in a large population, 64% of the people have been vaccinated. if 3 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated can be calculated using the binomial probability formula.
The binomial probability formula is used to calculate the probability of a given number of successes from a given number of trials when the probability of success is constant. In this case, the number of trials is 3 (i.e. the three randomly selected people) and the probability of success is 64% (i.e. the probability that each of the randomly selected people has been vaccinated).
To calculate the probability that at least one of the three randomly selected people has been vaccinated, we first calculate the probability of none of them having been vaccinated:
P(none) = (1 - 0.64)^3 = 0.216
Then, the probability of at least one of them having been vaccinated is 1 - P(none) = 1 - 0.216 = 0.784.
In conclusion, the probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

What is Pythagοrean theοrem?The Pythagοrean theοrem is a fundamental result in Euclidean geοmetry that describes the relatiοnship between the three sides οf a right-angled triangle.
In equatiοn fοrm, this can be written as:
c² = a² + b²
where c is the length οf the hypοtenuse, and a and b are the lengths οf the οther twο sides (alsο knοwn as the legs) οf the right-angled triangle.
In this case, the tοwer, the grοund, and the guy wire fοrm a right triangle. We knοw the height οf the tοwer is 45 ft, and the hοrizοntal distance frοm the base οf the tοwer tο where the guy wire is secured tο the grοund is 28 ft. Let's call the length οf the guy wire c. Then, we have:
a = 28 ft (hοrizοntal distance frοm the base οf the tοwer tο where the guy wire is secured)
b = 45 ft (height οf the tοwer)
c = length οf the guy wire (hypοtenuse)
Using the Pythagοrean theοrem, we can sοlve fοr c:
[tex]a^2 + b^2 = c^2[/tex]
[tex]28^2 + 45^2 = c^2[/tex]
[tex]784 + 2025 = c^2[/tex]

The temperature in a town is 36.6°F during the day and -18.6°F at night. Find the difference in the temperatures.
Answer:
Step-by-step explanation:
To find the difference between the temperatures, we need to subtract the night temperature from the day temperature.
Difference = Day temperature - Night temperature
Difference = 36.6°F - (-18.6°F) (Note: Subtracting a negative number is the same as adding the positive number)
Difference = 36.6°F + 18.6°F
Difference = 55.2°F
Therefore, the difference in temperature between day and night in the town is 55.2°F.
a librarian has 10 nonfiction and eight fiction books from which to choose the next three book club selections.what is the approximate probability that she chooses a fiction book, then a nonfiction book, then a fiction book?
The probability that a librarian chooses a fiction book, then a nonfiction book, then a fiction book is approximately 0.305.
The solution to this problem is a probability calculation.
To calculate the probability of selecting a fiction book, then a nonfiction book, then a fiction book from a selection of 10 nonfiction books and eight fiction books, we need to use the multiplication rule of probability.
The multiplication rule states that the probability of two or more independent events happening together is equal to the product of their individual probabilities.
To apply this rule, we'll break down the question into three events:
Probability of choosing a fiction book = 8/18 = 4/9
Probability of choosing a nonfiction book (after selecting a fiction book) = 10/17
Probability of choosing a fiction book (after selecting a nonfiction book) = 8/16 = 1/2
Now we can use the multiplication rule:4/9 * 10/17 * 1/2 = 0.305 (rounded to three decimal places)
Therefore, the approximate probability that the librarian will choose a fiction book, then a nonfiction book, then a fiction book is 0.305.

There are 35 counters in a bag the ratio of red to blue counters is 2:5 there are 9 more blue counters the rest are green how many green counters are there?
there are 6 red counters, 24 blue counters, and 5 green counters in the bag, based on the given information. The given information provides us with the ratio of red to blue counters in a bag, which is 2:5. This means that for every 2 red counters in the bag, there are 5 blue counters.
Let the number of red counters in the bag be 2x, where x is a constant. Then, the number of blue counters in the bag is 5x. We are also given that there are 9 more blue counters than before, so the new number of blue counters is 5x + 9.
We know that there are 35 counters in total, so we can write an equation based on this information:
2x + 5x + 5x + 9 = 35
Simplifying this equation, we get:
12x + 9 = 35
Subtracting 9 from both sides, we get:
12x = 26
Dividing both sides by 12, we get:
x = 2.1667
Since we cannot have a fraction of a counter, we can round x up to 3.
Therefore, the number of red counters in the bag is 2x = 2(3) = 6, and the number of blue counters in the bag is 5x + 9 = 5(3) + 9 = 24.
Finally, we can find the number of green counters in the bag by subtracting the number of red and blue counters from the total number of counters:
35 - 6 - 24 = 5
So there are 5 green counters in the bag.
In summary, there are 6 red counters, 24 blue counters, and 5 green counters in the bag, based on the given information.

