Answer:
Rectangular Cuboid
Step-by-step explanation:
A rectangular cuboid has 4 faces that are rectangles and 2 faces that are squares. Since a square is a rectangle, this shape is technically built of 6 rectangles and is creates a 3-dimensional shape. Hence, we have the prism, rectangular cuboid.
Answer:
C) 201
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming n > 30, we can approximate CV with a normal distribution. At P = 99%, CV = 2.576.
SE = σ / √n
SE = 1100 / √n
Therefore:
200 = 2.576 × 1100 / √n
n = 201
Answer: Bladder
Step-by-step explanation:
The walls of the bladder contain very few blood vessels and are lined with guanine crystals, which make them impermeable to gases. By adjusting the gas pressurising organ using the gas gland or oval window the fish can obtain neutral buoyancy and ascend and descend to a large range of depths.
