Question

Suppose that t weeks after the start of an epidemic in a certain community, the number P(t) of people who have caught the disease is given by the logistic curve P(t) = 1500 5 + 295 e-0.9t (a) How many people had the disease when the epidemic began? (b) Approximately how many people in total will get the disease? (c) When was the disease spreading most rapidly? (d) How fast was the disease spreading at the peak of the epidemic? (e) When did the spread of the disease start to slow down? (f) What is the differential equation for P(t)? (g) By the time 200 people had had the disease, what was the rate at which the disease was spreading?

1. The number of computers infected by a virus t minutes after
it first appears usually increases exponentially. In 2000, “Love
Bug” virus spread from 100 computers to about 1,000,000 computers
in 2 hours (120 minutes).
a) Find the growth rate k.
b) Give the differential equation for the number P(t) of
computers infected after t minutes.
c) How fast was the virus spreading when 1,000,000 computers
were infected?
2. Find the slope of the tangent line to the graph...

Exponential Model: P(t) = M(1 − e^−kt) where M is maximum
population.
Logistic Model: P (t) = M / 1+Be^−MKt where M is maximum
population.
Scientists study a fruit fly population in the lab. They
estimate that their container can hold a maximum of 500 flies.
Seven days after they start their experiment, they count 250
flies.
1. (a) Use the exponential model to find a function P(t) for the
number of flies t days after the start of the...

d.

Paired sample t-test:
Suppose you are interested in deciding if a particular diet is
effective in changing people's weight. You decide to run a "within
subject" experiment. You select 6 people and weigh each of them.
Two weeks and you weigh them again. For each person you compute how
much weight they lose over this period. You find : Non-diet
(subject 1-6): 0,8,3,2,-10,-1. You then put them on the diet and
weigh them again after two weeks and compute how...

Jose and Jorge were identical twins separated at birth. Jose
grew up in a large family in an impoverished slum in the middle of
a crime-ridden and polluted district of a major city. Jorge grew up
in an upper-middle-class professional family with one other brother
in a sub urban community in the same city. Despite the fact the
Jose and Jorge were identical twins, their lives and health could
not have been more different.
Jose had few opportunities for medical...

Everyday investment company Sharesies was launched in February
2017, after conducting research on New Zealanders’ attitudes
towards investing. Prior to launching the company, the co-founders
interviewed over 200 people asking them “If I gave you $50 right
now, and you had to do something with it in the next 5 minutes what
would you do?” Only 5 out of 200 people chose an option to save or
invest the $50. More popular options were bills, online shopping,
coffees, vouchers, food,...

What makes the study of strategic management so interesting?
Things can change so rapidly! Some start-ups can disrupt
industries and become globally recognized names in just a few
years. The rankings of the world’s most valuable firms can
dramatically change in a rather brief period of time. On the other
hand, many impressive, high-flying firms can struggle to reclaim
past glory or even fail. Recall just four that begin...

There are two reflective essays from MED students during
their third year internal medicine clerkship. One student sees each
connection to a patient as like the individual brush strokes of an
artist and the other sees gratitude in a patient with an incurable
illness and is moved to gratitude in her own life. (WORD COUNT
500)
Reflect on both essays and then choose one and describe
how the student grew from the experience.
Then explain what you learned as a...
