12 will be opposite to 24. Then the number of the people are sitting at the table will be 24.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The several people are sitting evenly spaced around a circular table and the positions are labelled 1, 2, 3 and so on.
The people at positions 3 and 15 are directly opposite each other.
Then the number of the people are sitting at the table will be
1 is opposite to 13
2 is opposite to 14
3 is opposite to 15
Similarly, 12 will be opposite to 24.
Then the number of the people are sitting at the table will be 24.

Answer:
Step-by-step explanation:
Note that closed dot means that it is included inside. Look at the direction of the arrow, it will give you the knowledge of which way the sign will face.
10) x ≥ -1, or (4)
Note that the point is at -1 (-1), The arrow is also traveling towards the greater side (>). Note that the dot is 'colored in', or closed. If the dot is closed, the number the dot is on is included inside, leading to the sign having an equal sign on the bottom.
11) -4 ≤ x < 2, or (2)
As stated above ≤ means <em>closed dot</em> (or included). x is greater than -4, and so -4 is ≤ x. However, note the dot on the 2. It is not colored in. This means that 2 is not included inside the solution, leading to the usage of <.

Complete options are;
A) Paired t-test for means
B) Paired Z-test for means
C) Z-test for proportion
D) t-test for means
E) Z-test for means
F) t-test for proportion
Answer:
B) Paired Z-test for means
Step-by-step explanation:
We are told that the distances travelled are normally distributed.
We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.
Also, the standard deviation of both cases are known.
Thus, this is where Paired Z-test for means is used.
