In this section we will discuss the method of graphing an equation in two variables. In other words, we will sketch a picture of an equation in two variables.

Step-by-step explanation:

Answer:

The answer can be written in multiple forms

[tex]4 \left(x-2 \right)[/tex]  or   [tex]4x-8[/tex]

Step-by-step explanation:

Given "4 times the difference of x and 2​".

"Times" is multiplication and can be expressed as *

"the difference of x and y" can be expressed as (x -y)

Therefore in this example we can write

[tex]4 \left(x-2 \right)[/tex]

We can leave it as is or simplify it further.

We can simplify it by applying  the distributive property.

Distribute the 4.

[tex](4*x)-(4*2)[/tex]

Answer:

The transformation f(x)↦f(-x) , the graph of f(x) reflects it across the y-axis

Step-by-step explanation:

The correct answer is B) an equation of the best-fit line of data can be used to estimate untested values.

The equation of the best-fit line of data can be calculated by determining the slope (m) and the y-intercept (b) of the line. It is calculated by using the linear regression equation: y = mx + b, where m is the slope and b is the y-intercept. The slope is determined by the equation: m = (Σxy)/(Σx2). The y-intercept is determined by the equation: b = (Σy - mΣx)/n. Once these values are determined, it is possible to estimate untested values with the equation of the best-fit line. For example, if we have a graph with data points (2, 3) and (4, 7), the equation of the best-fit line would be y = 2x + 1. This equation can be used to estimate the value of y when x = 6; in this case, y = 11.

The percentage of players weighing less than or equal to 233 pounds is 88.04%.

Percentage

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

See attachment for box plot,

From the box plot, the maximum is ,

Max = 244

the maximum is.

Min = 152

Percentage less than 233 is calculated as:

percentage = (233 - min)/ max - min

percentage = (233 - 152)/ 244 - 152

percentage = 81/92

express as percentage,

= 81/92 *100

= 8100/92

139.2 cm² is the surface area, in cm², of the figure.

The surface area of a three dimensional shape is the total area of all of the faces. The surface area of a solid object is a measure of the total area that the surface of the object occupies.

here, we have,

The surface area of given figure = 3×Area of rectangle + 2×area of triangle base.

so, we get,

Surface area = 3×6×6+2×15.6

Surface area = 139.2 cm²

Hence, 139.2 cm² is the surface area, in cm², of the figure.

The domain and the range of the function and its inverse is increasing.

In order to use the given linear function to complete the table, we would have to substitute each of the values of x (x-values) into the linear function and then evaluate as follows;

When the value of x = -1, the linear function is given by;

f(x) = 3x + 2

f(-1) = 3(-1) + 2

f(-1) = -1.

When the value of x = -2/3, the linear function is given by;

f(x) = 3x + 2

f(-2/3) = 3(-2/3) + 2

f(-2/3) = 0.

When the value of x = -1/3, the linear function is given by;

f(x) = 3x + 2

f(-1/3) = 3(-1/3) + 2

f(-1/3) = 1.

When the value of x = 1/3, the linear function is given by;

f(x) = 3x + 2

f(1/3) = 3(1/3) + 2

f(1/3) = 3.

When the value of x = -1, the inverse function is given by;

f⁻¹(x) = 1/3(x) - 2/3

f⁻¹(-1) = 1/3(-1) - 2/3

f⁻¹(-1) = -0.9999

When the value of x = 0, the inverse function is given by;

f⁻¹(x) = 1/3(x) - 2/3

f⁻¹(0) = 1/3(0) - 2/3

f⁻¹(0) = -2/3.

When the value of x = 1, the inverse function is given by;

f⁻¹(x) = 1/3(x) - 2/3

f⁻¹(1) = 1/3(1) - 2/3

f⁻¹(1) = -1.

When the value of x = 3, the inverse function is given by;

The experimental probability that Dave works will be in a wedding in next week is 7 / 22.

Actual experiments and sufficient documentation of the occurrence of occurrences serve as the foundation for experimental probability, sometimes referred to as empirical probability. A number of real experiments are carried out in order to ascertain the likelihood of any event. Random experiments are studies that don't have a predetermined outcome. The results of such experiments are unpredictable. The likelihood of random experiments is calculated repeatedly. A trial is a repeating of an experiment that is performed a certain number of times.

The probability that Dave will work in a wedding is given as:

P = Working in wedding / Sum of total work

P = 14 / 44

P = 7 / 22

The perimeter of the triangle is given by the equation P = 42.588 m

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the perimeter of the triangle be represented as P

Let the right triangle be represented as ABC

Now , the hypotenuse of the triangle is AC = 18m

And , the measure of ∠ACB = 30°

From the trigonometric relations ,

Let the angle be θ , such that

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin 30° = AB / 18

On simplifying the equation , we get

Multiply by 18 on both sides of the equation , we get

sin 30° = 1/2

AB = 18/2

The opposite side of the triangle AB = 9 m

Now , the base of the triangle BC is calculated from Pythagoras theorem

hypotenuse² = base² + height²

So , base BC² = ( 18 )² - ( 9 )²

The base of the triangle BC = √ ( 324 - 81 )

The base of the triangle BC = 15.588 m

Now , the perimeter of the triangle P = opposite side of the triangle AB + base of the triangle BC + hypotenuse of the triangle AC

The perimeter of the triangle P = 18 + 9 + 15.588

The perimeter of the triangle P = 42.588 m

Hence , the perimeter of the triangle is 42.588 m

The probability of rolling two sixes is 1/25.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given, the probability of rolling a 6 on a biased dice is 1/5.

Since the probability of rolling a six on the first roll is 1/5, then probability of not rolling a six on first roll is;

P(not 6) = 1 - 1/5

P(not 6) = 4/5

A) Please find attached the completed tree diagram

B) First Roll:

P(6) = 1/5

P(not 6) = 4/5

Second Roll:

Now,

P(6 | 6) = 1/5 × 1/5

= 1/25

P(6 | not 6) = 1/5 × 4/5

= 4/25

So, P(not 6 | 6) = 4/5 × 1/5

= 4/25

P(not 6 | not 6) = 4/5 × 4/5

In correlational and experimental study designs, a key requirement for a sample is that population whom the researchers are investigation

A sample is a portion of a larger population that is selected to represent the entire group. In both correlational and experimental study designs, a key requirement for a sample is that it should be representative of the population it is meant to represent.

In a correlational study design, the goal is to examine the relationship between two or more variables. The sample must be representative of the population to ensure that the correlation calculated from the sample is representative of the correlation that exists in the population.

If the sample is not representative, the correlation calculated from the sample may be different from the correlation that exists in the population, leading to incorrect conclusions.

In an experimental study design, the goal is to test a causal relationship between two or more variables.

The sample must be representative of the population to ensure that the results of the experiment are generalizable to the population.

If the sample is not representative, the results of the experiment may not be generalizable to the population, leading to incorrect conclusions.
