Answer:
b=4
<XQL= 62*
<MQR=62*
<XQM=118*
<LQR=118*
Step-by-step explanation:
the best answer is b
12.
First arrange in ascending order:
2 5 8 10 14 17 21
The median is 10.
the lower quartile is the middle number of 2 5 and 8 which is 5.
Similarly the upper quartile is 17.
IQR = 17 - 5 = 12.
the last one. f(n) - 3; for n ≥ 1
