Answer:
15.92
Step-by-step explanation:
50 ÷ 3.14 = 15.92
Joint Frequency because of the fact that it "joins" one number from the column(up and down) and one from the row(side-by-side), hence the two-way table.
The ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity.

Definitions of dimensions in ellipses</h3>
Dimensionally speaking, an ellipse is characterized by three variables:
- Length of the <em>major</em> semiaxis ().
- Length of the <em>minor</em> semiaxis ().
- Distance between the foci and the center of the ellipse ().
And there is the following relationship:
(1)
Another variable that measure how "similar" is an ellipse to a circle is the eccentricity (), which is defined by the following formula:
, (2)
The greater the eccentricity, the more similar the ellipse to a circle.
Therefore, the ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity.
