If a project is handed in late you receive 8/9 of your earned points. You received 72 points on your late project. How many points did you lose

Answers

Final answer:

In this situation, because the project was handed in late, you lost a total of 9 points. The full score was 81, and you got 72 after a deduction.

Explanation:

The principal in this problem is understanding proportion. Given that handing in a project late results in receiving 8/9, or approximately 88.88%, of the total points, we'll figure out the total possible score by dividing the received points (72) by the portion of the full score you got for handing in the project late, which is 8/9. So, 72 ÷ 8/9 = 81. This would be the original points you could have received. You can then subtract the received points (72) from the original points (81) to ascertain the number of points lost. Therefore, 81 - 72 = 9. Consequently, you lost 9 points because the project was handed in late.

During the summer months, the prices of nonsmoking rooms with a king-sized bed in hotels in a certain area are roughly normally distributed with a mean of $131.80 and a standard deviation of $29.12. a travel agent randomly selects prices of nonsmoking rooms with a king-sized bed from 15 hotels in the area. what is the probability that their average cost will be more than $150

Answers

the probability that the average cost of nonsmoking rooms with a king-sized bed from 15 hotels in the area will be more than $150 is approximately 0.0081, or 0.81%.

To find the probability that the average cost of nonsmoking rooms with a king-sized bed from 15 hotels will be more than $150, we can use the Central Limit Theorem. Here's how:

1. Calculate the standard error of the mean (SEM) which is the standard deviation of the sample mean:

SEM = standard deviation / sqrt(sample size)

SEM = $29.12 / sqrt(15) ≈ $7.52

2. Calculate the z-score for a mean of $150:

z = (sample mean - population mean) / SEM

z = ($150 - $131.80) / $7.52 ≈ 2.41

3. Look up the z-score in the standard normal distribution table to find the probability associated with this z-score. The area to the right of a z-score of 2.41 gives us the probability that the average cost will be more than $150.

4. From the standard normal distribution table, a z-score of 2.41 corresponds to a probability of approximately 0.0081.

Therefore, the probability that the average cost of nonsmoking rooms with a king-sized bed from 15 hotels in the area will be more than $150 is approximately 0.0081, or 0.81%.

Hello! So to solve this problem, we need to divide fractions. Convert the mixed numbers into improper fractions by multiplying the denominator by whole number and adding the numerator. The rule for dividing fractions is keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over. The problem will now look like this: 63/4 * 5/12. Multiply straight across. n * n / d * d. When you do that, you get 315/48 or 6 9/16 in mixed number form. There are 6 9/16 servings, which is enough to serve approx. 7 bowls if you don't mind having a partial servings. Otherwise, only 6 bowls will get all of the 2 2/5 ounces of cereal.

Medical researcher estimates that .00004 of the population has a rare blood disorder. if the researcher randomly selects 100,000 people from the population? appendix a statistical tables (round your answers to 4 decimal places.)
a. what is the probability that seven or more people will have the rare blood disorder?

Answers

To solve this problem, we make use of the binomial probability equation.

P = [n! / (n – r)! r!] p^r * q^(n – r)

 

where,

n is the total number of sample = 100,000

r is the number of people with rare blood disorder = 7 or more

p is success of having a disorder = 0.00004

q is 1- p = 0.99996

 

But since it is easier to solve for the sum of probabilities with 0 to 6 disorder then deduct it from 1.

