you are given a motor operated by a 9V battery. The stall torque
for this motor is Ts = 0.04 N-m, and its
no-load speed, wnl = 2200 rpm.
You are given a 10-tooth gear, a 20-tooth gear, and a bunch of
axles (shafts).
Draw below how will you connect the gears and shafts so that
output shaft has a higher torque than the motor
shaft.
Label in your diagram, which gear is the input (driver), and which
is the output (driven). ...

You are given the following total cost function for a firm:
TC
= (25+F) + L x Q + 0.5 x (Q2)
where F=the number of the letter of
the alphabet corresponding to the initial of your first name, and
L=number of the letter of the alphabet corresponding to the initial
of your last name. For example, if your name were Bill
Weber, F=2 and L=23, so
TC = 27 + 23 x Q + 0.5 x
Q2.
a. Calculate
TC, TFC,...

How much money do you think you would earn in a period of 30
days if you were paid as follows: one cent for the first day, two
cents for the second day, four cents for the third day, eight cents
for the fourth day, and so on (i.e. your salary doubles each day)?
Do you think you would make very little money, just a few dollars,
at the end of the 30-day period? Let us write a program to...

THIS IS THE GENERAL EQUILIBRIUM PROBLEM THAT I PROMISED. YOU
FIRST SOLVE FOR THE INITIAL EQUILIBRIUM AS POINT A. WE CONSIDER TWO
DIFFERENT AND SEPARATE SHOCKS (I CALL THEM SCENARIOS). THE FIRST
SHOCK IS TO THE IS CURVE, THE SECOND SHOCK IS A ‘LM’ SHOCK. AGAIN,
WE CONSIDER THESE SHOCKS SEPARATELY SO THAT AFTER YOU COMPLETE
SCENARIO 1 (THE IS SHOCK), WE GO BACK TO THE ORIGINAL CONDITIONS
AND CONSIDER THE SECOND SCENARIO WHICH IS THE ‘LM’ SHOCK.
Consider the...

2) Airline accidents: According to the U.S. National
Transportation Safety Board, the number of airline accidents by
year from 1983 to 2006 were 23, 16, 21, 24, 34, 30, 28, 24, 26, 18,
23, 23, 36, 37, 49, 50, 51, 56, 46, 41, 54, 30, 40, and 31.
a. For the sample data, compute the mean and its standard error
(from the standard deviation), and the median.
b. Using R, compute bootstrap estimates of the mean, median and
