Find and interpret the marginal frequencies.

A marginal relative frequency can be calculated by dividing a row total or a column total by the Grand total.

Step-by-step explanation:Marginal relative frequency is one of the types of relative frequency that we can obtain from a two-way frequency table.

A marginal relative frequency can be calculated by dividing a row total or a column total by the Grand total.

Circumcenter is where three perpendicular bisectors intersect and incenter is where the three angle bisectors intersect.

Way to find them and the theorems are mentioned below.

Step-by-step explanation:

To find Incenter :

Construct angle bisectors of each angle of the triangle and their intersection  point gives the incenter.

To find Circumcenter:

Construct perpendicular bisectors of all sides of triangle and their intersection point gives the circumcenter.

Circumcenter Theorem: It states that the vertices of a triangle are equidistant from the circumcenter.

Incenter Theorem: It states that the incenter is equidistant from the sides of the triangle.