So,

 

=> at r = 0

P (r = 0) = [100,000! / (100,000 – 0)! 0!] (0.00004)^0 * (0.99996)^(100,000 – 0)

P (r = 0) = 0.01831

 

=> at r = 1

P (r = 1) = [100,000! / (100,000 – 1)! 1!] (0.00004)^1 * (0.99996)^(100,000 – 1)

P (r = 1) = 0.07326

 

=> at r = 2

P (r = 2) = [100,000! / (100,000 – 2)! 2!] (0.00004)^2 * (0.99996)^(100,000 – 2)

P (r = 2) = 0.14652

 

=> at r = 3

P (r = 3) = [100,000! / (100,000 – 3)! 3!] (0.00004)^3 * (0.99996)^(100,000 – 3)

P (r = 3) = 0.19537

 

=> at r = 4

P (r = 4) = [100,000! / (100,000 – 4)! 4!] (0.00004)^4 * (0.99996)^(100,000 – 4)

P (r = 4) = 0.19537

 

=> at r = 5

P (r = 5) = [100,000! / (100,000 – 5)! 5!] (0.00004)^5 * (0.99996)^(100,000 – 5)

P (r = 5) = 0.15630

 

=> at r = 6

P (r = 6) = [100,000! / (100,000 – 6)! 6!] (0.00004)^6 * (0.99996)^(100,000 – 6)

P (r = 6) = 0.10420

 

So the total P is:

P (r = 0 to 6) = 0.01831 + 0.07326 + 0.14652 + 0.19537 + 0.19537 + 0.15630 + 0.10420

P (r = 0 to 6) = 0.88933

 

 

=> So the probability that 7 or more people will have the disease is:

P (r ≥ 7) = 1 - 0.88933

P (r ≥ 7) = 0.11067 = 11.067%

 

There is only 0.11067 or 11.067% probability that 7 or more will have the disorder.

Final answer:

To solve this problem, we can use the binomial probability formula. The probability of exactly x successes in n trials is given by the formula. In this case, the probability of success (p) is 0.00004, and the total number of trials (n) is 100,000. To find the probability that seven or more people will have the rare blood disorder, we need to calculate the sum of the probabilities for x = 7, 8, 9, ..., 100,000.

Explanation:

To solve this problem, we can use the binomial probability formula. The probability of exactly x successes in n trials is given by the formula:



P(x) = C(n, x) * p^x * (1 - p)^(n - x)



where:



P(x) is the probability of x successes

C(n, x) is the number of combinations of n trials and x successes

p is the probability of success in a single trial

n is the total number of trials



In this case, the probability of success (p) is 0.00004, and the total number of trials (n) is 100,000.

The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x. What is the constant of variation? What is the equation representing the direct variation?

Answers

Answer:

Part 1) The constant of variation is [tex]k=1/9[/tex]

part 2) The equation is [tex]y=\frac{1}{9}x[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

Let

x -----> the number of square feet

y ----->  the number of square yards

Three square yards are equivalent to 27 square feet

so

we have the point (27,3)

Part 1) What is the constant of variation?

The constant of variation or proportionality is equal to

[tex]k=y/x[/tex]

substitute the values

[tex]k=3/27[/tex]

Simplify

[tex]k=1/9[/tex]

Part 2) What is the equation representing the direct variation?

we know that

[tex]y=kx[/tex]

substitute the value of k

[tex]y=\frac{1}{9}x[/tex]

This equation shows that the number of square yards (y) is directly proportional to the number of square feet (x) with a constant of variation equal to 1/9.

In direct variation, the relationship between two variables can be represented by the formula:

y = kx

Where:

- y represents one variable (in this case, the number of square yards).

- x represents the other variable (in this case, the number of square feet).

- k is the constant of variation, which remains the same for all data points in the direct variation.

In this specific case, you've mentioned that 3 square yards are equivalent to 27 square feet. You can use this information to find the constant of variation (k). You can choose one of the data points to solve for k. Let's use the point (3, 27):

3 = k * 27

Now, solve for k:

k = 3 / 27

k = 1 / 9

So, the constant of variation (k) is 1/9. The equation representing the direct variation is:

y = (1/9)x

This equation shows that the number of square yards (y) is directly proportional to the number of square feet (x) with a constant of variation equal to 1/9.

Which layer of the osi model is most directly impacted when an internet services provider is found to be blocking udp traffic from a source host?

