Answer:
It takes less time sending 5 letters the traditional way with a probability of 36.7%.
Step-by-step explanation:
First we must take into account that:
- The traditional method is distributed X ~ Poisson(L = 1)
- The new method is distributed X ~ Poisson(L = 5)
Where L is the intensity in which the events happen in a time unit and x is the number of events.
To solve the problem we must calculate the probability of events (to send 5 letters) in a unit of time for both methods, so:
- For the traditional method:
- For the new method:
According to this calculations we have a higher probability of sending 5 letters with the traditional method in a unit of time, that is 36.7%. Whereas sending 5 letters with the new method is less probable in a unit of time. In other words, we have more events per unit of time with the traditional method.
The cell phone tower is 1260 feet tall
<em><u>Solution:</u></em>
Given that 10-ft vertical post casts a 12-in shadow
At the same time a nearby cell phone tower casts a 126-ft shadow
To find: height of cellphone tower
We can use proportion to solve the sum
Here,
Let "x" be the height of tower
height of post = 10 feet
shadow of tower = 126 feet
shadow of post = 12 inches
We know that,
1 inches = 0.0833333 foot
12 inches = 12 x 0.0833333 foot = 1 foot
shadow of post = 1 foot
Thus the proportion becomes,
Thus the cell phone tower is 1260 feet tall
