Answer:
what is the question
Step-by-step explanation:
Answer:
Step-by-step explanation:
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
In order to find the expected value E(1/X) we need to find this sum:

Lets consider the following series:
And let's assume that this series is a power series with b a number between (0,1). If we apply integration of this series we have this:
(a)
On the last step we assume that
and
, then the integral on the left part of equation (a) would be 1. And we have:

And for the next step we have:

And with this we have the requiered proof.
And since
we have that:

Answer:
Terrance is incorect.
Correct output coordinates (-y,-x)
Step-by-step explanation:
Let
be the input coordinates.
First translation is a rotation of 180° clockwise about the origin. This translation has a rule

Second translation is a reflection over the line y = x. The general rule for the reflection across the line y=x has the rule

When a sequence of two translations are applied to the initial input coordinates, then

As you can see Terrance made a mistake and these two transformations do not cancel themselves out.
I don't really get what the "35,000 feet university sea level" part is saying, but without it, the answer would be:
3.5 x 550 = 1,925
The plane traveled 1,925 miles.
And with it, the answer would be:
3.5 x 550 = 1,925
35,000 ft = 6.6 mi
1,925 + 6.6 = 1,931.6
The plane traveled 1,931.6 miles.
Hope this helped a little at least.
