Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences ab
out the characteristics of a population. Suppose that, from a population of 52 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible

The question is incomplete. The complete question is :
Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below. What is the total number of cubes that Georgia needs to exactly cover the bottom of the box with a layer one cube deep?
Solution :
It is given that :
There are small cubes that has a dimension of 4 in x 4 in x 4 in.
There is also a box which has a dimension of 24 in x 20 in x 12 in.
We need to find out how many small cubes will Georgia need to cover the bottom of the box.
So, we need to find out the surface area of the one cube and the box.
Therefore, the surface area of one cube = side x side
= 4 inch x 4 inch
= 16 square inches
Similarly the area of the box can be find by = length x breath
= 24 in x 20 in
= 480 square inches
Therefore, dividing the area of the box by the area of the cube, we get
= 30
So Georgia will require exactly 30 cubes to cover the bottom of the box with a layer of one cube deep.
Answer:
x = 0 , 3
Step-by-step explanation:
x = 0 ; x - 3 = 0
x = 0 ; x = 3
