Answer:
32.33% probability of having at least 3 erros in an hour.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
The mean number of errors is 2 per hour.
This means that 
(a) What is the probability of having at least 3 errors in an hour?
Either you have 2 or less errors in an hour, or we have at least 3 errors. The sum of the probabilities of these events is decimal 1. So

We want 
So

In which







32.33% probability of having at least 3 erros in an hour.
Function 2 has greater rate of change
Step-by-step explanation:
In order to find the rate of change we have to covert the given linear functions in slope-intercept form
<u>Function 1:</u>
<u></u>
<u></u>
Adding 2x on both sides
<u></u>
<u></u>
Dividing both sides by 5
<u></u>
<u></u>
Let m1 be rate of change of function 1:
<u></u>
<u></u>
<u></u>
<u>Function 2:</u>
<u></u>
<u></u>
Adding 6x on both sides
<u></u>
<u></u>
Dividing both sides by 3
<u></u>
<u></u>
Let m2 be the slope of function 2
<u></u>
<u></u>
As we can see that

<u></u>
Function 2 has greater rate of change

Answer:
C
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=x+1 and y=-x+2. The line y=-x+2 continues to the right and has an open circle at the end. So this point is not included. This means the interval is a greater than sign but not equal to. This means C is the answer.
Answer:
After 2 years Miguel will have in his account $541.64
Step-by-step explanation:
The formula for calculating compound interest continuously is:

Where A is the amount of money obtained after t years.
r is the compound interest rate and p is the initial amount
In this case we have that:

Then we must find the final amount A
