1 = 18 - 9 = 9 <==
