Answer:
The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For the population, we have that:
Mean = 0.5
Standard deviaiton = 0.289
Sample of 12
By the Central Limit Theorem
Mean = 0.5
Standard deviation 
The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.
Answer:
Area of one face of the cube is 
Step-by-step explanation:
A cube is a three dimensional figure that has all of its sides equal.
A cube has six square faces:
Surface area of the cube = 
where 'a' is the side length of the cube:
Area of one face of a cube= 
For surface area of the whole cube: 500 square inches
Dividing by '6' both sides;
Area of one face of the cube is
Width=19
Length=17
72-4=68/2=34/2= 17 length
72-4=68+4=38/2=19 width
