A study of the checkout lines at the Safeway Supermarket in the South Strand area revealed that between 4 and 7 P.M. on weekdays there is an average of four customers waiting in line. What is the probability that you visit Safeway today during this period and find?
a. No customers are waiting?
b. Four customers are waiting?
c. Four or fewer are waiting?
d. Four or more are waiting?

Answers

Answer:

(a) The probability of no customers are waiting in a line is 0.01832.

(b) The probability of 4 customers are waiting in a line is 0.19537.

(c) The probability of 4 or fewer customers are waiting in a line is 0.62885.

(d) The probability of 4 or more customers are waiting in a line during the visit is 0.56652.

Step-by-step explanation:

The number of customers waiting in a line between 4 PM and 7 PM (X) follows a Poisson distribution with parameter λ = 4.

The probability mass function of a Poisson distribution is:

[tex]P(X=x)=\frac{e^{-4}(4)^{x}}{x!} ;\ x=0, 1, 2,...[/tex]

(a)

Compute the probability that no customers are waiting in a line during the visit as follows:

[tex]P(X=0)=\frac{e^{-4}(4)^{0}}{0!}=\frac{0.01832\times1}{1}=0.01832[/tex]

Thus, the probability of no customers are waiting in a line is 0.01832.

(b)

Compute the probability that 4 customers are waiting in a line during the visit as follows:

[tex]P(X=4)=\frac{e^{-4}(4)^{4}}{4!}=\frac{0.01832\times256}{24}=0.19537[/tex]

Thus, the probability of 4 customers are waiting in a line is 0.19537.

(c)

Compute the probability that 4 or fewer customers are waiting in a line during the visit as follows:

P (X ≤ 4) = P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3) + P (X = 4)

             [tex]=\frac{e^{-4}(4)^{0}}{0!}+\frac{e^{-4}(4)^{1}}{1!}+\frac{e^{-4}(4)^{2}}{2!}+\frac{e^{-4}(4)^{3}}{3!}+\frac{e^{-4}(4)^{3}}{3!}+\frac{e^{-4}(4)^{4}}{4!}\\=0.01832+0.07326+0.14653+0.19537+0.19537\\=0.62885[/tex]

Thus, the probability of 4 or fewer customers are waiting in a line is 0.62885.

(d)

Compute the probability of 4 or more customers are waiting in a line during the visit as follows:

P (X ≥ 4) = 1 - P (X < 4)

              = 1 - P (X = 0) - P (X = 1) - P (X = 2) - P (X = 3)

              [tex]=1-\frac{e^{-4}(4)^{0}}{0!}+\frac{e^{-4}(4)^{1}}{1!}+\frac{e^{-4}(4)^{2}}{2!}+\frac{e^{-4}(4)^{3}}{3!}+\frac{e^{-4}(4)^{3}}{3!}\\=1-0.01832-0.07326-0.14653-0.19537\\=0.56652[/tex]

Thus, the probability of 4 or more customers are waiting in a line during the visit is 0.56652.

a group of 8 people went to the movies. tickets are $6 each for adults and $3 each for kids. together they pay $33 for the tickets. there are _______ adults in that group and _______ kids. can someone explain how to solve this in words for an essay.

Answers

Number of kids is 5 and number of adults is 3.

Step-by-step explanation:

Step 1: Let the number of adults be x. Then the number of kids is (8-x). Cost of tickets for adults = 6x

       Cost of tickets for kids = 3(8-x) = 24 - 3x

       Total cost = 33 = 6x + 24 - 3x = 3x + 24

⇒ 3x = 9

x = 3

⇒ 8 - x = 8 - 3 = 5

∴ Number of kids is 5 and number of adults is 3.

Final answer:

To solve this problem, you can use a system of equations. The group consists of 3 adults and 5 kids.

Explanation:

To solve this problem, we can use a system of equations. Let's represent the number of adults as 'A' and the number of kids as 'K'. We know that there are 8 people in total, so we have the equation A + K = 8. We also know that the cost of tickets for adults is $6 and for kids is $3, and they paid a total of $33. This gives us the equation 6A + 3K = 33.

We can solve this system of equations by substitution or elimination. For simplicity, let's use substitution. From the first equation, we can rewrite K as K = 8 - A. Substituting this into the second equation, we get 6A + 3(8 - A) = 33.

Simplifying the equation, we get 6A + 24 - 3A = 33. Combining like terms, we have 3A + 24 = 33. Subtracting 24 from both sides, we get 3A = 9. Dividing both sides by 3, we find A = 3.

Now that we know there are 3 adults, we can plug this into the first equation to find K. A + K = 8, so 3 + K = 8. Subtracting 3 from both sides, we get K = 5. Therefore, there are 3 adults and 5 kids in the group.

In the cafeteria 100 milk cartons were put out for breakfast. After breakfast there were 40 milk cartons left. What is the ratio of milk cartons left over to milk cartons taken?

Answers

Final answer:

The ratio of milk cartons left over to milk cartons taken from the 100 initially provided in the cafeteria is 2:3.

