Answer:
a = 138
Step-by-step explanation:
Notice that from the figure, we can see that ∠MOQ and ∠PON are vertical angles, which means that by definition, they're congruent in measure.
∠MOQ = ∠MOR + ∠ROQ = 90 + 48 = 138°
So, this means that ∠PON is also equal to 138, which means a = 138.
Thus, the answer is a = 138.

Answer:
The answer is: When the sample mean is not a whole number.
Explanation:
The "Sum of Squares" <em>(SS)</em> refers to the measure of the distance from the mean. This can be computed by subtracting each of the measurements from the mean. The difference will then be squared and the measurement results will be added together. This formula is known as "definitional formula." This is preferably used when the mean is a whole number and there are only a few number of scores.
On the contrary, the "computational formula" allows the calculation of the concept values. This is preferably used when the mean is not a whole number and when there are many scores.

Using proportions, it is found that the interval for the number of times Elliot must visit his parents is [14, 41].
---------------------
- The interval is found using proportions, by a rule of three.
- In each visit to his parents, Elliot flies 350 miles.
- To qualify for Gold status, he must fly at least 4900 miles. How many trips are this:
1 trip - 350 miles
x trips - 4900 miles
Applying cross multiplication:
![350x = 4900](https://tex.z-dn.net/?f=350x%20%3D%204900)
![x = \frac{4900}{350}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4900%7D%7B350%7D)
![x = 14](https://tex.z-dn.net/?f=x%20%3D%2014)
He must visit his parents at least 14 times.
---------------------
- Also less than 14700 miles, how many trips are this?
1 trip - 350 miles
x trips - 14700 miles
![350x = 14700](https://tex.z-dn.net/?f=350x%20%3D%2014700)
![x = \frac{14700}{350}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B14700%7D%7B350%7D)
![x = 42](https://tex.z-dn.net/?f=x%20%3D%2042)
Less than 42 trips, thus at most 41 times.
The interval is [14, 41].
