Answer:
X 1 2 3 4 5 6
P(X) 0.115 a 0.422 0.312 0.034 0.015
If we want a probability distribution we need to satisfy two important conditions:
1)
2)
And using the second condition we have this:
With a the probability associated with the value of X=2 and solving for a we got:
So then for this case
Step-by-step explanation:
Let X the random variable that represent the number of classes that a student takes
For this case we have the following probability distribution given:
X 1 2 3 4 5 6
P(X) 0.115 a 0.422 0.312 0.034 0.015

Answer:
5
Step-by-step explanation:
3 is half of 6, so since half of 10 is 5 I'd say 5.
I hope this helped <3
Answer:
The answer is C
Step-by-step explanation:
cedar is 68 square root is 8.2
Pine is 7.92
walnut is 63/8=7.89
oak is 7.3
Answer:
It's pretty simple when you know math the correct way. Here.
Step-by-step explanation:
$1,685 - $792 = $893
Not sure about this? Do it a different way! Use the answer in a equation!
$893 + $792 = $1,685
