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.

Answer:
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure <em>Part</em><em> </em><em>A</em><em> </em>out:
180° = 22° + x° + 104°
180° = 126° + x°
-126° - 126°
___________
54° = x
_______________________________________________
The measure of ∠C and the exterior angle measure of 105° sums up 180°, according to the Linear Pair Theorem:
180° = 105° +
-105° - 105°
______________
Then use the Triangular Interior Angles Theorem to figure out the :
180° = 53° + 75° +
180° = 128° +
-128° - 128°
______________
OR, you can use the Exterior Angles Theorem, which states that the exterior angle is opposite the side with two interior angles, so you would deduct the first interior angle from the exterior angle to get the measure of the second interior angle. In this case, you would deduct 53° from 105° to get 52°:
142° = 53° + m∠A
- 90° - 90°
_______________
_______________________________________________
The measure of ∠N and the exterior angle measure of 142° sums up 180°, according to the Linear Pair Theorem:
180° = 142° +
- 142° - 142°
______________
Then use the Triangular Interior Angles Theorem to figure out the :
180° = 38° + 90° +
180° = 128° +
- 128° - 128°
______________
OR, you can use the Exterior Angles Theorem, which states that the exterior angle is opposite the side with two interior angles, so you would deduct the first interior angle from the exterior angle to get the measure of the second interior angle. In this case, you would deduct 90° from 142° to get 52°:
142° = 90° + m∠M
- 90° - 90°
