[example continued…] A researcher is interested in understanding the online shopping habits of college students in the US. To answer this question, the researcher conducts a survey of 200 randomly selected college students from across the US. Of these 200 students, 138 of them (69%) reported that they regularly shop online. If the goal of the study is to discover what percentage of college students in the US regularly shop online, that number would be an example of a _________.

Question C: The following circuit has a switch that opens at t=0. The resistor R is 6 ohms, Vi is 24 volts. Answer the following questions regarding this circuit.

Assume a motor running on A, B, and C balanced currents, and their magnitude is 10A. Find the corresponding d-axis quantity using “park’s” transformation if the d-axis leads the q-axis by 90 electrical degrees; the angle is between the q and a-axis. Here, the angle is 240 degrees, and the scaling factor of the d-axis is 23.
