A graph of this sine function f(x) = 2sin3(x − 2π) + 1 is shown below.

The graph of f⁻¹(x) will have a domain of: C. −1 ≤ x ≤ 3.

In this exercise, we would use an online graphing tool plot the given sine function f(x) = 2sin3(x − 2π) + 1 on a graph as shown in the image attached below.

In order to determine the inverse of this sine function, we would have to swap (interchange) both the independent value (x-value) and dependent value (y-value) as follows;

f(x) = y = 2sin3(x − 2π) + 1

x = 2sin3(y − 2π) + 1

x - 1 = 2sin3(y − 2π)

(x - 1)/2 = sin3(y − 2π)

\(\frac{sin^{-1}(\frac{x\;-\;1}{2} )}{3} =y-2 \pi\\\\f^{-1}(x) = \frac{sin^{-1}(\frac{x\;-\;1}{2} )}{3} +2 \pi\)

By critically observing the graph of f⁻¹(x) shown below, we can logically deduce the following domain:

Domain = [-1, 3] or −1 ≤ x ≤ 3.

Answer:

y - 3 = -(x + 1)

y - 3 = -x - 1

y = -x + 2

Answer:

Pick options, 1,2,3,4 but DO NOT select option 5!!!

Step-by-step explanation:

The basic equation is y=mx+b where slope is m and b is the y intercept.

So our y intercept for this equation is 2. The line has a negative slope bc as increases, y decreases. (The line is pointing down.) Those are two good clues to start.

Let's calc the slope. slope = rise/run = (y2-y1)/(x2-x1)

(-1,3) and (1,1) are shown on the graph

slope = (3-1)/(-1-1)

= 2/-2 = -1

Slope = -1

Our equation is now y=-x+2

So let's find everything that equals y=-x+2

y-3 = -x-1 is the same as

y = -x+2

So pick the first option, y-3 = -x-1

(y+1) = -(x-3)

y+1 = -x+3

y=-x+2

So pick the 2nd option, (y+1) = -(x-3)

(y-3) = -(x+1)

y-3 = -x-1

y=-x-1+3

y=-x+2

So pick the 3rd option, (y-3) = -(x+1)

We already know to pick the 4th option, y=-x+2

(y-3) = (x-1)

y= x-1+3

y=x-2

DON'T PICK THE 5th option, because this has the wrong slope and wrong intercept!

To calculate the probability that none of the five randomly selected adults own a car, we need to use the concept of independent events.

Since the probability of an individual owning a car is 76%, the probability of an individual not owning a car is 100% - 76% = 24%. Now, we can calculate the probability of none of the five adults owning a car by multiplying the probabilities of each individual not owning a car, assuming independence.

P(none owning a car) = (0.24) ^ 5 = 0.00173 ≈ 0.17%.

Therefore, the correct answer is not one of the options provided. The closest option is 0.33%, but the correct probability is approximately 0.17%.

Answer: Slope = -3/4

Step-by-step explanation:

Background information

The given equation [y = -3/4x + 2] is in the form of slope-intercept form of linear equation.

The slope-intercept form of a linear equation is where one side contains just [y]. So, it will look like: y = mx + b where [m] is the slope and [b] is the y-intercept.

Match the given equation with the base form of the equation

y = (-3/4)x + 2

y = m x + b

Finalize the match result

m = -3/4

b = 2

Therefore, the slope of the equation [y = -3/4x + 2] is \(\boxed{-\frac{3}{4} }\)

Use the concept of a triangle is defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

In the given figure,

Interior angle = 79°

And the corresponding exterior angle = b

If we combine both angles,

Then it becomes a complete angle of the line.

Since we know that,

The complete angle of a line = 180 degrees.

Therefore,

79° + b =  180°

Subtract 79° on both sides,

b = 101°

Hence,

I. L = 78 metros

II. W = 34 metros.

Step-by-step explanation:

Sabemos que un campo deportivo tiene forma rectangular.

Dados los siguientes datos;

Perímetro del rectángulo = 224 m

Traduciendo el problema verbal a una expresión algebraica, tenemos;

W = ⅓L + 8 = L/3 + 8

Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;

P = 2 (largo + ancho)

Sustituyendo en la ecuación, tenemos;

224 = 2(L + [L/3 + 8])

224 = 2L + 2L/3 + 16

Reordenando la ecuación (recolectando términos semejantes), tenemos;

224 - 16 = 2L + 2L/3

224 - 16 = 8L/3

208 = 8L/3

Multiplicación cruzada, tenemos;

8L = 208 * 3

8L = 624

L = 624/8

L = 78 metros

Para encontrar el ancho;

W = L/3 + 8

W = 78/3 + 8

W = 26 + 8

W = 34 metros.

Answer:

Step-by-step explanation:

The given data can be presented as follows;

\(\begin{array}{ccc}x&&y\\2&\leftrightarrow &1\\3&\leftrightarrow &4\\4&\leftrightarrow &6\\5&\leftrightarrow &7\\6&\leftrightarrow &6\\7&\leftrightarrow &3\\8&\leftrightarrow &2\\9&\leftrightarrow &1\\10&\leftrightarrow &1\end{array}\)

We find the sum of the data points as follows;

n = 1 + 4 + 6 + 7 + 6 + 3 + 2 + 1 + 1 = 31

The median will be located in the (n + 1)/2 th data point

Therefore the median is the (31 + 1)/2 = 16th data point

The sum of the first three bars on the histogram = 11

The sum of the first four bars on the histogram = 18

Therefore, the 16th data point is located in the fourth bar which has x value of 5

The median is therefore, C. 5

Answer:

Option B

v – 13 = 3

v – 13 + 13 = 3 + 13

v = 16

Thus, The value of v is 16

-TheUnknownScientist 72

Solution:

\(4(v - 13) = 12\\ (4 \times v) + (4 \times -13) = 12\\ 4v - 52 = 12\\ 4v = 12 + 52\\ 4v = 64\\v = \frac{64}{4} = 16\)

Bayes' theorem is a fundamental concept in probability theory and statistics that provides a way to update or revise probability estimates based on new or additional information.

It is named after the English statistician Thomas Bayes, who first formulated the theorem in the 18th century. Bayes' theorem is widely used in various fields such as science, engineering, medicine, finance, and artificial intelligence.

It is an essential tool for solving problems related to decision making, prediction, and classification.

Bayes' theorem is based on conditional probability, which describes the probability of an event given that another event has occurred. The theorem provides a formula for calculating conditional probabilities and allows for the incorporation of new information or evidence into the probability estimate.
