Question 1
The time-based dependence of a system's output on present and past inputs (its "memory") is known as:
a) Memory
b) Gain
c) Hysteresis
d) Sampling period
Question 2
Identify the following features of the chart shown:
a) Upper control limit (UCL)
b ) Lower control limit (LCL)
c) Error
d) Setpoint
Question 3
The setpoint, provided by your instructor, will be:
a) in salinity percentage
b) always the same as the current salinity concentration
c) in arduino reading
d) always above the UCL
Question 4
PID is a common acronym in control theory. In PID, the letter "P" stands for:
a) Power
b) Phase
c) Process
d) Proportional
Question 5
In the fishtank system, one reasonable assumption might be:
a) The difference in density between the incoming and outgoing water is negligible.
b) The salinity of the water in the fishtank will never exceed 15%
c) Your instructor will grade you leniently
d) The UCL will always be at least 2.5V higher than the the LCL.
Draw the lines-shade out a feasable region
: Maximize and minimize p = 2x-y with respect to x+y ≥ 2, x+y ≤ 10, x-y ≥ -2 and x-y ≤ 2. (Draw the lines, shade out a feasable region, look at boundary points)

Number in the data set
: A data set has a median of 41, and four of the numbers in the data set are less than median. The data set contains a total of n numbers. If n is odd, and exactly one number in the data set is equal to 41, what is the value of n?

Identify components of sociocultural theory
: This essay invites you to identify components of sociocultural theory (stemming from the work of Vygotsky) to real life educational settings. To do this, first watch the Tinkering School TED Talk video from Gever Tulley (http://www.ted.com/talks/..
