Answer:
1000 * 
Bacteria after 18 hours,
Step-by-step explanation:
The condition given in the problem is that the number of bacterial triple after every 2 hours.
So, after 2 hours, total bacteria= 1000 * 3
So, after 4 hours, total bacteria= 1000 * 3 * 3
Therefore, the general format for the number of bacteria is 1000 * 
, where n is the number of times the bacteria has tripled.
In 18 hours, there are 
ties that the bacteria has tripled.
Therefore, the no. of bacteria after 9 hours= 1000 *
Answer:
It is very likely that Rosa wins both prizes.
Step-by-step explanation:
The probability of winning a T‐shirt is 0.89 and the probability of winning a $20 gift certificate is 0.05. Which statement correctly describes the chances of Rosa winning a T‐shirt or a $20 gift certificate?
We have these three possibe outcomes.
Win t-shirt(0.89 probability) and lose the gift certiciate(1 - 0.05 = 0.95 probability)
Lose t-shirt(0.11 probability) and win the gift certiciate(0.05 probability).
Win both.
So
0.8955 = 89.55% probability of Rosa winning a T‐shirt or a $20 gift certificate, which is considered a very likely probability. So the answer is:
It is very likely that Rosa wins both prizes.
