Step-by-step explanation:

A definition for the word domain is the "input" of a function, also called the x values.

A definition for the word range is the "output" of a function, also called the y values.

With this knowledge, looking at the question, it is asking for the range of the relation, which means we are looking at the y values.

A is incorrect because it shows all values from -4 to 4, however some are not in the relation shown.

B is correct because it is showing all of the y values given in the table and no others.

C is incorrect because it is just showing the bounds of the relation, but not all values between.

D is incorrect because it is the domain of the function, or the x values.

Therefore, you were correct, and your answer is B.

Inferential statistics are a better way to interpret the data.

Inferential statistics are regularly used to evaluate the variations among the remedy corporations. Inferential records use measurements from the pattern of topics within side the test to evaluate the remedy corporations and make generalizations approximately the bigger populace of topics.

There are many sorts of inferential records and every is suitable for a selected studies layout and pattern characteristics. Researchers must seek advice from the numerous texts on experimental layout and records to discover the proper statistical take a look at for his or her test. However, maximum inferential records are primarily based totally at the precept that a take a look at-statistic cost is calculated on the premise of a specific formula. That cost together with the levels of freedom, a degree associated with the pattern size, and the rejection standards are used to decide whether or not variations exist among the remedy corporations. The large the pattern size, the much more likely a statistic is to suggest that variations exist among the remedy corporations.

Therefore, we get that inferential statistics are a better way to interpret the data.

The expression is given as:

-5, 6

Ordered pairs are often represented by the parenthesis i.e. ( , )

Where the variables x and y are in the parenthesis

So, the proper representation of an ordered pair is

(x, y)

Substitute -5, 6 for x and y in (x, y)

(-5, 6)

Answer: y=3.75x+1.9

Step-by-step explanation: the pick up fee would be the y-intercept and the per mile cost would be the slope.

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Pick up fee charges = $1.90

Charges per mile = $3.75

Total fare = $80.65

The number of miles traveled = x

We can write an equation as:

1.90 + 3.75x = 80.65

The number of miles traveled:

1.90 + 3.75x = 80.65

Subtract 1.90 on both sides.

1.90 + 3.75x - 1.90 = 80.65 - 1.90

3.75x = 78.75

Divide both sides by 3.75.

x = 21.

Thus,

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

Given information:

Define the variables:

Create two equations from the given information:

[tex]\textsf{Equation 1}: \quad x + y = 84[/tex]

[tex]\textsf{Equation 2}: \quad 25x+9.5y=1046[/tex]

Rewrite Equation 1 to make y the subject:

[tex]\implies y=84-x[/tex]

Substitute this into Equation 2 and solve for x:

[tex]\implies 25x+9.5(84-x)=1046[/tex]

[tex]\implies 25x+798-9.5x=1046[/tex]

[tex]\implies 15.5x+798=1046[/tex]

[tex]\implies 15.5x=248[/tex]

The following statements are true and correct:

Segment EF is twice as long as segment AB

The length of segment AD is 8 units

Since quadrilateral ABCD is scaled to form quadrilateral EFGH, both are similar polygon.

Now, it is known that;

scale factor = ratio of any of their corresponding side

Thus;

Scale factor = GH/CD = 12/6 = 2

This means quadrilateral EFGH is twice the size of quadrilateral ABCD.

The shape of the original polygon remains the same while the size increases.

This implies that, all segments of quadrilateral ABCD increases proportionally times 2 to give us corresponding lengths of the segments of quadrilateral EFGH.

Since shape remains the same, their corresponding angles are congruent and the same in measure.

Therefore, the following statements are true and correct:

Segment EF is twice as long as segment AB; because (EF = AB*scale factor = 3*2 = 6)

The length of segment AD is 8 units because (EH = AD*scale factor = 8*2 = 16)

The critical points are 0, 5 and 9 for the inequality (x² - 9 x) / (x - 5) < 0.

The critical point is a single value at which the function is not differentiable

The inequality is given as:

(x² - 9 x) / (x - 5) < 0.

Factorize the numerator

x (x - 9) / (x - 5) < 0.

Equate it to 0, we get that:

x (x - 9) = 0 or x - 5 = 0

x = 0 or x - 9 = 0 or x - 5 = 0

So, the critical points will be:

x = 0 or x = 9 or x = 5.

Therefore, the critical points are 0, 5 and 9 for the inequality (x² - 9 x) / (x - 5) < 0.

The equation is y = ₋20/x and when x = 3 then y = ₋ 6.6 .

Given x and y vary inversely.

The relationships between variables that are expressed as y = k/x, where x and y are two variables and k is a constant value, are known as inverse variation. According to this statement, if the value of one item rises, the value of the other quantity falls.

the value of x is  = 3, we need to find the value of y.

then when x = 5 and y = ₋4

If y varies inversely as x then:

x × y = k (for some constant c)

If (x,y) = (5,₋4) then:

5 × ₋4 = k

₋20 = k

Therefore, xy = ₋20

then, y = ₋20/x ; is the equation of y.

when x = 3, then:

y = ₋20/3 or y = 6.6

Hence we get the required equation of y and the value of when x = 3 as y=₋20/x and y = ₋20/3 or y = 6.6
