Answer:
The differential equation for the model is
The model for P is
At half day of the 4th day (t=4.488), the population infected reaches 90,000.
Step-by-step explanation:
We can write the rate of spread of the virus as:
We know that P(0)=100 and P(3)=100+200=300.
We have to calculate t so that P(t)=0.9*100,000=90,000.
Solving the diferential equation
Then the model for the population infected at time t is:
Now, we can calculate t for P(t)=90,000
At half day of the 4th day (t=4.488), the population infected reaches 90,000.
Answer:
Mean, μ = 200
Standard deviation, σ = 10
Step-by-step explanation:
Data provided:
a) true percentage of graduates who stay at their first job less than two years
p = 50% = 0.5
q = 1 - p = 1 - 0.5 = 0.5
Number of graduates selected in a group, n = 400
Now,
The mean is calculated as:
Mean, μ = p × n
or
μ = 0.5 × 400 = 200
and,
standard deviation, σ =
or
σ =
or
σ = √100
or
σ = 10
