The interquartile range (IQR) is greater for M's classes than J's classes.
Step-by-step explanation:
<u>J's Classes:</u>
23, 25, 27, 28, 32
Median: 27
Mean: 27
Mean Absolute Deviation: 2.4
Interquartile Range: 3

Answer:
Step-by-step explanation:
<h3>
Convert kilometer to miles:</h3>
1 km = 0.62 mi
So, to convert 6 km to mi, multiply 6 by 0.62.
6km = 6* 0.62
= 3.72 mi
<h3>Convert liter to gallon:</h3>
1 L = 0.26 gal
To convert 2.5 L to gallon, multiply 2.5 by 0.26.
2.5 L = 2.5 * 0.26
= 0.65 gal
<h3>Convert pound to kilogram:</h3>
1 lb = 0.45 Kg
To convert 90 lb to Kg, multiply 90 by 0.45.
90 lb = 90 *0.45
= 40.5 Kg
A = 8B
A + B = 180
8B + B = 180
9B = 180
B = 20
A = 8 * 20 = 160
