Step-by-step explanation:

If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The central angle is double the angle at the periphery that was subtended by the same chords.

Both the extreme points of the chords are connected to the circle. Then the two triangles are formed whose two sides are the radius of the circle that is congruent to each other. Then the triangle will be an isosceles triangle.

And the chord length is also congruent. Then the triangles are congruent to each other by SSS postulates.

If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

Step-by-step explanation:

To find the probability for a male patient to have B blood, find the number of male patients who do have B blood and divide it by the number of patients with type B.

The number of male and B blood is 99.

The number of patients with B blood is 183.

The probability is 99/183 = 0.54.

The percent is found by multiplying by 100.

0.54*100 = 54%

Answers:

=======================================================

Explanation:

Any exponential function is of the form y = a*b^x

Comparing that to y = 475*(0.5)^x, we see that a = 475 and b = 0.5

Set b equal to 1+r and solve for r

1+r = 0.5

r = 0.5-1

r = -0.5

The negative r value tells us that the growth rate is -50%, in other words, we have a 50% decay rate. The amount drops by 50% each time x goes up by 1. This is the same as saying the amount cuts in half each time x goes up by 1.

-----------------------

Lastly, plug in x = 3 to find f(3)

f(x) = 475(0.5)^x

f(3) = 475(0.5)^3

f(3) = 59.375

f(3) = 59.4

Consider the given function,

Note that there is a rational part of the function.

And for any rational expression, the denominator can never be zero. So we have to exclude the values for which the denominator becomes zero,

So the domain of the function will be the set of real numbers excluding the number -7 .

Since 'x' can never reach infinity, it follows that,

So the range of the function will be the set of all real numbers excluding -5.

For a standard normal distribution, given p(z < c) = 0.624, we need to the balance  value of c.

This means that we need to find the z-value that has an area of 0.624 to the left of it in a standard normal distribution.To find this value, we can use a standard normal table or a calculator with a standard normal distribution function.Using a standard normal table:We look up the area of 0.624 in the body of the table and find the z-value in the margins. The closest area we can find is 0.6239, which corresponds to a z-value of 0.31.

Therefore, c = 0.31.Using a calculator:We can use the inverse normal function of the calculator to find the z-value that corresponds to an area of 0.624 to the left of it. The function is denoted as invNorm(area to the left, mean, standard deviation). For a standard normal distribution, the mean is 0 and the standard deviation is 1. Therefore, we have:invNorm(0.624, 0, 1) = 0.31Therefore, c = 0.31.

Simple Random sampling

Meaning:

Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected.

For example, if you randomly select 1000 people from a town with a population of 100,000 residents, each person has a 1000/100000 = 0.01 probability. That's a simple calculation requiring no additional knowledge about the population's composition. Hence, simple random sampling.

Advantage:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling.

22 per minute

?   Per 3 minutes

22 x 3 = 66

Answer: The position of the whale relative to the surface of the water can be determined by multiplying the rate at which it descends (22 feet per minute) by the amount of time it has been descending (3 minutes).

Position = Rate x Time

Position = 22 feet/minute x 3 minutes = 66 feet

So, after diving for 3 minutes, the position of the whale relative to the surface of the water is 66 feet.

It means the whale descended for 66 feet from the surface level of the water.

Please keep in mind that this information is assuming a linear motion, without taking into account any other factors that could affect the whale's descent such as currents or obstacles in the water.

Step-by-step explanation:

The function h(t) represents the value of Mark's account after t years, considering both a constant function f(t) and an exponential function g(t).

Therefore, the correct option is:

$3694

The constant function f(t) is given as f(t) = 2500, which means Mark's account will have $2500 regardless of the number of years.

The exponential function g(t) is given as g(t) = 1.05^t. This function represents the growth of Mark's account with an interest rate of 5% (1.05 is the factor representing a 5% increase).

To determine the value of the account after 8 years, we need to calculate h(8) by combining the two functions:

h(t) = f(t) * g(t)

h(8) = f(8) * g(8)

h(8) = 2500 * (1.05^8)

Let's calculate the value:

h(8) ≈ 2500 * 1.46933

h(8) ≈ 3673.325

Rounding to the nearest dollar, the value of the account after 8 years is approximately $3,673.

To find the width of the border surrounding a photo printed on an 11 by 13 piece of paper, we can calculate the area of the paper and subtract the area of the photo to obtain the area of the border.

The area of the paper is given by the dimensions of the paper, which is 11 by 13, resulting in an area of 11 * 13 = 143 square units.

Given that the photo takes up 80 square units, we can calculate the area of the border by subtracting the area of the photo from the area of the paper: 143 - 80 = 63 square units.

Dividing the area of the border (63) by the length of one side of the paper (11 or 13) will give us the width of the border. The result will vary depending on which side we choose.

For example, if we divide 63 by 11, we get a width of approximately 5.727 units.

Therefore, the width of the border is approximately 5.727 units, assuming we divide the area of the border by the length of one side of the paper (11 or 13).

For the two given parabolas we will see:

1) A is increasing.

2) both functions are negative is (-7, -2)

3) B has the largest value when x = -3.

First, we know that both functions are parabolas.

By looking at the table that defines function B, we can see that the interval in which this function decreases is from x = -1 onwards. So the interval is:

[-1, ∞)

Now, if you look at the graph for parabola A, you can see that it is increasing on that interval.

Parabola B is almost always negative, except for x = -1.

Parabola A is negative in the interval (-7, -2)

Then we conclude that the interval in where both functions are negative is (-7, -2)

For function A:

A(-3) = -5

For function B:

B(-3) = -3

So function B has the greatest value when x = -3.

Caliban's diminished threat and importance by the end of the play serves a specific purpose in Shakespeare's "The Tempest." It highlights the theme of colonization and power dynamics, as well as challenges stereotypes and prejudices associated with "the other."

Caliban, initially depicted as a savage and dangerous creature, gradually loses his menacing presence as the play unfolds. This transformation is intentional, aiming to convey a deeper message about the dehumanizing effects of colonization. By the end, Caliban's character becomes a symbol of the oppressed and marginalized, reflecting the consequences of exploitation and subjugation. Through this portrayal, Shakespeare prompts the audience to question their preconceived notions and biases, challenging the notion that power and civility are inherently linked to physical appearance or societal status. Additionally, Caliban's character serves as a contrast to the other characters in the play. While Prospero represents civilization and control, Caliban embodies the natural and untamed. This stark dichotomy underscores the broader theme of the clash between the civilized and the wild. Ultimately, Caliban's transformation serves to provoke introspection and stimulate conversations about the treatment of those deemed different or inferior in society.
