What is the volume of the composite figure? Answers:
192ft^3
96ft^3
76ft^3
152ft^3

68 ft³

Step-by-step explanation:

Take the above figure to be 2 rectangular prism. A smaller prism on top, and a bigger one under.

Volume of the smaller rectangular prism on top:

Where,

w = 2 ft

h = 4 ft

l = 4 ft

Volume of bigger Rectangle prism under:

w = 2 ft

h = 3 ft

l = 6 ft

Volume of composite figure = 32 + 36 = 68 ft³

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

$12. that is my answer.
