Match The Key Aspect Of A Functions Graph With Its Meaning.

Answers

Answer 1
Final answer:

The key aspect of a function's graph in Mathematics is its ability to visually illustrate relationships, patterns, and comparisons. Different types of graphs, like line, bar, and pie, provide different ways to interpret the data. Understanding these graphs helps in mathematical analysis and solving problems.

Explanation:

The question involves analyzing functions' graphs and matching them with their meanings. In Mathematics, a function's graph can represent different types of information based on its structure. For example, a line graph signifies a linear relationship between two variables denoted on the horizontal and vertical axis. The height of the curve at any point on the graph represents the value of the function at that point.

Three distinct types of graphs are the line, bar, and pie graph. A line graph shows the relationship between two variables with one variable being represented on the horizontal axis and the other on the vertical axis. A bar graph utilises the height of the bars to signify a relationship, with each bar representing a distinct entity like a group of people or a country. A pie graph is used to show how something is distributed, with each slice representing the corresponding percentage of the whole.

Deciphering this information from a graph includes recognizing patterns, comparisons, and trends, providing an intuitive sense of relationships in the data.

Answer 2

Here are the matches: f(x) > 0: Intervals of the domain where the graph is above the x-axis. f(x) < 0: Intervals of the domain where the graph is below the x-axis. Y-intercept: Location on the graph where the output is zero. X-intercept: Location on the graph where the input is zero.

In a function f(x), when f(x) > 0, it indicates the intervals on the domain where the function's values are positive, corresponding to regions above the x-axis. Conversely, when f(x) < 0, it denotes intervals where the function's values are negative, representing areas below the x-axis.

The y-intercept is the point where the graph intersects the y-axis, highlighting where the output (function value) is zero. On the other hand, the x-intercept is where the graph crosses the x-axis, signifying the point where the input (x-value) is zero, resulting in a zero output. These aspects provide valuable insights into a function's behavior and characteristics.

Step-by-step explanation:

A movie rental kiosk has the following options to select from.

Genre: action, romance, comedy, horror, drama

Duration: less than 90 minutes, 90 minutes120 minutes, more than 120 minutes

If employees restock the kiosk by randomly adding movies into it, what is the probability that the next movie added is an action movie that is longer than 120 minutes?

Answers

Answer:

1/20

Step-by-step explanation:

To calculate how many potential combinations of genre and duration, we multiply the number of options in each category.

5 genres * 4 durations = 20 combinations

So for each film placed, there is a 1 in 20 chance that it will be a specific combination.

The probability that the next movie added is an action movie that is longer than 120 minutes is 1/20.

To calculate the probability that the next movie added is an action movie that is longer than 120 minutes, we need to make some assumptions, as the exact numbers of each category are not provided.

If we assume that movies are equally distributed among the different genres and durations, and there are 5 genres and 3 durations, we can conduct a probability calculation.

To calculate the probability that the next movie is an action movie longer than 120 minutes:

Calculate the probability of choosing an action movie, with 5 genres,

the probability is 1/5.

Calculate the probability of the movie being longer than 120 minutes, with 4 durations,

the probability is 1/4.

Multiply these two probabilities to get the combined probability

1/5 × 1/4 = 1/20 or 5%

x = 1/2 (-2a - 2b) = -a - b

y = 1/2 (2c) = c

Midpoint D (-a-b , c)

Answer:  (-a-b, c)

Step-by-step explanation:

We know that the mid point of a line having endpoints [tex](x_1,y_1)[/tex] and  [tex](x_2,y_2)[/tex]  is given by :-

[tex]x=\dfrac{x_1+x_2}{2}\ , \ y=\dfrac{y_1+y_2}{2}[/tex]

In the given figure it can be seen that D is the midpoint of RT :

Since R(-2b , 2c)  and  T(-2a, 0)

Then , the midpoint D of a line having endpoints [tex](-2b,2c)[/tex] and  [tex](-2a,0)[/tex] is given by :-

