An ellipse has a major semi-axis of 20 cm and a minor semi-axis of 14 cm. find the area.

avanturin [10]

In order to answer the question, you need to know the formula area of an ellipse.

Area = pi * a * b
a = minor axis
b = major semi-axis

Area = 3.14 * 20 * 14
Area = 879.20 cm^2

Bob constructed an equilateral triangle PQR as shown. He then drew a straight line ST THROUGH POINT P. Determine the sum of the

prohojiy [21]

The answer would be 120 because point p is 60 degrees, since the triangle is an equilateral triangle. Then you would do 180-60, which is 120.

A(n) ______ specifies the phenomena of interest; indicates which variables are independent, alternative, antecedent, intervening

Nana76 [90]

Answer:

An arrow diagram

Step-by-step explanation:

Helps keep track of intricate relationships between variables. Specifies the phenomena of interest: independent, alternative, antecedent and intervening.

-Time on the bottom with an arrow

-Antecedent -> Independent -> intervening-> dependent

An arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their inter-connectivity. It is a network diagramming technique in which activities are represented by arrow, used for scheduling and to determine the critical path through nodes. The arrow diagramming method shows the required order of tasks in a project or process, the best schedule for the entire project, and potential scheduling and resource problems and their solutions. The arrow diagram lets you calculate the "critical path" of the project the flow of critical steps where delays can affect the timing of the entire project and where addition of resources can speed up the project.

One headed arrow connecting two variables= "X directly causes Y"
