The rule that describes the transformation is (x, y) → (y, -x)

We are given that;

The points (-2,5),(2,5),(2,1).

Now,

To rotate a point 90° clockwise with the origin as the center of rotation, we can use the following rule:

(x, y) → (y, -x)

This means that the x-coordinate of the original point becomes the y-coordinate of the new point, and the y-coordinate of the original point becomes the opposite of the x-coordinate of the new point.

For example, applying this rule to the point (-2, 5), we get:

(-2, 5) → (5, 2)

Therefore, by the transformation the answer will be(x, y) → (y, -x)

The similarity ratio between the two octagons is 1:2 (Option b).

To begin, we need to know that similar figures have the same shape, but they may differ in size. For instance, we can have two octagons with different areas but the same shape. In this case, we are given that the two octagons are similar, and we are given the areas of the two octagons.

Let the similarity ratio between the two octagons be "x". For areas, we know that the ratio of the areas of two similar figures is the square of their similarity ratio. Therefore, we can set up the following equation:

x² = (Area of smaller octagon) / (Area of larger octagon)

Substituting the given areas, we get:

x² = 4 / 16    

x² = 0.25

Taking the square root of both sides, we get:

x = √0.25

x = 0.5

Therefore, the similarity ratio between the two octagons is 1:2 (Option b).

The coordinates of the vertices for the image triangle after a translation 3 units up are A'(-3, 6), B'(0, 10), and C'(-3, 3). (option b)

Let's first visualize the given triangle ABC with vertices at A(-3, 3), B(0, 7), and C(-3, 0). We can plot these points on a coordinate plane and connect them to form the triangle. Now, let's consider the translation that moves the triangle 3 units up. This means that we need to add 3 to the y-coordinate of each vertex to get the coordinates of the image.

So, the coordinates of the vertices of the image triangle, let's call it A'B'C', will be:

A' = (-3, 3+3) = (-3, 6)

B' = (0, 7+3) = (0, 10)

C' = (-3, 0+3) = (-3, 3)

Now, we can plot these points and connect them to form the image triangle A'B'C'. We can see that the image triangle is simply the original triangle translated 3 units up.

Hence the correct option is (b).

Hypertension is known as the silent killer because often, early hypertension is asymptomatic. a systolic blood pressure of  140 mm Hg would make us concerned the patient was hypertensive.

Here, we know that Asymptomatic:

Any condition that a patient tests positive for but does not manifest any symptoms of is referred to in medicine as being asymptomatic. After a diagnosis, a medical illness may be deemed asymptomatic if no obvious symptoms emerge.

Absence of symptoms is referred to be asymptomatic. If your doctor says you are asymptomatic, this indicates you have a disease or condition but don't show any symptoms or outward indicators of being ill.

Instances of sickness that are symptom-free for all or part of the time are frequently referred to be asymptomatic. Pre-symptomatic, however, is a word sometimes used to describe patients that initially have no symptoms but later develop them.

The table shows that the highest level of education achieved among the 450 adults surveyed by the National Society of Acupuncturists was a bachelor's degree or higher, with 240 respondents having achieved this level of education. The next highest level of education was a high school diploma or equivalent, with 120 respondents having achieved this level. There were also 60 respondents with some college education but no degree, and 10 respondents with a graduate degree.

Based on this information, it appears that there is a positive correlation between education level and the belief that acupuncture is a reasonable form of medicine. This could be due to a variety of factors, such as increased exposure to scientific and medical knowledge through education, a more open-minded and skeptical approach to healthcare, or a greater willingness to try alternative therapies. It is important to note, however, that correlation does not necessarily imply causation, and there may be other factors at play that are not captured by this data.

The probability that the customer is served by Charter with market share of 30% is equal to 34.9%.

Let A be the event that the customer is served by Charter,

and B be the event that the customer is experiencing an internet speed of 12Mbps.

Probability of A given B, which can be written as P(A|B).

Use Bayes' theorem to find P(A|B),

P(A|B) = P(B|A) × P(A) / P(B)

P(A) = 0.3 (the market share of Charter)

and P(B) = P(B/A) × P(A) + P(B / A') × P(A'),

where P(A') = 1 - P(A) = 0.7 (the market share of Xfinity).

P(B|A), the probability of experiencing an internet speed of 12Mbps given that the customer is served by Charter,

All speeds between 7Mbps and 15Mbps are equally likely.

This implies, the probability of experiencing a speed of 12Mbps given Charter is,

P(12Mbps/A) = 1 / (15Mbps - 7Mbps)

                     = 1 / 8

P(B|A'), the probability of experiencing an internet speed of 12Mbps given that the customer is served by Xfinity,

All speeds between 10Mbps and 20Mbps are equally likely.

This implies, the probability of experiencing a speed of 12Mbps given Xfinity is,

P(12Mbps|A') = 1 / (20Mbps - 10Mbps)

                     = 1 / 10

Now substitute all the values into Bayes' theorem,

P(A|B) = P(B|A) × P(A) / [P(B|A) × P(A) + P(B |A') × P(A')]

= (1/8) × 0.3 / [(1/8) × 0.3 + (1/10) × 0.7]

= 0.349

Therefore, the probability that the customer is served by Charter given that they are experiencing an internet speed of 12Mbps is 0.255, or about 34.9%.

Using the system of equations, the number of adults and the number of children who were committed are 140 and 104 respectively.

Given that,

The admission fee at an amusement park is $1.50 for children and $4 for adults.

Let x be the number of adults and y be the number of children who were admitted.

On a certain day, 244 people entered the park, and the admission fees collected totaled 716.00 dollars.

We get a system of equations,

x + y = 244

4x + 1.5y = 716

From the first equation,

y = 244 - x

Substituting this to second equation,

4x + 1.5(244 - x) = 716

4x + 366 - 1.5x = 716

2.5x = 350

x = 140

y = 244 - x = 104

The percentage of saline solution in brand B is 3%. Then the correct option is B.

Let x be the percent of saline solution in brand B.

Since Danielle combined brands A and B to create a total of 18 gallons of 8% saline solution, we know that the total volume of saline solution in the combination is 18% of 6 gallons + x% of (18 - 6) gallons.

Thus, we can set up the equation:

0.18(6) + 0.01x(18 - 6) = 0.08(18)

Simplifying and solving for x, we get:

1.08 + 0.12x = 1.44
