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"

Answer:
The amount invested are $2600 and $11400 respectively
Step-by-step explanation:
<em>Let the first amount be x</em>
Given:
(First Investment)
Principal (P1) = x
Rate (R1) = 4.5%
Time (T) = 1 year
(Second Investment)
Principal (P2) = 4x + 1000
Rate (R2) = 6%
Time (T) = 1 year
Income = $801
Calculating the income from the first investment;
Substitute values for P1, R1 and T
Calculating the income from the second investment;
Substitute values for P2, R2 and T
So:
Multiply through by 100
Collect Like Terms
Divide through by 28.5
Recall that; the second invest
Amount Invested = 4x + 1000
This gives
Hence;
<em>The amount invested are $2600 and $11400 respectively</em>
