Answer:
x(t) = 2000 - e^(-k*t)
Step-by-step explanation:
Interpretation:
No . infected student = x
Total student = 2000
rate of infected students = dx / dt
not-infected student = 200 - x
The general rate at which student are infected can be expressed as below:
dx / dt = k * ( 2000 - x )
To develop an expression of x(t) we integrate the above expression by separating variables:
dx / (2000 - x ) = k * dt
Now integrate:

@ t = 0 , infected students x = 0
Hence,
C = - ln (2000)

It represents -2,but it's not exactly proven to be right
Answer:
n=10
p=0.5
k=5
Step-by-step explanation:
n represents = number of trials
p represents = probability of success
k represents = number of successes
I believe that x = 2 and y = -2
