A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9. Each character in the password cannot be used more than once.

What is the approximate probability that exactly one of the four characters will be a number?

1%
11%
28%
44%

Answers

Answer 1
28 is the right answer sorry if I’m wrong
Answer 2

The approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9.

Total letters = 26

Total numbers = 10

Total = 10 + 26 = 36

Total possibilities = 36×35×34×33 = 1413720

Password with one number = C(10, 1) = 10

With three letters = C(26, 3) = = 2600

Outcomes = 2600×10 = 26000

Favorable outcomes = 26000×4! = 624000

Probability = 624000/1413720 = 0.44 = 44%

Thus, the approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

TEMPERATURE FOR THE WEEK? SHOW YOUR WORK

Answers

Answer:

-16°C

Step-by-step explanation:

The lov temperatures for a week are :

-15°C, -12 , -10°C, -12°C, -18°C, -20°C, and -25°C.

We need to find the mean love temperature for the week.

Total no. of observations = 7

Mean = sum of observations/total no of observations

[tex]M=-\dfrac{15+12+10+12+18+20+25}{7}\\\\M=-16^{\circ} C[/tex]

So, the mean temperature is -16°C.

Jayce bought 5 bath towels and returned 2 hand towels. His sister Jayna bought 3 bath

towels and returned 4 hand towels. Jayce paid a total of $124 and Jayna paid a total of

5b - 2h = 124

$24. The system of equations

models this situation, where b is the

3b - 4h = 24

price of a bath towel and h is the price of a hand towel. How much does each kind of

towel cost?

Answers

Answer:

Bath towels = $32

Hand towels = $18

Step-by-step explanation:

Given:

5b - 2h = 124 (1)

3b - 4h = 24 (2)

Multiply (1) by 2 to eliminate h

10b - 4h = 228 (3)

3b - 4h = 24 (2)

Subtract (2) from (3)

10b - 3b = 248 - 24

7b = 224

b = 224 / 7

b = 32

Substitute b = 32 into (2)

3b - 4h = 24

3(32) - 4h = 24

96 - 4h = 24

-4h = 24 - 96

-4h = -72

h = -72 / -4

= 18

h = 18

Bath towels = $32

Hand towels = $18

The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?

Answers

Answer:

Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?

Answers

Answer:

The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.

Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.

Step-by-step explanation:

First let's find the area:

5x² × 12x

= 60x³

Now the perimeter:

2(5x² + 12x)

= 10x² + 24x

There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.How does the speaker's metaphor of the mirage in paragraph 4 support the purpose of the speech? It develops the idea that voluntour opportunities are not what they appear to be. It emphasizes the idea that voluntour work is difficult and draining but worth the effort. It reveals the significant contribution that voluntours make to the areas they visit. It shows that voluntourism experiences can even take place anywhere-even in the desert.
