find the median of 2,2,2,3,4,5,6,7,8,9​

The discount that she receives in total is 12 dollars.

Factors are integers (whole numbers) greater than 1 that are multiplied together to produce a given product.

The expression 4x-12 can be factored to (4x - 4) - (4-8).

This means that the discount that Lauren receives on each book is 4 dollars. So, for each book, the price is reduced by 4 dollars.

This means that if the original price of each book is x dollars, then Lauren pays x-4 dollars for each book.

In total, she pays 4(x-4) = 4x-16 dollars for 4 books.

This means that the discount that she receives in total is 12 dollars.

Therefore, we can conclude that Lauren receives a 4 dollar discount on each book she purchases and a total discount of 12 dollars when she purchases four books.

The value of [tex]$\tan A$[/tex] in its simplest radical form is [tex]8/3$.[/tex]

What is radical form?

Radical form refers to a mathematical expression that includes radicals, which are symbols that indicate a root of a number.

To find the value of [tex]$\tan A$[/tex], we first need to determine the value of [tex]\cos A$.[/tex]

Using the Pythagorean identity, we have:

[tex]$$\sin^2 A + \cos^2 A = 1$$[/tex]

Substituting the given value of [tex]$\sin A$[/tex], we get:

[tex]$$\left(\frac{8}{\sqrt{73}}\right)^2 + \cos^2 A = 1$$[/tex]

Simplifying the left-hand side, we get:

[tex]$\frac{64}{73} + \cos^2 A = 1$$$$\cos^2 A = \frac{9}{73}$$$$\cos A = \frac{3}{\sqrt{73}}$$[/tex]

Since angle [tex]$A$[/tex] is in the first quadrant, both [tex]$\sin A$[/tex] and [tex]$\cos A$[/tex] are positive.

Therefore, we have:

[tex]$$\tan A = \frac{\sin A}{\cos A} = \frac{8/\sqrt{73}}{3/\sqrt{73}} = \frac{8}{3}$$[/tex]

So the value of [tex]$\tan A$[/tex] in its simplest form is [tex]8/3$.[/tex]

In equation h=3.25w+19, the number 3.25 represents the rate of change in the height of the sunflower per week (w), and the constant term of 19 represents the initial height of the sunflower when it was first planted.

The equation h=3.25w+19 is in slope-intercept form, which means that it can be written as y=mx+b, where y represents the dependent variable (in this case, the height of the sunflower), x represents the independent variable (the number of weeks since the sunflower was planted), m represents the slope of the line, and b represents the y-intercept (the value of y when x=0).

In this equation, the slope is 3.25, which means that for each additional week that passes since the sunflower was planted, its height increases by an average of 3.25 inches. So, the number 3.25 represents the rate of change of the height of the sunflower with respect to time.

This means that for every additional week that passes since the sunflower was planted, the height of the sunflower increases by 3.25 inches on average.

Step-by-step explanation:

10(5x + 12) = 2(5x + 15)  Distribute the 10 and the 2

10(5x) + 10(12)  = 2(5x) + 2(15)

We can solve [tex]2^{a}[/tex] x[tex]2^{b}[/tex]  = [tex]2^{0}[/tex] by recognizing that [tex]2^{0}[/tex]equals 1 and simplifying the equation to [tex]2^{a+b}[/tex] = 1.

To solve [tex]2^{a}.2^{b}=2^{0}[/tex] for a and b, we must first recognize that 2^0 equals 1, which means that the equation can be rewritten as [tex]2^{a}.2^{b}=1[/tex]. Therefore, we can simplify the equation to [tex]2^{a+b}[/tex] = 1.

Since 2 raised to any negative power is a fraction, we need at least one of the exponents to be negative.

We could also choose other values that make either a or b negative, such as a = -2 and b = 2, or a = -3 and b = 3. The key is to have one negative exponent and one positive exponent so that their sum equals zero.

In summary, we can solve [tex]2^{a}.2^{b}=1[/tex]by recognizing that [tex]2^{0}[/tex] equals 1 and simplifying the equation to [tex]2^{a+b}[/tex] = 1. We must have at least one negative exponent to satisfy the equation, and we can choose various values for a and b as long as their sum equals zero.

