Answer:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:

The best answer for this case would be:
C. Poisson distribution
Step-by-step explanation:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
And for this case we want to calculate this probability:

The best answer for this case would be:
C. Poisson distribution
Answer:
The answer is 1 cup of sugar
Step-by-step explanation:
x = 2 x 1.5/3
x = 3/3
x = 1 cup of sugar
hope it helps!
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
