Answer:
<em>B.</em><em> Mean: 339.20 (Median: 318) (Mode: 445.20) (Range: 243.80)</em>
Step-by-step explanation:
A store sells models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00.
As a 6% tax will be levied on this as sales tax, the new prices will be, $201.40, $445.20, $286.20, $318, $445.20
Arranging them in ascending order,
201.40, 286.20, 318, 445.20, 445.20
Mean of the sample will be,
Median is the middle value of the sample. So median will be 318.
The highest number of occurrences is the mode of the set. So mode is 445.20

Given:
A figure of combination of hemisphere, cylinder and cone.
Radius of hemisphere, cylinder and cone = 6 units.
Height of cylinder = 12 units
Slant height of cone = 10 units.
To find:
The volume of the given figure.
Solution:
Volume of hemisphere is:
Where, r is the radius of the hemisphere.
Volume of cylinder is:
Where, r is the radius of the cylinder and h is the height of the cylinder.
We know that,
[Pythagoras theorem]
Where, l is length, r is the radius and h is the height of the cone.
Volume of cone is:
Where, r is the radius of the cone and h is the height of the cone.
Now, the volume of the combined figure is:
Therefore, the volume of the given figure is 2110.08 cubic units.