The proof involves showing that the bisecting line QS and the parallel sides QR and PS create pairs of congruent angles, which then proves that opposite sides are parallel. Therefore, PQRS is a parallelogram.

Proof:

Since QS bisects PR at T, we know that PT = RT and QT = TS.

Also, QR is parallel to PS. Therefore, angle QTS is congruent to angle RPT (alternate interior angles).

Using the same reasoning, we can show that angle PST is congruent to angle QRP (alternate interior angles).

Now, we have two pairs of congruent angles in the quadrilateral PQRS, which means that the opposite sides are parallel.

The Cauchy Integral Formula (Generalized version), we have: ∫C [tex]z^2[/tex] dz = ∫C[tex]z^2[/tex]/(z - 0) dz

To apply the Cauchy-Goursat Theorem, we need to check if the function f(z) is analytic inside the contour C, i.e., it should be differentiable everywhere inside C.

(a) Let f(z) =[tex]ze^(-z)[/tex]. Then, f(z) is entire, i.e., differentiable everywhere in the complex plane. Hence, it is analytic inside the unit circle C. Now, applying the Cauchy-Goursat Theorem, we have:

∮C f(z) dz = 0

(b) Let f(z) = 2. Since 2 is a constant, it is analytic everywhere in the complex plane. Hence, it is analytic inside the unit circle C. Now, applying the Cauchy-Goursat Theorem, we have:

∮C f(z) dz = f(0) × 2πi = 0 (since C does not enclose the origin)

(c) Let f(z) = z tan(2π/2). Since tan(2π/2) is not analytic at z = ±i, f(z) is not analytic inside the unit circle C. Hence, we cannot apply the Cauchy-Goursat Theorem directly to evaluate the integral ∮C f(z) dz.

To evaluate the integral ∮C f(z) dz, we can use the Cauchy Integral Formula (Generalized version) which states that for any analytic function f(z) and any closed contour C, we have:

∮C f(z)/(z - a) dz = 2πi f(a)

where a is any point inside the contour C.

For (a), let's use the Cauchy Integral Formula to evaluate the integral. We have:

f(z) = z[tex]e^{-z[/tex]

∮C f(z) dz = ∮C f(z)/(z - 0) dz (since f(0) = 0)

= 2πi f(0) = 0

For (b), we can use the Cauchy-Goursat Theorem as f(z) = 2 is analytic everywhere inside the circle |z| = 4. Hence, we have:

∮C2 dz = 2πi f(0) = 2πi × 2 = 4πi

For (c), we need to use the Cauchy Integral Formula to evaluate the integral. We have:

f(z) = z tan(π/2)

∮C f(z) dz = ∮C f(z)/(z - i) dz (since i is inside C)

= 2πi f(i) = 2πi × i × tan(π/2) = -2πi

Thus, we have:

∮C f(z) dz ≠ ∮C f(z) dz in general.

Now, let C be the positively oriented boundary of the square whose sides lie along x = ±2 and y = ±2.

(a) Using the Cauchy Integral Formula (Generalized version), we have:

∫C cos(z) dz = ∫C cos(z)/(z - π/2) dz

= 2πi cos(π/2) = 0

(b) Using the Cauchy Integral Formula (Generalized version), we have:

∫C cosh(z) dz = ∫C cosh(z)/(z - 0) dz

= 2πi cosh(0) = 2πi

(c) Using the Cauchy Integral Formula (Generalized version), we have:

the linear equations that have an infinite number of solutions are (x – 3/7) = 2/3 (3/2x – 9/14), 3x – 18 = 3(–6 + 4.1).

To determine which linear equations have an infinite number of solutions, we need to check if the equations are equivalent. Two linear equations are equivalent if they have the same slope and y-intercept, or if they represent the same line.

Let's check each of the given equations:

(x – 3/7) = 2/3 (3/2x – 9/14)

Multiplying both sides by 14, we get:

14x - 6 = 28/3x - 6

Multiplying both sides by 3, we get:

42x - 18 = 28x - 18

Subtracting 28x and adding 18 to both sides, we get:

14x = 0

Dividing both sides by 14, we get:

x = 0

Substituting x = 0 into the original equation, we get:

(-3/7) = (-9/14)

The left-hand side is equal to the right-hand side, which means the equation is true for all values of x. Therefore, this equation has an infinite number of solutions.

