Answer:

\(\angle\,A=72^o\\\angle\,B=108^o\)

Step-by-step explanation:

Notice that buy construction of a parallelogram,the angles \(\angle \,A\) and \(\angle \,C\) must equal each other. Then, based on the info given,  we can write the following equation:

\(3\,y+27^o=5\,y-3^o\\27^o+3^o=5\,y-3\,y\\30^o=2\,y\\y=15^o\)

Then, angle \(\angle \,A\) =\(5\,(15^o)-3^o=72^o\)  which is also equal to angle B

and since the addition of all internal angles of the parallelogram must equal \(360^o\) , then:

\(B+D=360^o-72^o-72^o=216^o\)

and therefore, since \(\angle \,B\) and \(\angle \,D\)  must be equal, then:

\(\angle\,B=\frac{216^o}{2} =108^o\)

The two statements that also describe features of a binomial experiment are: "The random variable counts the number of successes in a fixed number of trials" and "The probability of success stays the same for each trial."

Binomial experiments also have independent trials, which means that the outcome of one trial does not affect the outcome of another trial. Additionally, binomial experiments can only have two possible outcomes - success or failure - for each trial. The distribution of a binomial experiment is not always asymmetric in shape, as it can be symmetrical or skewed depending on the parameters of the experiment.

Finally, subsequent trials in a binomial experiment are not conditional probabilities, as each trial is independent and the probability of success remains constant.
Based on your question and the terms provided, the two statements that describe features of a binomial experiment are:

1. The random variable counts the number of successes in a fixed number of trials.
2. The probability of success stays the same for each trial.

A binomial experiment has independent trials with a constant probability of success, and it focuses on counting the number of successes within a specific number of trials.

Hence, minimum monthly payment to be made to pay off the whole debt in 14 months = $244.15

28 and 45 centimeters, because they are the two shortest sides.

Option D is the correct answer.

We have,

In a right triangle, the side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

In this case,

The side lengths given are 28 centimeters, 45 centimeters, and 53 centimeters.

To determine the lengths of the legs, we need to identify the two shorter sides.

In this triangle,

28 centimeters and 45 centimeters are the two shorter sides, and 53 centimeters are the hypotenuse.

We can verify that 28 and 45 centimeters are the lengths of the legs by using the Pythagorean theorem:

28² + 45² = 784 + 2025 = 2809

53² = 2809

The equation is satisfied, indicating that 28 and 45 centimeters are indeed the lengths of the legs in this right triangle.

Thus,

28 and 45 centimeters, because they are the two shortest sides.

Answer:

-23\(x^{8}\)-2v

Step-by-step explanation:

The perimeter of the right triangle based on given points will be equal to 24 units. Hence, option B is correct.

A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any geometric two-dimensional shape. The circumference of several figures could be compared based on the measurements.

As per the data available in the question,

The right triangle displayed contains three vertex locations: (-4, 4), (4, 4), and (-4, 4). (4, -2). The distance formula can be used to determine the length of a side between the initial two vertices:

distance = \(\sqrt{ ((x_2 - x_1)^2 + (y_2 - y_1)^2)}\)

= √((4 - (-4))² + (4 - 4)²)

=√(8² + 0)

= √(64)

= 8

Using the distance formula, one can figure out how long the side is between the first and second vertices:

distance =\(\sqrt{ ((x_2 - x_1)^2 + (y_2 - y_1)^2)}\)

= √((4 - 4)² + (-2 - 4)²)

= √(0 + (-6)²)

= √(36)

= 6

The Pythagorean theorem can be used to determine the right triangle's hypotenuse's length:

c² = a² + b²

c = √(a + b²)

= √(8² + 6²)

= √(64 + 36)

= √(100)

c = 10

To find the perimeter (P) add all the sides,

P = 8 + 6 + 10 = 24 units.

A 17-adult sample with a mean score of 77 on a standardized personality test has a 90% confidence interval of (74.7, 79.3). The sample size is 17, and the population standard deviation is 4. The formula calculates the value of\(z_{(1-\frac{\alpha}{2})}\) at 90% confidence interval, which is 1.645. The lower limit is 74.7, and the upper limit is 79.3.

