Answer:

Step-by-step explanation:
- The probability distribution provides the probabilities of occurrence of different possible outcomes, in this case we want to know what is the probability that the variable X takes any value between 9 and 18.
- The probability of occurrence is shown in the vertical axis of the graph. We want to know what is the probability of finding values of X between 9 and 18, then we should add up the probabilities between these two values , which means adding

Answer: 5489
Step-by-step explanation:
Given the following :
Growth rate (r) = 19% per hour
Sample culture in population = 2300
Size of sample after 5 hours =?
Using the exponential relation:
P = Po * r^t
P = population after 5 hours
Po = Initial sample population
t = time
P = 2300 * (1 +19%)^t
P = 2300 ×(1 + 0.19) ^5
P = 2300 * 1.19^5
P = 2300 * 2.3863536599
P = 5488.61341777
P = 5489 (nearest integer)