Explanation:

The number of milk cartons put out for breakfast in the cafeteria was 100 and after breakfast, there were 40 milk cartons left. This means that the number of milk cartons taken at breakfast is 100 - 40, which is 60. Thus, the ratio of milk cartons left over to milk cartons taken is 40:60.

We can simplify this ratio by finding the greatest common divisor (GCD) of both numbers. In this case, the GCD of 40 and 60 is 20, so by dividing both numbers by 20, we get a simplified ratio of 2:3. Therefore, the ratio of milk cartons left over to milk cartons taken is 2:3.

8) The formula for determining the area of a trapezoid is expressed as

Area = 1/2(a + b)h

Where

a and b are the length of the bases

h is the height. Therefore

The perimeter of a square must be greater than 148 inches but less than 196 inches. Find the range of possible side lengths that satisfy these conditions. (Hint: The perimeter of a square is given by P=4s, where s represents the length of a side).

Answers

Final answer:

The possible range for the side length of the square is that it is greater than 37 inches, but less than 49 inches.

Explanation:

The perimeter of a square is given by the formula P=4s, where s is the length of one side of the square. Since we know the perimeter must be greater than 148 and less than 196 inches, we can create inequality equations to solve for the side lengths, s.

Given the lowest limit, 148 < 4s. Divide both sides by 4, we get 37 < s.

 

Given the highest limit, 4s < 196. Again, divide both sides by 4, we get s < 49.

So, we conclude that the length of a side, s, must be less than 49 inches but greater than 37 inches to meet the required conditions of the question.

c. What is the probability at least one of the stocks appreciates?

Answers

Answer:

(a) 0.42

(b) 0.28

(c) 0.88

Step-by-step explanation:

Let probability that the bank stock will appreciate over a year, P(A) = 0.70

Probability that the electric utility will increase over the same period, P(B) = 0.60

Also, it is given that the two events are independent.

(a) Probability that both stocks appreciate during the period = Bank stock will appreciate * Electric utility will appreciate = P(A) * P(B)

     = 0.70 * 0.60 = 0.42 .

(b) Probability that the bank stock appreciates but the utility does not is given by;

     P(A) * (1 - P(B)) = 0.70 * (1 - 0.60) = 0.70 * 0.40 = 0.28 .

(c) Probability that at least one of the stocks appreciates = P(A [tex]\bigcup[/tex] B)

    P(A [tex]\bigcup[/tex] B) = P(A) + P(B) - P(A [tex]\bigcap[/tex] B)

In order to calculate the electric field at location A = < 0.7, 0, 0 > m, we divide the rod into 8 pieces, and approximate each piece as a point charge located at the center of the piece. 1. What is the length of one of these pieces? 2. What is the location of the center of piece number 2? 3. How much charge is on piece number 2?

Answers

Answer:

a) I = 0.1875 m

b) r_2 = 0.46875 m

c) q = -1.125*10^-8 C

Step-by-step explanation:

Given:

- The total Length of rod L = 1.5 m

- The total charge of the rod Q = -9 * 10^8 C

- Total section of a rod n = 8

Find:

1. What is the length of one of these pieces?

2. What is the location of the center of piece number 2?

3. How much charge is on piece number 2?

Solution:

- The entire rod is divided into 8 pieces, so the length of each piece would be:

                                      l = L / n

                                      l = 1.5 / 8

                                      I = 0.1875 m

- The distance from center of entire rod and center of section 2 is 2.5 times the section length

                                      r_2 = 2.5*l

                                      r_2 = 2.5*(0.1875)

                                      r_2 = 0.46875 m

- Assuming the charge on the rod is uniformly distributed. The the charge for each section of rod is given by q:

                                      q = Q / n

                                      q = -9 * 10^8 / 8

                                      q = -1.125*10^-8 C

Answers

Answer: it will take both of them 2.4 hours to complete the job.

Step-by-step explanation:

Person A can complete a job in 6 hours. This means that the rate at which Person A can complete the job per hour is 1/6

Person B can complete the same job in 4 hours. This means that the rate at which Person A can complete the job per hour is 1/4

If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be

1/6 + 1/4 = 5/12

Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,

5/12 = 1/t

t = 12/5

t = 2.4 hours

Answers

Answer:

The correct answer are 28 and 32.

Step-by-step explanation:

Given p: A number is greater than 25, that is, the possible numbers are 26, 27, 28, 29, 30, 31, 32, 33, 34, .... and so on. And

q: A number is less than 35, that is the possible numbers are 34, 33, 32, 31, 30, 29, 28, 27, 26, .... and so on.

Now, p ∧ q is true when both p and q are true, this means that we have to find numbers that follow the criterion of both p and q.

So, p ∧ q = {26, 27, 28, 29, 30, 31, 32, 33, 34}. Therefore, the correct answers are 28 and 32.

In a large corporate computer network, user log-ons to the system can be modeled as a Poisson RV with a mean of 25 log-ons per hour. (20pts) (a) What is the probability that there are no logons in an interval of 6 minutes? (b) What is the probability that the distance between two log-ons be more than one hour?

