Amedical researcher is studying the spread of a virus in a population of 1000 laboratory mice. during any week, there is a 90% probability that an infected mouse will overcome the virus, and during the same week there is a 30% probability that a noninfected mouse will become infected. one hundred mice are currently infected with the virus.

how many will be infected next week and in 2 weeks?

(a) next week

mice

(b) in 2 weeks

mice

a) 280

b) 244

Step-by-step explanation:

a)

One hundred mice are currently infected with the virus and 900 are okay, so next week we should have 30% of 900 = 270 new infected mice and 90% of 100 = 90 recovered mice for a total of 370 - 90 = 280 infected mice.

b)

The following week we should have 30% of 1000 - 280 = 30% of 720 = 216 new infected mice and 90% of 280 = 252 recovered mice for a total of 280 + 216 - 252 = 244 infected mice.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
