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)
<h2>
6 2/3 pounds per roommate</h2>
<h3>
Step-by-step explanation:</h3>
When you have a number of food, 40, and people, 6, it's telling you to divide both numbers.
40 / 6 = 6 2/3 pounds.

Best of Luck to you!
Answer:
Average salary: 56
Standard deviation of the salary: 8
Step-by-step explanation:
$56,000 dollars is 56 thousand dollars.
$8,000 is 8 thousand dollars.
The mean is the average. So the average, measured in thousands of dollars, is 56.
The standard deviation is $8,000. So, the standard deviation measured in thousands of dollars, is 8.
