The number of 1/3 cm-cubes that would fill the rectangular prism is approximately 20 cubes.
<h3>What is the Volume of a Cube?</h3>Volume = a³, where a is the side length.
<h3>What is the Volume of a Rectangular Prism?</h3>Volume = lwh
Given the following:
- a = ⅓ cm
- l = 4/2 cm = 1/2 cm
- w = 2/2 cm = 1 cm
- h = 3/2 cm
Volume of the rectangular prism = (1/2)(1)(3/2)
Volume of the rectangular prism = (1/2)(1)(3/2) = 0.75 cm³
Volume of the cube = (⅓)³ = 0.037 cm³
Number of cubes that would fill the prism = 0.75/0.037 ≈ 20 cubes.

Answer: The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river.
Step-by-step explanation:
The standard deviation of the sampling distribution = , where p= population proportion and n = sample size.
Let p be the proportion of fish in a river are catfish.
As per given , we have
p= 0.47
n= 25
The, the standard deviation of the sampling distribution will be
The 10% condition : Sample sizes should be no more than 10% of the population.
But a river can have more than 250 fish [where 10% of 250 =25 (sample size)]
i.e. The 10% condition is met because it is very likely there are more than 250 fish in the river.
So the correct answer is "The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river."
