Answer:
Explained below.
Step-by-step explanation:
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normal.
Then, the mean of the sampling distribution of sample means is given by,
And the standard deviation of the sampling distribution of sample means is given by,
So, if the sample of daily calcium intake of Americans collected is more than 30, then the sampling distribution of 
will be approximately normal.
If you would like to solve the equation 9/11 = x/22, you can calculate this using the following steps:
9/11 = x/22 /*22
x = 9/11 * 22
x = 18
The correct result would be 18.
2/6 = 1/3
2/5 = 4/10
Hope this helps.
Answer: A 40 feet
Explanation:
If a building is 380 feet tall and the elevator has to descend 420 feet to get to the underground parking garage. So 420 - 380 to remove the height of the building from the equation. This would give us 40 feet underground left until the elevator reaches its desired destination.
