Answer:
$48,739.50
Step-by-step explanation:
You are going to want to use the simple interest formula for this.
<em>P = principal amount
</em>
<em>r = interest rate (decimal form)
</em>
<em>t = time (years)</em>
<em />
First convert 4.5% into its decimal form:
4.5% -> -> 0.045
Next, we need to change 120 months into years:
<em>(10 years)</em>
<em />
Now, plug in the values into the equation:
The interest earned after 120 months was $48,739.50

Answer:
0.9999985 = 99.99985% probability that in a day, there will be at least 1 birth.
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 interval.
Assume that the mean number of births per day at this hospital is 13.4224.
This means that
Find the probability that in a day, there will be at least 1 birth.
This is:
In which
Then
0.9999985 = 99.99985% probability that in a day, there will be at least 1 birth.
Using the PEMDAS method will allow you to solve the expression. First, (-10)-(-11)= 1. Then you would subtract the -10 which would give you -9 as your full answer!