8(x + 2) = 5x – 14

Expanding the left-hand side, we get:

8x + 16 = 5x - 14

Subtracting 5x and subtracting 16 from both sides, we get:

3x = -30

Dividing both sides by 3, we get:

x = -10

Substituting x = -10 into the original equation, we get:

8(-8) = 5(-10) - 14

-64 = -64

The left-hand side is equal to the right-hand side, which means the equation is true for x = -10. Therefore, this equation has exactly one solution.

3x – 18 = 3(–6 + 4.1x)

Expanding the right-hand side, we get:

3x - 18 = -18 + 12.3x

Subtracting 3x and adding 18 to both sides, we get:

0 = 0.3x

Dividing both sides by 0.3, we get:

x = 0

Substituting x = 0 into the original equation, we get:

-18 = -18

The left-hand side is equal to the right-hand side, which means the equation is true for all values of x. Therefore, this equation has an infinite number of solutions.

1/2(6x + 10) = 7(3/7x – 2)

Expanding both sides, we get:

3x + 5 = 3x - 14

This equation simplifies to 5 = -14, which is not true for any value of x. Therefore, this equation has no solutions.

2x – 3.5 = 2.1(5x + 8)

Expanding the right-hand side, we get:

2x - 3.5 = 10.5x + 16.8

Subtracting 2x and adding 3.5 to both sides, we get:

0 = 8.5x + 20.3

This equation simplifies to 0 = 0, which is true for all values of x. Therefore, this equation has an infinite number of solutions.

Therefore, the linear equations that have an infinite number of solutions are (x – 3/7) = 2/3 (3/2x – 9/14), 3x – 18 = 3(–6 + 4.1).

-6r -6r

7d -9d = -44

d = -44/2

d = -22

6r + (-22) = 226

6r = 248

r = 248/6

r = 41

Each regular pizza costs $41, and each deluxe pizza costs $22.

The system of equations given consisted of two equations, both of which represented the cost of the pizzas ordered by the two customers, Karen and Malik. To solve this system of equations, we first subtracted 6r from both equations, leaving us with 7d and -9d on one side. We then divided both sides by -2, leaving us with d = -22. We then added 22 to the other equation, leaving us with 6r = 248. Finally, we divided both sides by 6, leaving us with r = 41. Thus, each regular pizza costs $41 and each deluxe pizza costs $22.

Each data point's ones digit is displayed in the second column, while its tens digit is displayed in the first column. Each "1|1" in the key denotes the value "11" in the data collection.

The term "statistical data" refers to numerical data that is gathered from a sample or population in order to characterise or draw conclusions about a larger group. Observational studies, surveys, experiments, and other techniques can all be used to gather statistical data, as can data from already-existing records and databases. Many approaches and methodologies, including data visualisation, inferential statistics, and descriptive statistics, can be used to examine statistical data. Measures of central tendency (mean, median, mode), indicators of dispersion (standard deviation, range, interquartile range), and graphical representations are some examples of the key characteristics of a dataset that are summarised and described using descriptive statistics (histograms, box plots, scatter plots). A bigger population can be inferred from a sample of data using inferential statistics, on the other hand.

La tabla representa una función exponencial, ya que la razón entre los términos consecutivos es constante y no varía como en una función lineal.

This gives a result of t = 10, meaning that it will take 10 days for the amount of money in the box to be reduced to 25 cents.

If there are R125 in a box and half of the total is removed each day, it will take 10 days to reduce the total to 25 cents. This is because the total amount is being halved each day, and the amount remaining at the end of each day is the amount left at the start of the day, divided by two. This can be expressed mathematically using the formula[tex]R125/(2^t)[/tex] = 25, where t is the number of days.If we solve the equation for t, we get t = log2(R125/25). This gives a result of t = 10, meaning that it will take 10 days for the amount of money in the box to be reduced to 25 cents.To calculate this process over the 10 days, we can use the formula [tex]R125/(2^t)[/tex] for each day, where t is the day number. Starting at day 0, the amount remaining would be R125. At the end of day 1, the amount remaining would be R125/2 = R62.50. At the end of day 2, the amount remaining would be R62.50/2 = R31.25. This process continues until at the end of day 10, the amount remaining would be R0.25.
