False. A data set may have one mode, but it is also possible for a data set to have no mode or multiple modes.

A mode of data is defined as an observation with the highest frequency among the values that appear most frequently in the given data.

If no value is repeated, the dataset has no mode. If two or more values appear with the same maximum frequency, then the dataset has multiple modes.

For example, consider the following dataset:

1, 2, 3, 3, 4, 4, 5

In this dataset, both 3 and 4 appear twice, which means that the dataset has multiple modes.

So, in general, it is not always true that a data set will have exactly one mode. It depends on the values in the dataset and their frequencies.

Therefore, the correct answer would be option (B) False.

The statement that a speech that was made to persuade people can also inform or entertain the audience, is A. True.

A persuasive speech is one that is given with the intention of convincing the audience to hold a certain belief or behave in a particular way. This includes a wide range of activities like voting, organ donation, recycling, and more.

A powerful persuasive speech convinces the audience to agree with your point of view by establishing your credibility and subject-matter expertise.

Persuasive speaking is particularly listener-centered since the speaker must, in a sense, meet the audience halfway. It is obvious that the speaker cannot totally control the process because persuasion occurs when the listener concurs with what the speaker says. Because of this, effective speaking requires particular attention to audience study.

Therefore, a persuasive speech would also serve to inform or amuse the audience.

Independent variable and dependent variable

What occurs as a result of the independent variable is referred to as a dependent variable.

We anticipate that independent variables will have an impact on dependent variables.

Eg. You plan a study to see if variations in the room's temperature have an impact on students' math test results.

The inside temperature of the space is your independent variable. By making the room cooler for half the participants and warmer for the other half, you can change the temperature.

Test results in mathematics are your dependent variable. Using a standardised test, you measure each participant's math prowess to see if there are any temperature-related differences.

Answer:

Step-by-step explanation:

The solution of the equation is "True for all value of x".

In the given question, two boats are traveling in a canal in opposite directions, where x represents the distance, in feet, between the boats.

The equation 4(x + 1) = 4x + 4 models the paths of the boats.

We have to solve for x.

The equation is 4(x + 1) = 4x + 4

Using the Distributive property

4x + 4 = 4x + 4

Subtract 4 on both side, we get

4x = 4x

Subtract 4x on both side, we get

0 = 0

As we can see that the equation is true for all the value of x.

The two boats are traveling exactly 0 feet apart in the canal.

The equation 4(x + 1) = 4x + 4 can be rearranged to solve for x. First, subtract 4x from both sides of the equation so that the equation becomes 4(x + 1) - 4x = 4x + 4 - 4x. This simplifies to 4 + 4x = 4, and when 4 is subtracted from both sides of the equation, the result is 4x = 0. To solve for x, divide both sides of the equation by 4, so that x = 0.

This means that the two boats are traveling exactly 0 feet apart in the canal.

Considering the expression of a line, the equation of the line that passes through the pair of points (35, -30) and (-12, 34) is y=-4/3x +18.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of said line can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope and the value of one of the points in the expression of a line, the value of the ordinate to the origin can be obtained.

In this case, being (x₁, y₁)= (36, -30) and (x₂, y₂)= (-12, 34), the slope m can be calculated as:

m= (34 - (-30))÷ (-12 - 36)

m= (34+30)÷ (-12 - 36)

m= 64÷ (-48)

m= -4/3

Considering point 2 and the slope m, you obtain:

34= -4/3×(-12) + b

34= 16 +b

34 -16= b

18= b

Answer:

[tex]\dfrac{10}{7}[/tex]

Step-by-step explanation:

To solve this problem, we first have to understand some exponent rules.

1. When an exponent is a fraction, the exponent's numerator is how many instances of the base there are, and its denominator is the root of those instances.

For example,

[tex]5^{2/3} = \sqrt[3]{5^2} = \sqrt[3]{25}[/tex]

2. When an exponent is negative, the resulting value is reciprocated.

For example,

[tex]3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{9}[/tex]

Using these rules, we can rewrite the given expression.

[tex]\left(\dfrac{49}{100}\right)^{-1/2} = \dfrac{1}{\sqrt{\dfrac{49}{100}}}[/tex]

Then, we can simplify the denominator by solving for the square root of the  fraction 49/100.

[tex]\dfrac{1}{\sqrt{\dfrac{49}{100}}} = \dfrac{1}{\dfrac{7}{10}}[/tex]

Finally, we can apply the fraction division rule.

[tex]A \div \dfrac{B}{C} = A \times \dfrac{C}{B}[/tex]

[tex]\dfrac{1}{\dfrac{7}{10}} = 1 \cdot \dfrac{10}{7} = \dfrac{10}{7}[/tex]

All the possible values of each expression is given as an inequality as;

0 < a - b < -1

We are given the inequalities of the domain and range as;

3 < a < 4

4 < b < 5

Thus, we can say that the maximum value of a - b will be the difference between the maximum value of a and the minimum value of b to give;

(a - b)max = 4 - 4

(a - b)max = 0

Similarly, minimum value of a - b will be the difference between the maximum value of b and the minimum value of a to give;

(a - b)min = 4 - 5

(a - b)min = -1

Thus, all possible values would be expressed as;

The value of unknown v from the given equation 8v - 4(v + 8) = 8 is

v = 10.

Simplifying the given algebraic equation :

8v - 4(v + 8) = 8

Rearrange the terms in equation :

8v - 4(8 + v) = 8

8v - (8 * 4 + v * 4) = 8

8v - (32 + 4v) = 8

Expand and rearrange the terms:
