a regional director responsible for business development in the state of pennsylvania is concerned about the number of small business failures. if the mean number of small business failures per month is 14, what is the probability that exactly 5 small businesses will fail during a given month? assume that the probability of a failure is the same for any two months and that the occurrence or non occurrence of a failure in any month is independent of failures in any other month. (round your answer to four decimal places.) g
The probability that exactly 5 small businesses will fail during a given month 0.0037268.
The Poisson distribution would be used to calculate the likelihood that different counts of the same event will occur within a constrained time period. It is viewed as a discrete distribution since it evaluates counts. The distribution displays identical mean and dispersion values.
The pmf of the Poisson distribution is
[tex]p(x)=\frac{e^{\lambda} \lambda^{x}}{x!}[/tex]
The mean total number of small business failures λ=14
Let x represent the number of failed small businesses in a given month.
X~P(14)
X follows the Poisson distribution since the likelihood of failure stays constant for two months and the mean number of failures per month is 14.
The likelihood that precisely four small firms would fail in a given month must be calculated.
P(X=5)
[tex]P(X=5)= \frac{e^{14} \ 14^{5}}{5!}[/tex]
P(X=5)= 0.44721/5!
P(X=5)=0.0037268.
In a month there is 0.0037 that is 3.7% probability that a small business fail.

Helen thinks of two numbers. The highest common factor of her two numbers is 5. The lowest common multiple of her two numbers is a multiple of 12. Write down two possible numbers that Helen could be thinking of.
It is evident from the steps above that it is impossible to be have two numbers with the same LCM and HCF as 12 and 5, respectively.
Explain the term LCM and HCF?The entire form of the Least Common Multiple in mathematics is LCM, whereas the official name of the Highest Common Factor is HCF. The L.C.M. indicates the least number that is precisely divisible by 2 or more numbers, while the H.C.F. describes the biggest factor existing between any given pair of 2 or more numbers.The given condition are-
Helen considers two numbers that fit the following criteria:
Five is the two integers' largest common factor.Twelve is the least frequent multiple of a two numbers.The steps to solve the condition are-
1. It is assumed that when Helen considers of two numbers, they have corresponding HCF and LCM values of 5 and 12.
2. A smallest common multiple shared by two numbers is referred to as the least common number.
LCM of 4 with 6 is 12, for instance.
3. The highest number which divides the two selected numbers, leaving a residue of 0, is referred to as the highest common factor.
HCF of 6 and 8 is 2, for instance.
4. Given that the LCM of Helen's two chosen numbers is 12, even multiples of 12 are indeed the two numbers' common multiples. In light of this, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, and so forth.
5. The only numbers that may be divided by 5 are 60 and 120. All other numbers have HCF values apart from 5. 60 and 120 have an HCF of 60, but not 5.
6. As a result, it is evident from the steps above that it is impossible to be have two numbers with the same LCM and HCF as 12 and 5, respectively.
Therefore, the aforementioned criteria cannot exist mathematically.

0.3108 is the probability that a single tire randomly selected from the population will have a lifetime between 46,800 and 49,200 miles
What is probability?Probability is a mathematical discipline that concerns with numerical figures of how probable an occurrence is to occur or how probably a statement is to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
X ~ N ( µ = 48000 , σ = 3000 )
As we know, P ( 46800 < X < 49200 )
Standardizing the value, we get -
Z = ( X - µ ) / σ
Z = ( 46800 - 48000 ) / 3000
Z = -0.4
Z = ( 49200 - 48000 ) / 3000
Z = 0.4
Also,
P ( -0.4 < Z < 0.4 )
P ( 46800 < X < 49200 ) = P ( Z < 0.4 ) - P ( Z < -0.4 )
P ( 46800 < X < 49200 ) = 0.6554 - 0.3446 (Probability calculated from Z table)
P ( 46800 < X < 49200 ) = 0.3108

a trucker driver can expect to make $us55,065 per year in the us. assuming that this driver works 70 hours per week and 52 weeks per year, what is the equivalent salary in canadian dollars per hour?
The equivalent salary in Canadian dollars per hour of the driver is $28.13/hour.
To convert the annual salary of a truck driver in the US from US dollars to Canadian dollars, you can use the current exchange rate between the two currencies. The exchange rate fluctuates constantly, so you will need to use the most current rate.
Assuming the current exchange rate is 1 US dollar to 1.26 Canadian dollars, the annual salary of a truck driver in the US, $55,065, is equivalent to 71,040.90 Canadian dollars. If the truck driver works 70 hours per week and 52 weeks per year, their hourly wage in Canadian dollars would be $28.13.
Here's the calculation:
Annual salary in Canadian dollars = $55,065 * 1.26 = $71,040.90
Hourly wage in Canadian dollars = $71,040.90 / (70 hours/week * 52 weeks/year) = $28.13/hour
Keep in mind that this is just a rough estimate, as the exchange rate can change over time, and the actual wage may vary depending on the driver's experience, location, and other factors.
So, the equivalent salary in Canadian dollars per hour of the driver is $28.13/hour.

What is probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
Here,
In this case, let G represent the state of guilt and H represent the state of innocence.
and Let K stand for the situation where the truth serum shows that someone is guilty.
We are aware that 90% of the guilty suspects receive just verdicts, i.e. P(K|G)=0.9.
Additionally, we know that innocent suspects are mistakenly identified 1% of the time, or P(K|H)=0.01.
When a suspect is chosen from a group of suspects, of whom 5% committed a crime, and the serum suggests that the suspect is guilty, we must determine the likelihood that the suspect is innocent.
We must therefore determine the probability P(H|K).
A group of people was chosen for the suspect, of which 5% were criminals.
so the probability that selected person is guilty is
P(G) = 0.05
Therefore, the probability that selected person is not guilty is
P(H) = 1 – P(G) = 1 – 0.05 = 0.95
Then,
Using Bayes' Theorem, we get
P(H|K) =[tex]\frac{P(H)P(K|H)}{P(H)P(K|H) + P(G)P(K|G)}[/tex]
= [tex]\frac{0.95*0.01}{0.95*0.01 + 0.05*0.9}[/tex] =0.1743

The reqiured two digit number is 54
Let, a two-digit number be n
the digit at tens place as x and the digit at unit place be y
The tens digit of a two-digit number exceeds the units digit by 1.
x = y + 1 .............(1)
if the number is divided by the sum of its digits, the quotient is 6.
(10x + y)/(x + y) = 6
Substitute above value of x in this equation.
(10(y + 1) + y) = 6(y + 1 + y)
10y + 10 + y = 6(2y + 1)
11y + 10 = 12y + 6
y = 4
Substitute above value of y in equation (1),
x = 4 + 1
x = 5