Hence, the answer is (4, 3, 1).In conclusion The answer provided above is concise and ng factually correct, and it addresses the question directly.
In order to determine the number of total electron groups, bondiroups, and lone pairs for geometry (a), we need to use the VSEPR theory. According to this theory, the electron groups around a central atom in a molecule will arrange themselves in a way that minimizes their repulsion. The total number of electron groups includes both the bonding and lone pairs of electrons.To determine the number of electron groups for geometry (a), we first need to determine the molecular geometry of the molecule.
From the given name, we can assume that geometry (a) is tetrahedral. In a tetrahedral molecule, there are four electron groups: three bonding groups and one lone pair. Therefore, the number of total electron groups for geometry (a) is four, the number of bonding groups is three, and the number of lone pairs is one.

a lottery offers one $1000 prize, one $500 prize, and five $100 prizes. one thousand tickets are sold at $3 each. find the expectation if a person buys one ticket.
the expectation of buying one ticket is $2
Expectation if a person buys one ticket A person is interested in buying a ticket for a lottery that offers one $1000 prize, one $500 prize, and five $100 prizes. One thousand tickets are sold at $3 each. The expected return is calculated using the following formula:
Expectation = (Probability of winning Prize 1 × Value of Prize 1) + (Probability of winning Prize 2 × Value of Prize 2) + (Probability of winning Prize 3 × Value of Prize 3)To determine the expectation, we must first determine the probability of winning each of the three prizes.
Since one thousand tickets are sold and only one person can win the first prize, the probability of winning the $1000 prize is 1/1000 or 0.001. Similarly, the probability of winning the $500 prize is 1/1000 or 0.001. Since five $100 prizes are available and only one person can win each prize, the probability of winning any one of the five $100 prizes is 5/1000 or 0.005.
Therefore, the expectation is calculated as follows: Expectation = (0.001 × $1000) + (0.001 × $500) + (0.005 × $100)Expectation = $1 + $0.50 + $0.50Expectation = $2Thus, the expectation of buying one ticket is $2. This means that the average value of a ticket is $2, and a person can expect to win $2 on average by purchasing a ticket. Since the cost of a ticket is $3, the expected return is less than the cost of the ticket, and therefore, it is not a good investment from a financial standpoint.

Write the linear equation in standard form y=19/14x+13
The linear equation in standard form is 19x - 14y = -182.
What is Linear equation?
A linear equation is a mathematical equation that describes a straight line on a graph. In other words, it is an equation that relates a variable or variables to a constant through a linear function, where the highest power of the variable is one. A general form of a linear equation is:
y = mx + b
To write the linear equation in standard form Ax + By = C, where A, B, and C are integers and A is positive, we need to get rid of the fraction in the equation.
To do this, we can multiply both sides of the equation by the denominator of the fraction, which is 14. This gives:
14y = 19x + 182
Next, we can rearrange this equation by subtracting 19x from both sides:
-19x + 14y = 182
Finally, we can multiply both sides of the equation by -1 to make the coefficient of x positive:
19x - 14y = -182
So, the linear equation in standard form is 19x - 14y = -182.

Frank is building a playhouse for his daughter.
The playhouse is a composite figure with a floor and no windows.
The playhouse is a rectangular prism and a triangular prism.
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh,
where l is the length,
w is the width,
and h is the height.
Therefore, the surface area of the rectangular prism portion of the playhouse can be calculated by substituting the given values into the formula.
Surface area of the rectangular prism = 2lw + 2lh + 2wh
For the rectangular prism, l = 10 feet, w = 8 feet, and h = 6 feet.
Substituting the values in the formula.
Surface area of the rectangular prism
= 2lw + 2lh + 2wh
= 2 (10 feet × 8 feet) + 2 (10 feet × 6 feet) + 2 (8 feet × 6 feet)
= 160 feet2 + 120 feet2 + 96 feet2= 376 feet2
The surface area of the rectangular prism of the playhouse is 376 square feet.
The formula for the surface area of a triangular prism is 2lw + lh + ph,
where l is the length, w is the width, h is the height, and p is the slant height.
Therefore, the surface area of the triangular prism portion of the playhouse can be calculated by substituting the given values into the formula.
Surface area of the triangular prism = 2lw + lh + ph
For the triangular prism, l = 8 feet, w = 5 feet, h = 6 feet, and p = 10 feet.
Substituting the values in the formula.
Surface area of the triangular prism = 2lw + lh + ph= 2 (8 feet × 5 feet) + (8 feet × 6 feet) + (10 feet × 6 feet)= 80 feet2 + 48 feet2 + 60 feet2= 188 feet2
The surface area of the triangular prism of the playhouse is 188 square feet.
The total surface area of the playhouse can be found by adding the surface area of the rectangular prism and the surface area of the triangular prism.
Surface area of the playhouse = surface area of rectangular prism + surface area of triangular prism.

. cards are dealt from a standard shuffled deck of cards until the first ace is drawn. what is the chance that the next card is a king?
Cards are dealt from a standard shuffled deck of cards until the first ace is drawn. So the chance that the next card is a king is 0.05 percent.
When drawing a card from a standard deck of 52 cards, the chance of drawing an ace is 4/52 or 1/13. After an ace has been drawn, there are 51 cards left in the deck, and 4 of them are kings.
So, the probability of drawing an ace and then a king is
(1/13) × (4/51) = 4/663.
There are 4 different aces that could be drawn, each with the same probability of
(1/13) × (4/51) = 4/663,
So we multiply by 4 to account for all the possible aces that could be drawn.
Therefore, the total probability of drawing an ace and then a king is
(4/663) × 4 = 16/663.
Once an ace has been drawn, there are 51 cards remaining in the deck, and only one of them is a king. Therefore, the probability of drawing a king after an ace has been drawn is 1/51.
The probability that the next card is a king after the first ace is drawn is thus:
(16/663) × (1/51) = 16/33663

A human organism developing in the uterus from the ninth week until birth is called a (n) ____________.`
A human organism developing in the uterus from the ninth week until birth is called a(n) fetus.
A fetus is the term used to describe a human organism that is developing in the uterus from the ninth week of gestation until birth. During this time, the fetus undergoes significant growth and development, as all of the major organs and body systems are formed and begin to function.
The ninth week of gestation is considered a significant milestone in fetal development, as most of the critical stages of organogenesis have been completed by this time. From this point onward, the fetus primarily grows and matures in preparation for life outside of the womb.
