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:
An equation represents the number of pieces of lasagna that are left after dinner is
Step-by-step explanation:
Each piece of Lasagna is 1/6 of the pan
Let x be the number of pieces left
So, x pieces is of the pan
We are given that After dinner 2/3 of a pan of lasagna is left.
So,
x=4
So, Number of pieces left = 4
Hence An equation represents the number of pieces of lasagna that are left after dinner is
Answer:
2/3 and -1/3
Step-by-step explanation:
We have to find which two numbers on the number line are at a distance of 1/2 from 1/6.
The two numbers that are 1/2 units away from 1/6 will be:
1)
2)
Thus the two numbers are: 2/3 and -1/3
Answer:
Option A
fraction numerator square root of 2 over denominator 2 end fraction
Step-by-step explanation:
The answer can be obtained using a calculator.
It corresponds to a notable identity
sin (45) = / 2
sin (45) = 0.7071
/ 2 = 0.7071
