Answer:
Step-by-step explanation:
Step 1: First apply radical rule in the given expression.
Here,
The expression becomes
Step 2: Now, apply exponent rule in the above expression
So, the expression becomes, .
Step 3: Take cross multiply the denominator and numerator of the fraction in the power of 7.
The answer is .
Hence the simplified form of .
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:
I think it would be 1.7
i added 1/3 and 1/2 then multiplied by 2
i think thats the right answer ...if not sorry
Let
<u>Find the sum of the mixed numbers x and y</u>
therefore
