Answer:
400,000 bacteria
Step-by-step explanation:
If we start at 100,000 and double every three hours until 6 hours, to colony will be at 400,000 bacteria. 
First find out how many times it will double by dividing 6/3=2. It will double twice in 6 hours. Next double 100,000 once, to get 200,000. Then, double it once more to get to the final answer of 400,000 bacteria.
Hope this helps!
 
        
             
        
        
        
Answer:
The probability is    ≅
 ≅ 
Step-by-step explanation:
Let's analyze the question.
There are 15 students in the 8th grade.
The students are randomly placed into three different algebra classes of 5 students each. 
We are looking for the probability that Trevor, Terry and Evan will be in the same algebra class.
One possible way to solve this question is to think about the product probability rule.
We can use it because we are in an equiprobable space. (And  also the events are independent). 
Let's set for example a class for Evan.
The probability that Evan will be in a class is 
Then for Terry there are  places out of
 places out of  that puts Terry in the Evan's class.
 that puts Terry in the Evan's class.
We write 
Finally for Trevor there are  places out of the remaining
 places out of the remaining  that puts Trevor in the same class with Evan and Terry.
 that puts Trevor in the same class with Evan and Terry.
Using the product rule we write :

The probability of the event is  ≅
 ≅ 
 
        
             
        
        
        
Answer: 24
Yes (x-2) is a factor. There is a remainder.
Step-by-step explanation:
