Answer:
From the central limit theorem we know that the distribution for the sample mean
is given by:
The mean is given by:

And the deviation is given by:

Step-by-step explanation:
For this case we define the random variable X as "number of years of education of self-employed individuals in the U.S." and we know the following properties:

And we select a sample of n = 100
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
From the central limit theorem we know that the distribution for the sample mean
is given by:
Solution to the problem

Answer:
The angles are 78° and 102°.
Step-by-step explanation:
Let the one angle is y and the other number if y + 24.
The sum of the angles of the linear pair is 180°.
So, according to the question
y + y + 24 = 180
2 y = 180 - 24
2 y = 156
y = 78°
So, one angle is 78° and the other is 78° + 24° = 102°.
Answer:
A. 32 degrees
Step-by-step explanation:
Here we have to use the rule.
m∠E = 1/2 (major arc - minor arc)
m∠E = 1/2 (212 - 148)
m∠E = 1/2 (64)
m∠E = 32 degrees
Answer: A. 32 degrees
Thank you
Step-by-step explanation:
3x+6 = 90
3x = 84
x = 28
angle z = 28+6=36
angle t = 56
