The equation is
P = 200 / (1 + 20000 e^-0.549t)
TO get the rate of epidemic growth, we differentiate the equation with respect to t
dP/dt = -200(1 + 2000 e^-0.549t)^-2 (20000)(-0.549)
Substitute t = 10 and you will get the epidemic growth rate after 10 years
Your answer would be D) 3x + 6
This is because, when you subtract the like terms, you get x - -2x, which is 3x, and 1 - -5, which is 6.
I hope this helps!
Answer:
The probability that you would choose a green candy:
or approximately 32%.
Step-by-step explanation:
The general form of probability can be calculated as the following fraction:

First, to find the total number of outcomes, you need to add all of the candies together: 42 + 45 + 20 + 32 = 139, so there are 139 total outcomes. Since there are a total of 45 green candies, the probability of choosing green from the total can be written as:

Dividing the numerator by the denominator and multiplying by 100 gives us the percentage of approximately 32%.
