2 answers:
Answer:
The correct option is 3.
Step-by-step explanation:
James made the body of a robot out of two cubes.
The side length of larger cube is 10 in. The sum of side length of both cubes is 16 in. So, the side length of smaller cube is
The side length of smaller cube is 6 in.
The volume of cube is
Where, a is side length.
The volume of smaller cube is
The volume of larger cube is
The volume of body of a robot is
The volume of body of a robot is 1216 in³. Therefore the correct option is 3.

Answer:
34
Step-by-step explanation:
The mean is calculated as
mean =
let x be the missing frequency, then
Total frequency × midpoint
= (16 × 2) + 7x + (20 × 12) + (10 × 17) = 32 + 7x + 240 + 170 = 442 + 7x
Total frequency = 16 + x + 20 + 10 = 46 + x, thus
= 8.5 ( cross- multiply )
442 + 7x = 8.5(46 + x)
442 + 7x = 391 + 8.5x ( subtract 8.5x from both sides )
442 - 1.5x = 391 ( subtract 442 from both sides )
- 1.5x = - 51 ( divide both sides by - 1.5 )
x = 34
The missing frequency is 34
