Answer:

450 Bacteria

Step-by-step explanation:

First we need to consider the amount of bacteria that grew after two hours. Since 100 bacteria grew after 2 hours, we need to find how much bacteria grows per hour.

We can find that by dividing 100 by 2

100/2 = 50 Bacteria per hour

Now that we know how much bacteria grows per hour, we can then multiply that amount to the amount of hours asked in the problem.

9 hours x 50 Bacteria = 450 Bacteria in 9 hours.

You and a friend are rolling two 6-sided number cubes and placing bets on the sum of the outcome. is it better to place a bet on
Zina [86]
To solve for this, we need to figure out the sum of any two numbers on the dice that will become a pair factor for the listed answers.
What I mean by that is that we need to find the probability between how many two numbers will sum up to the answer.

3 can be 1 + 2, that's it. 3 has a probability of (1).
4 has a sum of 1 + 3, and 2 + 2, that's it. 4 has a probability of (2).
7 has a sum of 1 + 6, 2 + 5, and 3 + 4. 7 has a probability of (3).
11 has a sum of 5 + 6, that's it. 11 has a probability of (1).

The numbers in parenthesis are the probabilities.
7 has the highest number, so 7 has the highest probability.

Your answer is: 7.

I hope this helps!
