Write a program that asks the user to enter 3 grades and computes the minimum and the maximum of those 3 grades and prints it. Hint: Use the Math.min() and Math.max() methods. This program will compute the smallest and highest of 3 grades entered by the user.
Enter 3 grades separated by a space: 100 85.3 90.5
Smallest: 85.3
Highest: 100.0

A 700 gram ball is thrown from the top of a 25 meter tall
building. The ball is thrown with an initial speed of 10 m/s at an
angle 30 degrees above the horizontal. For our conservation of
energy calculations, we will choose the Ball + Earth as our system
and use the ground as h = 0.
The kinetic energy of the ball when it is thrown
= J.
When the ball reaches its highest point the kinetic energy is NOT
zero. At the highest point the ball's kinetic energy
= J.
At the highest point, the gravitational potential energy
= J.
The maximum height the ball reaches = m above the
ground.
When the ball reaches the ground, its speed
= m/s.

Alternative problem E Goodwin Company has three segments: 1, 2, and 3. Data regarding these
segments follow:
Segment 1 Segment 2 Segment 3
Contribution to indirect expenses $ 432,000 $ 208,800 $ 72,000
Assets directly used by and identified
with the segment 3,600,000 1,440,000 360,000
a. Calculate the return on investment for each segment. Rank them from highest to lowest.
b. Assume the cost of capital is 10% for a segment. Calculate the residual income for each
segment. Rank them from highest to lowest.
c. Repeat (b), but assume the desired cost of capital is 14 per cent. Rank the segments from highest
to lowest.

Income Gap Growing In 2009, people in the highest quintile had 24.6 times as much market income as those in the lowest quintile, but after taxes and transfers the people in the highest quintile had 9.1 times as much income as those in the lowest quintile. In 1989, the people in the highest quintile had 7.2 times more income after taxes and transfers than those in the lowest quintile. In 1990, 82.9 percent of the unemployed received unemployment benefits. In 2009, 47.8 percent of the unemployed received unemployment benefits. Source: Conference Board of Canada, July 13, 2011
How have changes in employment insurance changed the income gap between the richest and the poorest Canadians?

By studying seismic measurements and geological evidence,
scientists have made the following obser
vations about earthquakes. i. Small tremors (magnitude below 1.0 on
the Richter scale) are almost constantly oc
curing on every continent.
ii. The number of earthquakes with magnitude at least 3.0 on the
Richter scale averages
200,000 per year, worldwide.
iii. Based on geological evidence, the number of major earthquakes
(magnitude> 7.0 on
the Richter scale) has averaged 20 per year, and this average rate
has not changed over
the last 10,000 years.
iv. The number of earthquakes occurring each year is independent of
the number that
occurred in any previous year.
v. The magnitude of an earthquake is inversely proportional to the
logarithm of the
frequency that earthquakes of at least that magnitude occur. In
other words, let
X(m) denote the expected number of earthquakes per year with
magnitude greater
than or equal to m. Then logX(m) is proportional to m.
(a) Explain why it is reasonable to use a Poisson random variable
to model the number of major
earthquakes occurring in any given period of time? Indicate which
of the above observations
support your explaination.
(b) Let N(t) be a Poisson random variable that models the number of
major earthquakes (magnitude
> 7.0) that will occur in the next t years. Give the probability
mass function for N(t).
(c) Calculate the expected value and standard deviation for
N(3).
(d) Calculate the probability that there will be at least 3
earthquakes in the next month.

Consider a 10.00 L cylinder divided by an adiabatic piston. Side
A contains Ar at PA1 = 2.00
atm, VA1 = 5.00 L, and TA1 = 500K. Side B contains Ne at PB1 = 2.00
atm, VB1 = 5.00 L,
and TB1 = 500K. Side B is completely adiabatic and closed. Side A
is maintained isothermal
and has a small hole in the end, which is plugged by a stopper.
When the stopper is pulled,
the Ar in Side A can be pushed out by the pressure from Side B
until the pressure on Side A
equals the pressure outside (1.00 atm).
(a) Calculate the final conditions on both sides.
(b) Calculate q, w, ∆U, ∆H, and ∆S for both sides. You can assume
that the process is
reversible.