Answers

Answer:

F(t<0.1 ) = 0.91791

Step-by-step explanation:

Solution:

- Let X be an exponential RV denoting time t in hours from start of interval to until first log-on that arises from Poisson process with the rate λ = 25 log-ons/hr. Its cumulative density function is given by:

                               F(t) = 1 - e ^ ( - 25*t )                    t > 0

A) In this case we are interested in the probability that it takes t = 6/60 = 0.1 hrs until the first log-on. F ( t < 0.1 hr ), we have:

                            F(t<0.1 ) = 1 - e ^ ( - 25*0.1 )

                            F(t<0.1 ) = 0.91791

Final answer:

The probabilities of events in a Poisson process can be calculated using the Poisson distribution for a given number of events in a specific time frame and the exponential distribution for the time between events.

Explanation:

The probability of events occurring in a fixed interval of time in a Poisson process can be calculated using the Poisson distribution formula:

P(X = k) = (e-\(\lambda\)\(\lambda\)k)/k!, where \(\lambda\) is the average number of events per interval, and k is the number of events for which we want to find the probability.

For part a), we need to find the probability of no log-ons in an interval of 6 minutes. With a mean of 25 log-ons per hour, 6 minutes corresponds to \(\lambda\) = (25/60)*6. We calculate the probability for k = 0 using the Poisson Distribution.

For part b), the time between two log-ons follows an exponential distribution, which is continuous and has the probability density function f(x) = \(\lambda\)e-\(\lambda\)x. The probability that the time between two log-ons is more than one hour can be found using the complement of the cumulative distribution function for the exponential distribution.

In summary, by calculating the probabilities for part a) and b), we can use the characteristics of the Poisson and exponential distributions to find the desired probabilities.

The baseball infield at the right has an area of 90^2 square feet .what is the area of the infield?

Answers

Given below are the formulas that can be used in this question (as there is no image).

Step-by-step explanation:

If the given baseball field is in the rectangle shape.

Then area of the field is :   Side x Side

Let us assume the side of the field  = k feet

So, the area of the filed      = k   x    k

⇒ 90 =  k²

⇒ k = 9.486 feet

If the baseball field is in rectangle shape. then the area of the field is

⇒ Area = Length x Breadth

 ⇒ 90 = L x B

So the blabbering above me is completely wrong and makes no sense whatsoever.

Each month, Miss Patrick spends $60 on transportation to work, and earns $24.50 per hour.Each month, Mr. Shah spends $150 on lab equipment and earns $32.50 per month. How many hours do they have to work during the same amount

Answers

Answer:

3 hours for miss patrick 5 hours for mr shah

Step-by-step explanation:

Answer: they have to work for 11.25 hours.

Step-by-step explanation:

Let x represent the number of months for which they have to work to make the same amount.

Each month, Miss Patrick spends $60 on transportation to work, and earns $24.50 per hour. This means that if she works for x hours in a month, the total amount that she would have is

24.5x - 60

Each month, Mr. Shah spends $150 on lab equipment and earns $32.50 per month. This means that if he works for x hours in a month, the total amount that he would have is

32.5x - 150

For them to have the same amount, the number of months would be

32.5x - 150 = 24.5x - 60

32.5x - 24.5x = - 60 + 150

8x = 90

x = 90/8

x = 11.25 hours

The voltage across the capacitor increases as a function of time when an uncharged capacitor is placed in a single loop with a resistor and a battery.

1. Exponential2. Linear 3. Quadratic 4. Power

Answers

Answer:

  1. Exponential

Step-by-step explanation:

The problem statement is insufficient to describe the behavior.

_____

The capacitor's voltage is described by a differential equation such that its rate of change is proportional to the difference of the battery voltage and the capacitor voltage. The solution to the differential equation is a function that is exponential with time.

The formula V =s3 where s repesents the lengthe of an edge can be use to find the value of a cud . What is the volume of a cud that has edges of 12 inch .

Answers

Answer:

1728 cubic inches

Step-by-step explanation:

Given that the formula

[tex]V=s^3[/tex],

where s represents the length of an edge that can be used to find the value of a cud.

Given that a cud has edge as 12 inches

Using the above formula we can find volume by substituting for s.

Here we substitute s =12 inches so that we get volume in cubic inches

Volume of the cud = [tex]12^3\\=12*12*12\\\\=1728[/tex]

1728 cubic inches

Aldo took out a loan for $2500 and was charged simple interest at an annual rate of 9.3%. The total interest he paid on the loan was $186. How long was the loan for, in days? Assume that there are 365 days in a year, and do not round any intermediate computations.

Answers

Answer: 291.6 days

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

Considering Henry's loan,

P = 2500

R = 9.3%

I = 186

186 = (2500 × 9.3 × T)/100

186 = 232.5 T

T = 186/231.6

T = 0.8 years

Assume that there are 365 days in a year, it would be

0.8 × 3645 = 291.6 days
