Complete Question
Leicester City Fanstore (LCF) will be selling the "new season jersey" for the 2018-2019 season. The regular price of the jersey is $80. Each jersey costs $40. Leftover jerseys will be sold at the end of the season (or later) at $30. Since jerseys are produced in China and lead time is long, Puma wants LCF to decide the quantity right now (December 2017).
a. After some analysis using historic data, LCF expects that the demand will follow a Normal distribution with a mean 40,000 and a standard deviation of 8,000 due to uncertainty in team performance. How many jerseys should LCF order?
b. If a customer cannot buy the jersey from LCF (in the case of a stock-out), they may leave the store disappointed and use other channels (such as Puma stores or puma.com) in future. LCF thinks that the lost customer goodwill is around $10. Should LCF change their decision in part (a)? If yes, please state the number of jerseys LCF should order.
c. Please state whether the following statement is always true, and give a brief explanation. If [tex]C_o =C_i[/tex], the news vendor solution is the mean.
Answer:
a
[tex]N = 46728[/tex]
b
[tex]n = 47728[/tex]
c
Yes it is always true
Step-by-step explanation:
From the question we are told that
The regular price of the jersey is [tex]P_r = \$ 80[/tex]
The cost of producing a jersey is [tex]C= \$ 40[/tex]
The left-over price of the jersey is [tex]P_o = $ 30[/tex]
The mean is [tex]\mu = 40000[/tex]
The standard deviation is [tex]\sigma = 8000[/tex]
The cost of lost customer goodwill is [tex]C_g = \$ 10[/tex]
Generally the fund that LCF will loss for one jersey if they order for too many jersey (i.e more than they need )is mathematically represented
[tex]C_o = P_o - C[/tex]
=> [tex]C_o = 40 - 30[/tex]
=> [tex]C_o = \$ 10[/tex]
Generally the fund that LCF will loss for one jersey if they order lesser amount jersey (i.e less than they need )is mathematically represented
[tex]C_i = P_r - C[/tex]
=> [tex]C_i = 80 - 40[/tex]
=> [tex]C_i = \$ 40[/tex]
Generally the critical ratio is mathematically represented as
[tex]Z = \frac{C_i }{ C_i + C_o}[/tex]
=> [tex]Z = \frac{40}{ 40 + 10}[/tex]
=> [tex]Z = 0.8[/tex]
Generally the critical value of [tex]Z = 0.8[/tex] to the right of the normal curve is
[tex]z = 0.841[/tex]
Generally the optimal quantity of jersey to order is mathematically represented as
[tex]N = \mu * [z * \sigma][/tex]
=> [tex]N = 40000 * [0.841 * 8000][/tex]
=> [tex]N = 46728[/tex]
Considering question b
Generally considering the factor of customer goodwill the fund that LCF will loss for one jersey if they order lesser amount jersey (i.e less than they need )is mathematically represented as
[tex]C_k = C_i + C_g[/tex]
=> [tex]C_k = 40 + 10[/tex]
=> [tex]C_k = \$ 50[/tex]
Now the critical ratio is mathematically represented as
[tex]Z = \frac{C_k }{ C_k + C_o}[/tex]
=> [tex]Z = \frac{50}{ 50 + 10}[/tex]
=> [tex]Z = 0.833[/tex]
Generally the critical value of [tex]Z = 0.833[/tex] to the right of the normal curve is
[tex]z = 0.966[/tex]
Generally the optimal quantity of jersey to order is mathematically represented as
[tex]n = \mu * [z * \sigma][/tex]
=> [tex]n = 40000 * [0.966 * 8000][/tex]
=> [tex]n = 47728[/tex]
Considering question c
When [tex]C_o =C_i[/tex] then
The critical ratio is mathematically represented as
[tex]Z = \frac{C_k }{ C_k + C_k}[/tex]
=> [tex]Z = \frac{1}{ 2}[/tex]
=> [tex]Z = 0.5[/tex]
Generally the critical value of [tex]Z = 0.5[/tex] to the right of the normal curve is
[tex]z = 0[/tex]
So
The optimal quantity of jersey to order is mathematically represented as
[tex]n = \mu * [z * \sigma][/tex]
=> [tex]n = 40000 * [0* 8000][/tex]
=> [tex]n = 40000 = \mu[/tex]
Hence the statement in c is true

