The answer would be -22g-12
Answer:
a)
And we can find the individual probabilities like this:
And replacing we got:
b)
Step-by-step explanation:
Let X the random variable that represent the number of hurricanes hitting the coast of Florida annualle. We know that
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
Part a
For this case we want this probability:
And for this case we can use the complement rule like this:
And we can find the individual probabilities like this:
And replacing we got:
Part b
Using the probability mass function we have:
Answer:
65
Step-by-step explanation:
You find the one equally in the center of the numbers after they are in order.
Answer:
50
Step-by-step explanation:
im not that sure sorry
Answer: 40.45 or B
Step-by-step explanation:
63 x 0.6(100%-40%) = 37.8
37.8 x 1.07 = 40.446
40.446 rounded is
40.45