Answers

Answer:

UDP- User Datagram protocol (UDP), is a part of internet protocol suite. It is basically present on the Transport layer of the "Internet Network Model"

Step-by-step explanation:

As the Transport layer  of the model, the UDP, SCTP and TCP's are present. Now originally in the TCP/IP model there are four layers:

Host-to-network layer,Network layer,Transport layer,And the Application layer.Now, as the blockage occurred is from source to host then the data flow through the channel on specific internet protocols will halt, so the Host-to-Network layer is been affected by this blockage.

The correct layer of the OSI model that is most directly impacted when an internet service provider (ISP) is found to be blocking UDP traffic from a source host is the Transport Layer.

The OSI model consists of seven layers, with the Transport Layer being the fourth layer. This layer is responsible for providing communication services directly to the application processes running on different hosts. The Transport Layer is where protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) operate.

UDP (User Datagram Protocol) is a transport layer protocol that is used for sending messages (datagrams) in an internet protocol network. It is an alternative to the TCP protocol and is known for its simplicity and efficiency, particularly in cases where error checking and ordering are not necessary.

When an ISP blocks UDP traffic, it is directly interfering with the way the Transport Layer functions for applications that rely on UDP for data transmission. This action prevents UDP packets from being delivered to the intended destination, which can affect applications and services that use UDP for real-time data transmission, such as VoIP (Voice over Internet Protocol), online gaming, and streaming services.

The other layers of the OSI model are not directly impacted by the blocking of UDP traffic:

1. Physical Layer: Deals with the transmission and reception of the unstructured raw bit stream over a physical medium.

2. Data Link Layer: Responsible for node-to-node data transfer and error detection and handling.

3. Network Layer: Manages device addressing, tracks the location of devices on the network, and determines the best way to move data.

4. Transport Layer: Provides transparent transfer of data between end systems, or hosts, and is responsible for end-to-end error recovery and flow control.

5. Session Layer: Manages sessions between end-users, i.e., the opening, closing, and management of sessions between end-user applications.

6. Presentation Layer: Transforms data to provide a standard interface for the Application Layer. It is responsible for data encryption and decryption, as well as data compression.

7. Application Layer: Provides network services to the applications of the user, such as email, file transfer, and web browsing.

Since UDP operates at the Transport Layer, this is the layer most directly impacted by the ISP's decision to block UDP traffic.

Dario increased his savings from $350 to $413. While Monica increased her savings from $225 to $270. Who had a higher percent of increased in savings. The difference in the percents of increase is

Answers

The percentage in increase can be calculated as follows:
% of increase = (difference between new and old amounts / old value) *100

For Dario:
difference in values = 413 - 350 = 63
% of increase = (63/350)*100 = 18%

For Monica:
difference in values = 270 - 225 = 45
% of increase = 20%

Therefore,
Monica has higher percent of increase.
The difference in percents = 20% - 18% = 2%

clay is reading a map to decide his vacation route. The map has a scale of 1cm equals 18miles. If he estimates the length of his vacation route on a map is 14 centimeters what is the length in miles

Answers

The scale is 1 cm equals 18 miles.
If a distance on the map is 14 cm, it is 14 times larger than 1 cm.
That means the real distance is 14 times larger than 18 miles.
What is 14 * 18 miles?

Using the map scale of 1cm equals 18 miles, the actual length of Clay's vacation route is calculated as 252 miles by multiplying 14 centimeters (the length on the map) by 18 miles (the scale conversion factor).

Clay is using a map scale to plan his vacation route. The scale of the map is given as 1cm equals 18 miles. To calculate the actual length of Clay's vacation route in miles, we can set up a simple proportion. Since 1cm on the map represents 18 miles in reality, we multiply the length on the map, which is 14 centimeters, by 18 to find out how many miles this length represents:

Length in miles = 14 cm * 18 miles/cm

After performing the multiplication, we get:

Length in miles = 252 miles

Therefore, Clay’s vacation route is 252 miles long according to the map's scale.