IF AABD
ACBE, find the value of x.
27 cm
12 cm
SE
E
23.4 cm
Answer:
[tex] x = 10.4 [/tex]
Step-by-step explanation:
Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:
[tex] \frac{BD}{BE} = \frac{AD}{CE} [/tex]
BD = 12 cm
BE = x
AD = 27 cm
CE = 23.4 cm
Plug in the values
[tex] \frac{12}{x} = \frac{27}{23.4} [/tex]
Cross multiply
[tex] x \times 27 = 23.4 \times 12 [/tex]
[tex] 27x = 280.8 [/tex]
Divide both sides by 27
[tex] x = 10.4 [/tex]

The mean number of typhoon hitting US follows a Poisson distribution with
variance 0.5 per month. Find the probability that
(a) 4 typhoons will hit US in a year.
(b) at least 2 typhoons will hit US in a given half-year.
Answer:
A) 0.1339
B) 0.8078
Step-by-step explanation:
The Poisson Distribution formula is given by;
P(x; μ) = (e^(-μ) × (μ^(x))/x!
We are given;
Variance = 0.5 per month
Now, in Poisson distribution, variance = mean.. Thus, mean μ = 0.5 per month
A) We want to find the probability that 4 typhoons will hit US in a year.
Thus, x = 4
But since it's for a year, then μ = 0.5 × 12 = 6
So;
P(x = 4) = (e^(-6) × (6^(4))/4!
P(x = 4) = 0.00247875 × 1296/24
P(X = 4) = 0.1339
B) probability that at least 2 typhoons will hit US in a given half-year is;
P(X ≥ 2) = 1 - P(X < 2)
P(X < 2) = P(X = 0) + P(X = 1)
In a half given year, μ = 0.5 × 6 = 3
P(X = 0) = (e^(-3) × (6^(0))/0!
P(X = 0) = 0.0498
P(X = 1) = (e^(-3) × (6^(1))/1!
P(X = 1) = 0.1494
P(X < 2) = 0.0498 + 0.1494
P(X < 2) = 0.1922
P(X ≥ 2) = 1 - 0.1922
P(X ≥ 2) = 0.8078

Step-by-step explanation:
A court holds jurisdiction over five counties, and the juries are required to be made up in a representative manner from the eligible populations of these five counties. An investigator notices that the county where she lives has 14% of the total population of the five counties eligible for jury duty, yet records reveal that over the past five years only 122 out of the 1386 jurors used by the court reside in her county. Do you feel that this constitutes reasonable evidence that the jurors are not being randomly selected from the total population
Answer:
Yes.
I feel that since only about 9% of the jurors are being appointed from the county, instead of the more representative 14%, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population.
Step-by-step explanation:
a) Data and Calculations:
County population proportion = 14%
This implies that the country is supposed to have at least 1,386 * 14% = 194 of the jurors used by the court.
Evidence from records show that the county has only 122 of 1,386 = 9% (122/1,386)
This means that about 72 (194 - 122) jurors are not being appointed from the county.
And 72 represents about 5% of 1,386 (72/1,386). This number is more than half of those being appointed from the county or more than 50% or precisely 59%.
Therefore, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population. The selection is not representative of the population characteristics.

Joselyn saw an alligator that was 5 feet long. How many inches is 5 feet.
Answer:
The alligator is 60 Inches long.
Step-by-step explanation:
5 feet is 60 inches.
hope it helps!
Answer:
60 inches
Step-by-step explanation:
There are 12 inches in 1 foot, therefore the ratio of inches to feet is 12:1.
If the alligator is 5 feet than the amount of inches increase.
In order to find how long the alligator is in inches, multiply 5 by 12
5 x 12 = 60

You run around the perimeter of a baseball field at a rate of at most 12 feet per second. Which of the following are possible amounts of time that it takes you to run around the baseball field?
Answer: 79 seconds.
Step-by-step explanation:1) we have to calculate the lenght of the baseball field.
perimeter of the baseball field=2(radius)+lenght of a semicircle.
2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)
Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,
2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.
10 ft------------------------1 second
789,82 ft----------------- x
x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s

