Question

This strain also started with a genetic mutation in patient zero that caused them to turn into a zombie. Zombies infected with strain B can infect 1 person every minute. All zombies with strain B can infect new people at the same rate.
Using the CDC Virus Information, complete the table below for STRAIN B to show the number of zombies after each minute.
Strain B started with a genetic mutation in patient zero that caused them to turn into a zombie. This strain differs from A in that all zombies can infect new people. Zombies infected with strain B can infect 1 person every minute.

minutes: 0,1,2,3,4,5,6,7,8,9,10
number of zombies: 1,_,_,_,_,_,_,_,_,_

Answer 1

To complete the table for Strain B, we can analyze how the number of zombies grows over time based on the infection rate of 1 additional zombie per minute per existing zombie.

Here's how the number of zombies increases:

- **Minute 0**: Start with 1 zombie (Patient Zero).
- **Minute 1**: The original zombie infects 1 additional person, so there are now 2 zombies.
- **Minute 2**: The 1 original zombie and the 1 newly infected zombie each infect 1 more person, making it 4 zombies total (2 + 2).
- **Minute 3**: The 4 zombies can each infect 1 more person, resulting in 8 zombies (4 + 4).
- **Minute 4**: The 8 zombies can each infect 1 more person, resulting in 16 zombies (8 + 8).
- **Minute 5**: The 16 zombies can each infect 1 more person, resulting in 32 zombies (16 + 16).
- **Minute 6**: The 32 zombies can each infect 1 more person, resulting in 64 zombies (32 + 32).
- **Minute 7**: The 64 zombies can each infect 1 more person, resulting in 128 zombies (64 + 64).
- **Minute 8**: The 128 zombies can each infect 1 more person, resulting in 256 zombies (128 + 128).
- **Minute 9**: The 256 zombies can each infect 1 more person, resulting in 512 zombies (256 + 256).
- **Minute 10**: The 512 zombies can each infect 1 more person, resulting in 1024 zombies (512 + 512).

Now, let's fill in the table:

| Minutes | Number of Zombies |
|---------|-------------------|
| 0 | 1 |
| 1 | 2 |
| 2 | 4 |
| 3 | 8 |
| 4 | 16 |
| 5 | 32 |
| 6 | 64 |
| 7 | 128 |
| 8 | 256 |
| 9 | 512 |
| 10 | 1024 |

So, based on these calculations, the completed table for Strain B is as shown above.
