Suppose That We Illustrate Demand and Supply with Quantity on the Horizontal

question 68

Multiple Choice

Suppose that we illustrate demand and supply with quantity on the horizontal axis and price on the vertical axis. Let demand be a function of price and income, Qd (P, I) . Which of the following statements is true?

• A)A change in income will cause a shift in the supply curve.
• B)A change in income level is represented by a movement along the demand curve.
• C)Income is not represented on one of the axes, and so is treated as an exogenous variable in the graphical analysis.
• D)Price and income together must change in order to create a shift in the demand curve.

ECG

Electrocardiogram, a test that records the electrical activity of the heart over a period of time, used to detect heart abnormalities.

S-T Segment

A section of the electrocardiogram (ECG) tracing between the S wave and the start of the T wave, representing the interval between ventricular depolarization and repolarization.

T Wave

A component of the ECG that represents the repolarization of the ventricles in the heart cycle.

Depolarization

A reduction in the difference in electrical charge across a cell membrane, leading to activation of the cell.
