Step-by-step explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

P = (-5, 2)   Q = (-3, 6)

We see the y increase by 4 and x increase by 2, so the slope is

m = 4/2 = 2

The number of ways can arrange the songs on the CD will be 3,628,800.

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

Suppose Allen is going to burn a compact disk (CD) that will contain 10 songs.

Then the number of ways can arrange the songs on the CD will be given by 10 factorial.

⇒ 10!

⇒ 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

⇒ 3,628,800

Thus, the number of ways can arrange the songs on the CD will be 3,628,800.

The statement is true. The DecimalFormat class is part of the Java API, specifically within java.text package, so it is automatically available to your programs. You can use it to format numbers in various ways, such as for displaying currency or percentages.

DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.

To obtain a NumberFormat for a specific locale, including the default locale, call one of NumberFormat's factory methods, such as getInstance(). In general, do not call the DecimalFormat constructors directly, since the NumberFormat factory methods may return subclasses other than DecimalFormat. If you need to customize the format object, do something like this:

NumberFormat f = NumberFormat.getInstance(loc);

if (f instanceof DecimalFormat) {

    ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true);

}

A DecimalFormat comprises a pattern and a set of symbols. The pattern may be set directly using applyPattern(), or indirectly using the API methods. The symbols are stored in a DecimalFormatSymbols object. When using the NumberFormat factory methods, the pattern and symbols are read from localized ResourceBundles

The height of the triangular pyramid, given that the volume is 318 square centimeters 7.31 cm (option B)

First, we shall obtain the base area of the triangular pyramid. Details below:

A = ½bh

A = ½ × 29 × 9

A = 130.5 cm²

Finally, we shall determine the height of the triangular pyramid. Details below:

V = ⅓Ah

318 = ⅓ × 130.5 × h

318 = 43.5 × h

We need to know if the point C=(5,3) is on the line.

If so then we should have a valid equation when we

substitute in x = 5 and y = 3 into the equation.

3 = (3/5)(5)-1/5

3 = 3-1/5

3 = 2 4/5

Answer:

The basic formula to calculate each interior angle is [(n – 2) × 180°]/n; here, ‘n’ is the number of sides, which is ‘n’ = 5. Putting the formula’s ‘n’ value, we get [(5 – 2) × 180°]/5 = 108°. This means, for a regular pentagon, the value of each interior angle equates to 108°.

Step-by-step explanation:

The required general solution of the differential equation in implicit form y = \([(3/2) * (15x + C) * x^{-3}]^{-3/2}\).

The differential equation is a nonlinear equation and cannot be solved exactly by standard methods. One way to approach a solution is to try to find a substitution that transforms the equation into a separable form, where the variables can be separated and integrated separately. A common approach is to make the substitution y = v^(-2/3), which transforms the equation into:

3x^2 * (2/3) * v^(-5/3) * v' + 6x * v^(-2/3) = 15 * v^(-5/3)

Dividing both sides by v^(-5/3), we get:

3x^2 * (2/3) * v' + 6x * 3 * (2/3) * v^(1/3) = 15

This is now a separable differential equation, and we can integrate both sides to find the general solution:

∫(3x^2 * (2/3) * v' dx) = ∫(15 dx) + C

(2/3) * x^3 * v = 15x + C

v = (3/2) * (15x + C) * x^(-3)

Finally, substituting back for y = v^(-2/3), we get the general solution:

y = \([(3/2) * (15x + C) * x^{-3}]^{-3/2}\)

This is the general solution of the differential equation in implicit form. To find an explicit form, one could solve for C using initial or boundary conditions.

The complement of set Q {-4, -3, -2} if the universal set is P {-5, -4, -3, -2, -1} is defined by:

¬Q = {-5, -1}

If we have a set A defined in an universal set U, we define the complement of A as all the elements of U that are not elements of A.

In this case we have the sets:

P = {-5, -4, -3, -2, -1}

Q = {-4, -3, -2}

Here we want to find the complement of Q in P, so P is the universal set for this problem.

The elements of P that are not elements of Q are:

{-5, -1}

Answer:

x = 10

Step-by-Step Explanation:

Since this triangle is an isosceles, that means two sides are the same and so being that two sides are the same, we can use this equation (5x - 3) • 2.

At first I tried 5, but soon after realized that it wouldn't be enough to make 104, so I doubled the number to 10.

x = 10

((5 • 10) - 3) • 2

(50 -3) • 2

47 • 2 = 94 ( sum of the two equal sides)

94 + 10 = 104

On solving the provided question, we can say that by using N= 2X + 1 or  N = 2X-1  will do the job for composite numbers.

By multiplying two small positive integers, you can create a composite number, which is a positive integer. Likewise, any positive integer that has at least one divisor besides itself and 1. Positive whole numbers make up composite numbers. It lacks prime (that is, it has divisors other than 1 and itself). The first several composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, and are frequently referred to simply as "composites." In other words, composite odd numbers encompass all non-prime odd numbers. for illustration: 9, 15, 21, etc. No. As a result, 2 only possesses the divisors 1 and 2. To put it another way, since 2 only has two divisors, it is not a composite number.

Outliers in regression can be identified by looking for data points that are far away from the overall trend of the data. These points are usually evaluated by calculating the distance from the regression line to the point and comparing it to the standard deviation of the model.

Outliers in regression can be identified by looking for data points that are far away from the overall trend of the data. These points will often have a much larger or smaller value than the rest of the data, so they can be easily spotted by eye. However, to make sure that a point is truly an outlier, it is important to calculate the distance from the regression line to the point and compare it to the standard deviation of the model. If the distance is greater than two or three times the standard deviation, then the point is likely an outlier. Outliers can have a significant effect on the outcome of a regression analysis, so it is important to identify and address them appropriately.

Sample size = 400

Standard error of the mean = 0. 2

Specifically, the size of the random sample, the degrees of freedom, and either the confidence level or the critical t-value.

Assuming that the sample size is large enough  n > 30 and the population standard deviation is unknown,

Use the following formula to estimate the standard deviation of the population from the standard error of the mean,

s = SEM × √(n)

where s is the sample standard deviation,

SEM is the standard error of the mean,

and n is the sample size.

Substituting the given values, we get,