Given data: A random sample of 17 adults has a mean score of 77 on a standardized personality test, with a standard deviation of 4. (A higher score indicates a more personable participant.)We can calculate the 90% confidence interval for the mean score of all takers of this test by using the formula;

\($$\overline{x}-z_{(1-\frac{\alpha}{2})}\frac{\sigma}{\sqrt{n}}<\mu<\overline{x}+z_{(1-\frac{\alpha}{2})}\frac{\sigma}{\sqrt{n}}$$\)

Where \($\overline{x}$\) is the sample mean,

σ is the population standard deviation,

n is the sample size, α is the significance level, and

z is the z-value that corresponds to the level of significance.

To find the values of\($z_{(1-\frac{\alpha}{2})}$\), we can use a standard normal distribution table or use the calculator.

The value of \($z_{(1-\frac{\alpha}{2})}$\) at 90% confidence interval is 1.645. The sample size is 17. The population standard deviation is 4. The sample mean is 77.

Now, putting all the given values in the formula,

\($$\begin{aligned}\overline{x}-z_{(1-\frac{\alpha}{2})}\frac{\sigma}{\sqrt{n}}&<\mu<\overline{x}+z_{(1-\frac{\alpha}{2})}\frac{\sigma}{\sqrt{n}}\\77-1.645\frac{4}{\sqrt{17}}&<\mu<77+1.645\frac{4}{\sqrt{17}}\\74.7&<\mu<79.3\end{aligned}$$\)

Therefore, the 90% confidence interval for the mean score of all takers of this test is (74.7, 79.3). So, the lower limit of the 90% confidence interval is 74.7, and the upper limit of the 90% confidence interval is 79.3.

The number of functions from a set X with m elements to a set Y with n elements is given by  \(n^{m}\)

This is because for each element in X, there are n possible elements in Y to which it can be mapped. So, for each of the m elements in X, there are n choices, giving a total of n * n * ... * n (m times) possible functions.

The number of injections (or one-to-one functions) from a set X with m elements to a set Y with n elements is given by the number of ways to choose m elements from a set of n elements, which is given by the binomial coefficient C(n, m).

This is because an injection must map each element in X to a distinct element in Y, so the number of injections is equal to the number of ways to choose m elements from n elements without repetition.

Angle-Side-Angle (ASA) theorem states that if two triangles are considered congruent, then the two corresponding angles equal to each other will include a corresponding side that is equal to each other.

By applying the Side Angle Side Postulate (SAS), you can also be sure your two triangles are congruent. Here, instead of picking two angles, we pick a side and its corresponding side on two triangles.

The SAS Postulate says that triangles are congruent if any pair of corresponding sides and their included angle are congruent.

For a table of values to be a linear form, the difference between the x and y values must be equal and must be able to be written in the form Ax + By = C

According to table B, we can use the following coordinate points from the table:

(-1, 4) and (2, 1)

Get the slope:

Slope m = (1-4)/2-(-2)

Slope m = -3/4

Get the y-intercept

Recall that y = mx + b

Using the coordinate (2, 1) and the slope m = -3/4

1 = -3/4(2) + b

1 = -3/2 + b

b = 1 + 3/2

b = 5/2

Get the required equation in the form y = mx + b

The slope of both lines are negative reciprocals, therefore, 6x + 10y = 20 and 5x - 3y = 21 are perpendicular lines.

If the equations of each given line is rewritten or expressed in the slope-intercept form as y = mx + b, the value of the slopes, m, of lines that are parallel would be the same.

On the other hand, if the values of the slope (m), of both lines are negative reciprocal, then the lines are perpendicular.

Given the two equations of a line, 6x + 10y = 20 and 5x - 3y = 21, rewrite in slope-intercept form to determine their slope values.

6x + 10y = 20 is rewritten as y = -3/5x + 2. The slope (m) = -3/5.

5x - 3y = 21 is rewritten as y = 5/3x - 7. the slope (m) = 5/3.

What is the cylindrical shell?

A region enclosed by two identically sized cylinders with the same central axis is known as a cylindrical shell. We often denote the height of the cylinders by H, the inner cylinder's radius by r, and the thickness of the shell by t, resulting in a larger cylinder's radius equal to r + t.

Here,

We consider a strip of height y = f(x), and width dx; it is x units away from the axis of rotation.

Now, we rotate this strip about the y-axis; we obtain a cylindrical shell with  

radius = x

height = f(x)

thickness = dx

The volume of cylindrical shell = (circumference)×(height)×thickness

= (2πx)×(f(x))×dx

The volume of revolution = 2π \(\int\limits^a_b {xf(x)} \, dx\)
