The table below lists the results of a survey which explored the
food expenditures of seven families. The survey was developed to
determine if there was a correlation between monthly income and
food expenditure. Which variable is the dependent
variable?
| Monthly Income ($) | Food Expenditure ($) | ||
| 2300 | 100 | ||
| 2800 | 950 | ||
| 3700 | 1400 | ||
| 4500 | 1500 | ||
| 2100 | 900 | ||
| 3200 | 1300 | ||
| 3000 | 1100 | ||
Multiple Choice
-
Monthly income
-
The seven families
-
Food expenditure
-
There is no dependent variable
Homework Answers
The dependent variable is -
ans-> Food expenditure
since correlation study usually has a causal relationship, to predict food expenditure, one will use monthly income.

5. The Martian atmosphere consists mainly of carbon dioxide with an average surface pressure of 700. Pa and an average temperature of -57 °C. A piston-based compressor is being designed to take ambient Martian gas and increase the pressure to 2.2 bar before it is processed for rocket fuel. CO2 is not CPG at these conditions -- you can assume it to ONLY be a TPG gas. a. Assuming the Mars atmosphere is pure CO2 and the compression process is...

4. A piston/cylinder contains pure oxygen at ambient conditions 20°C, 100 kPa. The piston is moved to a volume that is seven times smaller than the initial volume in a polytropic process with exponent n = 1.25. Find the final pressure and temperature, the specific work, and the specific heat transfer. Use table A.8 to find the internal energy at each state. Plot the process in a P – v diagram. 300 TABLE A.8 Ideal Gas Properties of Various Substances,...
