Mean absolute deviation: The average distance from each number in the set to the mean of the set.
Mean of the set:

9.6-3=6.6
9.6-8=1.6
10-9.6=0.4
12-9.6=11.4
15-9.6=5.4
Mean of 6.6, 1.6, 0.4, 11.4, and 5.4:
Answer:
1372 cubic ft.
Step-by-step explanation:



Since pi is 3 to find the approximate answer, do:


Hence, the volume of the sphere is approximately 1372 cubic ft.
Electronegativity<span> is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most</span>electronegative<span> element) is assigned a value of 4.0, and values range down to caesium and francium which are the least </span>electronegative<span> at 0.7.</span>
