The statement is that "all the primary types of project life cycle models contain a sequence of precisely four phases with tasks. It must be finished and permissions must be obtained before the project can go on to the next phase, despite differences in the specifics" is true.
<h3>What is a model?</h3>
A model is an artificial 3D representation of a process of objects. Models can be small and large. Models are made to give information about things that are very big or undone in reality.

Coefficient of variation can be regarded as the method that is usually devices in the assessment of the total risk per unit of return in a particular investment.
To calculate the investment's coefficient of variation, we use the expresion below
Coefficient of variation = standard deviation/expected return.
Given:
expected return = 15%
standard deviation = 10%.
Coefficient of variation =10/15
= 0.67
Hence, the investment's coefficient of variation is 0.67
