Answer:
b
Step-by-step explanation:
<ABC refers just to angle B. Angle B is on the opposite side of 98 therefore we would have to divide it by two. 98 divided by 2 is 49
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:
five times the porduct of x minus 6
Step-by-step explanation:
Answer:
$48.0
Step-by-step explanation:
Given data
Total cost of DVDs= $24.99+ $19.99
=$44.98
Let us compute the amount of the tax 6.75%
= 6.75/100* 44.98
=0.0675* 44.98
=$3.03615
The total cost including the tax is
=44.98+3.03615
=$48.0
