Answer:
1.) 1 1/14
2.) 1/5
3.) 1/15
4.) 1
(They are all simplified)
Step-by-step explanation:
Add 25 to both sides:

Square root both sides.
When you square root a perfect square, you will get a plus/minus result:



The other solution to this answer is x = -5.
5 1/4? Im not sure what the question is asking but whatever
9.4/10 is the simplest form
Answer:
The probability that X is less than 32 minutes is 0.736.
Step-by-step explanation:
Given : The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift. If X has an average value of 24 minutes.
To find : What is the probability that X is less than 32 minutes?
Solution :
If X has an average value of 24 minutes.
i.e. 
The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.
The exponentially function is 
The function form according to question is

The probability that X is less than 32 minutes is



Therefore, the probability that X is less than 32 minutes is 0.736.