[tex]x=\dfrac{-2b+(-2a)}{2}=\dfrac{2(-a-b)}{2}=-a-b\ , \ y=\dfrac{2c+0}{2}=c[/tex]

Hence , the coordinates of midpoint D = (-a-b, c)

we know that

[tex](8x+80)=(8x+8(10))[/tex]

Factor the number 8

[tex](8x+8(10))=8(x+10)[/tex]

therefore

The expression factored is [tex]8(x+10)[/tex]

Answer:

The factorization of the given expression is given as:

                                 [tex]8(x+10)[/tex]

Step-by-step explanation:

To factor a algebraic equation means to represent it as the multiplication of the simple expressions.

( i.e. if the expression has a common multiple in each of the terms then we take  it out and represent the rest of the expression in brackets.

Also, we can express a algebraic equation by the multiplication of the factors of the expression )

We are given a expression as:

[tex]8x+80[/tex] which represents  the total amount in the account after 8 months.

and x represents the amount saved each month.

Since both the terms i.e. 8x and 80 have a common multiple as: 8

Hence, we take it out of the expression and write the resulting expression as follows:

[tex]AB = \sqrt {(x2-x1) ^ 2 + (y2-y1) ^ 2}\\AB = \sqrt {(- 5-3) ^ 2 + (- 2-4) ^ 2}\\AB = \sqrt {(- 8) ^ 2 + (- 6) ^ 2}\\AB = \sqrt {64 + 36}\\AB = \sqrt {100}\\AB = 10[/tex]

We have the BC distance:

On May 17th Jane took out a loan for $33,000 at 6% to open her law practice office the loan will mature the following year on January 16th using the ordinary interest method what is the maturity value do on January 16th

Answers

Answer:

$ 31050

Step-by-step explanation:

Step 1 : Write the formula for calculating simple interest.

Simple Interest = P x R x T

                                100

P: Principal Amount-The loan taken (30,000)

R: Interest rate at which the loan is give (6)

T: Time period of the loan in years-there are 12 months in 1 year. There are 7 months from May till June (7/12)

Step 2: Substitute values in the formula

Simple Interest = 30,000 x 6 x 7/12

                                       100

Simple Interest = $1050

Step 3: Calculate the amount due at maturity

At the maturity or the end of the time period given, the original or principal amount of the loan has to be repaid along with the simple interest.

Amount at maturity = Principal Amount + Simple Interet

Amount at maturity = 30,000 + 1050

Amount at maturity = $31050

Two fair dice, one yellow and one blue, are rolled. The value of the blue die is subtracted from the value of the yellow die. Which of the following best describes the theoretical probability distribution?

A) constant
B) symmetric
C) positively skewed
D) negatively skewed

Answers

Answer:

B) symmetric

Step-by-step explanation:

We will find the sample space for rolling two dices first

Here first value in ordered pair represents yellow die and second represents blue die

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

The subtraction gives us:

0 , -1 , -2, -3, -4, -5, 1, 0, -1, -2, -3, -4, 2, 1, 0, -1, -2, -3, 3, 2, 1, 0, -1, -2, 4, 3, 2, 1, 0, -2, 5, 4, 3, 2, 1, 0

So the distribution will be as follows:

X      5       4       3       2        1        0        -1       -2      -3       -4      -5

P(X)  1/36  2/36  3/36 4/36  5/36  6/36  5/36  4/36  3/36  2/36  1/36

By observing the probabilities, we can conclude that the distribution will be symmetric

Hence, Option B is correct ..

6) If an equilateral triangle has equal angles, then all its angles will measure 45°.

Answers

Answer:

1) If 3 is an odd number, then 3 times 3 is an even number.

False because multiplying odd number by an odd number also gives an odd number.

2) If 6 is less than 7, then 4 is greater than 7.

False because 4 is smaller than 6. As 6 is smaller than 7 then 4 must also be smaller.

