This is how to solve this
Answer:
Step-by-step explanation:
For this case we can use the moment generating function for the normal model given by:
And this function is very useful when the distribution analyzed have exponentials and we can write the generating moment function can be write like this:
And we have that the moment generating function can be write like this:
And we can write this as an infinite series like this:
And since this series converges absolutely for all the possible values of tX as converges the series e^2, we can use this to write this expression:
and we can use the property that the convergent power series can be equal only if they are equal term by term and then we have:
And then we have this:
And then we can find the
And we can find the variance like this :
And first we find:
And then the variance is given by:
Answer:
The loan amount of the tuition fee is $3285
Step-by-step explanation:
Given as :
The student's tuition fee amount = $2628
The loan amount for the fee = of the tuition fee
Let The loan amount = $ A
So, According to question
The loan amount for the fee = × tuition fee amount
A = × $2628
or, A =
Or, A = 5 × 657
∴ A = $3285
So, The loan amount = A = $3285
Hence The loan amount of the tuition fee is $3285 Answer
Answer:
domain {-1,1.3}
Step-by-step explanation:
The domain is the input values, or in this case the first or x values
domain {3,1,-1,-1}
We do not put the same value twice
domain {3,1,-1}
We like to put them in numerical order
domain {-1,1.3}
