What is the MEAN?
300
considerations and concerns that NASA design engineers take into account in order to answer ethical questions related to their work on space shuttles.
What are: Will the shuttle be able to fly? How much will the project cost? Could the money be used in other ways that would benefit society more?
300
an INVERSE nonlinear relationship
What is a trend in a nonlinear graph in which the dependent variable decreases as the independent variable increases.