Need help with this ASAP it’s due in 10 minutes
Answer:
Step-by-step explanation:
Formula to be used,
A = [tex]P(1+\frac{r}{n})^{nt}[/tex]
Here, A = Final amount
P = Principal amount
r = rate of interest
n = Number of compounding (In a year)
t = Duration of investment (In years)
Question (5)
P = $4250
r = 0.015
n = 4
t = 3 years
A = [tex]4250(1+\frac{0.015}{4})^{4\times 3}[/tex]
A = [tex]4250(1.00375)^{12}[/tex]
A = $4445.24
Part (C)
1). P = $6000
r = 0.03
n = 2
t = 10 years
A = [tex]6000(1+\frac{0.03}{2})^{2\times 10}[/tex]
= [tex]6000(1.015)^{20}[/tex]
= $8081.13
2). P = $9000
r = 0.05
n = 2
t = 8 years
A = [tex]9000(1+\frac{0.05}{2})^{2\times 8}[/tex]
= [tex]9000(1.025)^{16}[/tex]
= $13360.55
Automobiles arrive at the drive-through window at a post office at the rate of 7 every 10 minutes. The average service time is 7 minutes. The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed. (Note: the given equations are NOT necessarily in the correct order.) What is the average time a car is in the system?Formulas for 13.17 What is the average number of cars in the system? What is the average time cars spend waiting to receive service? What is the average number of cars in line behind the customer receiving service? What is the probability that there are no cars at the window? What percentage of the time is the postal clerk busy? What is the probability that there are exactly two cars in the system?
Answer:
1) the average time a car is in the system is 0.1587 min
2) the average number of cars in the system 0.1111
3) the average time cars spend waiting to receive service is 0.01587 min
4) the average number of cars in line behind the customer receiving service is 0.01111
5) the probability that there are no cars at the window is 0.9
6) the percentage of time that the postal clerk is busy is 10%
7) the probability that there are exactly two cars in the system is 0.1217
Step-by-step explanation:
Given that;
Arrival rate λ = the rate of 7 every 10 minutes = 7/10 = 0.7
Average service time μ = 7 minutes
The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed.
1) What is the average time a car is in the system?
Average in the system W = 1 / (μ - λ)
= 1 / (7 - 0.7) = 1 / 6.3 = 0.1587 min
therefore the average time a car is in the system is 0.1587 min
2) What is the average number of cars in the system?
Average number of cars L = λ / (μ - λ)
= 0.7 / (7 - 0.7) = 0.7/6.3 = 0.1111
Therefore the average number of cars in the system 0.1111
3) What is the average time cars spend waiting to receive service?
Average time spend waiting for services Wq = λ / μ(μ - λ)
= 0.7 / 7(7 - 0.7) = 0.7/44.1 = 0.01587 min
Therefore the average time cars spend waiting to receive service is 0.01587 min
4) What is the average number of cars in line behind the customer receiving service?
average number of cars in line behind the customer receiving service
Lq = λ² / μ(μ - λ) = (0.7)² / 7(7 - 0.7) = 0.49 / 44.1 = 0.01111
Therefore the average number of cars in line behind the customer receiving service is 0.01111
5) What is the probability that there are no cars at the window?
probability that there are no cars at the window = 1 - (λ / μ)
= 1 - (0.7 / 7) = 1 - 0.1 = 0.9
Therefore the probability that there are no cars at the window is 0.9
6) What percentage of the time is the postal clerk busy?
percentage of the time is the postal clerk busy = (λ / μ)
= (0.7 / 7) = 0.1 ≈ 10%
Therefore the percentage of time that the postal clerk is busy is 10%
7) What is the probability that there are exactly two cars in the system?
the probability that there are exactly two cars in the system = (λ²e^-λ) / 2!
= (0.7²e^-0.7) / 2! = 0.2433 / 2 = 0.1217
Therefore the probability that there are exactly two cars in the system is 0.1217
