Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

QUestion15
The diagram features two quadrilaterals on a coordinate plane:
1. Quadrilateral \(ABCD\) positioned in the first quadrant.
2. Quadrilateral \(JKLM\) positioned in the third quadrant.
### Axes:
- **X-axis**: Horizontal axis of the coordinate plane
- **Y-axis**: Vertical axis of the coordinate plane
### Vertices:
- **\(ABCD\)**:
- \(A\) is positioned at top right.
- \(B\) is located slightly below and to the left of \(A\).
- \(C\) is below \(B\).
- \(D\) is to the right of \(C\).
- **\(JKLM\)**:
- \(J\) is positioned to the top right.
- \(K\) is to the left of \(J\).
- \(L\) is below \(K\).
- \(M\) is right of \(L\).
### Given Angles:
- \(\angle A = 82^\circ\)
- \(\angle B = 104^\circ\)
- \(\angle L = 121^\circ\)
### Unknown Angle:
- \(\angle M\)
The task is to determine the measure of \(\angle M\).
Given the angles and the nature of rigid motions, which preserve angles and relative side lengths:
- Rigid motions include translations, rotations, and reflections.
- The sum of angles in any quadrilateral is \(360^\circ\).
### Calculation:
Sum of angles in \(JKLM\):
\[ \angle J + \angle K + \angle L + \angle M = 360^\circ \]
Given:
\[ \angle J \equiv \angle A = 82^\circ \]
\[ \angle K \equiv \angle B = 104^\circ \]
\[ \angle L = 121^\circ \]
To find \(\angle M\):
\[ 82^\circ + 104^\circ + 121^\circ + \angle M = 360^\circ \]
\[ 307^\circ + \angle M = 360^\circ \]
\[ \angle M = 360](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffeb8ca9d-9969-400c-8a44-95370ebd76d8%2F635757d9-d650-43ab-a651-64e0947897c7%2Faf9ems_processed.png&w=3840&q=75)
