Answer:

And we can use the probability mass function and we got:
And replacing we got:

Step-by-step explanation:
Let X the random variable of interest "number of graduates who enroll in college", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:

And we can use the complement rule and we got:

And we can use the probability mass function and we got:
And replacing we got:

Answer:
- 300 feet or 300 feet below sea level
Step-by-step explanation:
Starting elevation of diver = 0 feet
decrease of elevation in 1 minute = 60 feet
decrease of elevation in 1* 5 minute = 60*5 feet = 300 feet
therefore
in five minutes diver loses 300 feet elevation
Elevation of diver after 5 minute = Starting elevation of diver - value of decrease of elevation of diver in five minutes
Elevation of diver after 5 minute = 0 feet - 300 feet = - 300 feet.
Therefore Elevation of diver after 5 minute is - 300 feet
i.e 300 feet below sea level as sea level elevation is taken as standard value of elevation of 0 feet.
Answer: A
Step-by-step explanation: The square root of 9 is 9.7 so it would be between 5 and 10
