Answer:

$x = - 3 \: \: and \: \: x = - 11$

Step-by-step explanation:

$- 3 |x + 7| = - 12 \\ |x + 7| = ( - 12) \div ( - 3) \\ |x + 7| = 4 \\ 1. \: x + 7 = 4 \: \: \: 2. \: x + 7 = - 4 \\ \: \: \: \: x = 4 - 7 \: \: \: \: \: \: \: \: x = - 4 - 7 \\ \: \: \: \: x = - 3 \: \: \: \: \: \: \: \: \: \: \: \: x = - 11$

The central tendency researcher use to describe these data is "mode".

The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.

Calculation of mode is done by-

The number that appears the most frequently in a piece of data is its mode.
Put the numbers in ascending order by least to greatest, then count the occurrences of each number to quickly determine the mode.
The most frequent number is the mode.
Simply counting how many times each number appears in the data set can help you identify the mode, which is the number that appears the most frequently in the data set.
The figure with the largest total is the mode.
Example: Since it happens most frequently, the mode for the data set [5, 7, 8, 2, 1, 5, 6, 7, 5] is 5.

O is parallel to q

let's take the angle opposite to angle 4 is alpha

angle 4 = angle alpha ( vertically opposite angles)

angle alpha = angle 3 ( as angle 4 = angle 3).

hence o is parallel to q as both the angles are equal