3) Six is divisible by 3, and 10 is a multiple of 2.

True. 6/3 = 2 and 2 x 5 = 10. Both the conditions are true so it is also true.

4) The average of the data is greater than the largest value in the data, or it’s less than the largest value in the data.

True.

We have two conditions in this statement and an 'or' between them. One of the conditions is true that is "average is less than the largest value in the data". So the statement as a whole is true.

5) The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.

True.

6) If an equilateral triangle has equal angles, then all its angles will measure 45°.

False.

A triangle has 3 angles whose sum = 180 degrees.

For equilateral triangle each angle will measure 180/3= 60 degrees.

Answer:  2 following statements are true

The first true statement:

Six is divisible by 3, and 10 is a multiple of 2.

We know this because 6 is divisible by 3, and again proven by when we  divide 10 by 5 we get 2, so 10 is a multiple of 2.

The second true statement:

The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.

Step-by-step explanation:

A double-blind study is a study where neither participants nor experimenters know which subjects are receiving the treatment.

This method is really useful to minimize possible biased conclusions about the experiment.

Therefore, the right answer is C, the situation described refers to a double-blind study.

A double-blind study is an experimental design in which both the subjects and experimenters are unaware of the treatment or control group assignments, thereby reducing bias and increasing the reliability of the study's findings.Therefore, the correct answer is option C.

An experiment where neither the subjects nor the experimenters know which subjects are in the treatment or control group is best described as a double-blind study.

This type of research design is crucial to prevent biases from affecting the outcome of clinical trials or other medical studies. In a double-blind study, both the participants and researchers are 'blind' to the assignments, thereby reducing the risk of placebo effects or experimenter bias influencing the results.

Experiments in the field of medicine often use this design to test the efficacy of new drugs, treatments, or interventions in the most unbiased way possible.

A control group that receives a placebo is essential in these experiments to compare the actual efficacy of the experimental treatment against no treatment or a standard treatment.

Answer:  [tex]y=\frac{1}{30}x+1[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

You need to find slope of the line with the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Pick to  points of the given line. You can choose the point (60,3) and the point (30,2).

Then, substituting into the formula:

 [tex]m=\frac{2-3}{30-60}=\frac{1}{30}[/tex]

You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:

What is the area of a triangle?

The area of a triangle is 1/2 × b × h sq. units

where b - base and h - height the triangle.

Calculating the volume:

It is given that a triangular pyramid has a triangular base with

base length b = 4 inches

height of the triangle h = 1.5 inches and

height of the pyramid = 9 inches

So, the volume of the pyramid = 1/3 × B × h

Where base area B = 1/2 × b × h

⇒ B = 1/2 × 4 × 1.5

       = 3.0 sq. inches

And the volume = 1/3 × 3.0 × 9

                             = 9 cubic inches.

           

Therefore, the volume of the given triangular pyramid is 9 cubic inches.

Sanjay solved the equation below. Which property did he use to determine that 7x+42=42 is equivalent to
7(x+6)=42
7x+42=42
7x=0
x=0

Answers

Step-by-step explanation:

7(x + 6) = 42

distributive property:  a(b + c) = ab + ac

(7)(x) + (7)(6) = 42

7x + 42 = 42

subtraction property of equality  (subtract 42 from both sides)

7x + 42 - 42 = 42 - 42

7x = 0

division property of equality   (divide both sides by 7)

7x : 7 = 0 : 7

x = 0

Answer:

1. Distributive property: a(b + c) = a.b + a.c

2. Property of subtraction of equality

3. Property of division of equality

Step-by-step explanation:

The given equation is 7x + 42 = 42

7(x+6)=42    [Distributive property: a(b + c) = a.b + a.c]

7x+42=42   [Property of subtraction of equality]

Subtract 42 from both sides.

7x + 42 - 42 = 42 - 42

7x=0  

Property of division of equality

Divide both sides by 7.
