Assuming that Richard always reads with the same rate, there is a direct proportion between the time spent reading and the portion of book read:

[tex] \text{portion}_1 : \text{time}_1 = \text{portion}_2 : \text{time}_2 [/tex]

So, we can set up and solve the following proportion:

[tex] \dfrac{1}{4} : \dfrac{4}{5} = x : 1 \iff x = \dfrac{\frac{1}{4}}{\frac{4}{5}} = \dfrac{1}{4}\cdot \dfrac{5}{4} = \dfrac{5}{16} [/tex]

It is a function.  It passes the vertical line test, meaning for each x there's at most one y.

When x=2 we see y=-3 as (2,-3) is a point on the graph

The question's subject is about interpreting and representing data using different types of graphs. Each type of graph is chosen based on what we want to show with our data. For instance, line graphs are useful for displaying change over time.

The question refers to the use of graphs to illustrate data. These graphs represent the position of a moving object plotted against time. In the presented case, Part A of the graph begins with a nonzero y-intercept with a downward slope that levels off at zero, while Part B begins at zero with an upward slope that decreases in magnitude until the curve levels off.

When creating graphs, it's important to label the axes correctly and, if multiple datasets are shown on one graph, various symbols should be used to differentiate between them. In the example given, three types of graphs can be used: a line graph to show change over time, a bar graph to compare different categories, and a pie chart to represent proportions. The choice of graph depends on the type of data and what you want to show.

As mentioned, a graphing utility allows us to compare trajectories, highlighting the differences and similarities. It is crucial to use that visualization and analysis tool to make effective interpretations.

x       =       30

Answer: x = 30

For this case we have the following variables:

A: Represents the number of adults

S: Represents the number of students

C: Represents the number of children

For the income we have:

[tex]22A + 15S + 13.50C = 7840[/tex] -----> (1)

Regarding the number of people at the concert we have:

[tex]A + S + C = 400[/tex] -----> (2)

If there are 40 more children than students, we have:

[tex]C = 40 + S[/tex] -----> (3)

We substitute C in the second equation and it remains:

[tex]A + S + 40 + S = 400[/tex]

[tex]A + 40 + 2S = 400[/tex]

[tex]A + 2S = 400-40[/tex]

[tex]A + 2S = 360[/tex]

[tex]A = 360-2S[/tex] --------> (4)

Substituting (3) and (4) in (1) we have:

[tex]22 (360-2S) + 15S + 13.50 (40 + S) = 7840[/tex]

[tex]7920-44S + 15S + 540 + 13.50S = 7840[/tex]

[tex]7920-7840 + 540 = 44S-15S-13.50S[/tex]

[tex]620 = 15.50S[/tex]

[tex]S = \frac{620}{15.50}[/tex]

[tex]S = 40[/tex]

So, there are 40 children.

Substituting S in (3) and obtaining C:

[tex]C = 40 + S[/tex]

[tex]C = 40 + 40[/tex]

[tex]C = 80[/tex]

Substituting S in (4):

[tex]A = 360-2 (40)\\A = 360-80\\A = 280[/tex]

Thus, 280 tickets of adults, 80 of children and 40 of students were sold.

Answer: [tex]2\frac{3}{20}[/tex]

Step-by-step explanation:

First, convert mixed numbers into improper fractions and simplify all fractions

[tex]\frac{4}{10}[/tex] ÷ [tex]\frac{2}{2}[/tex] = [tex]\frac{2}{5}[/tex]

[tex]1\frac{6}{8}[/tex] = [tex]\frac{8(1) + 6}{8}[/tex] = [tex]\frac{14}{8}[/tex] ÷ [tex]\frac{2}{2}[/tex] = [tex]\frac{7}{4}[/tex]

Next, find their sum.  Remember to find the LCD and convert the fractions so they have like denominators.

Monday + Tuesday = Total

[tex]\frac{2}{5}[/tex] + [tex]\frac{7}{4}[/tex] = Total      the LCD of 5 and 4 is 20

[tex](\frac{4}{4})\frac{2}{5}[/tex] + [tex](\frac{5}{5})\frac{7}{4}[/tex] = Total

[tex]\frac{8}{20}[/tex] + [tex]\frac{35}{20}[/tex] = Total

[tex]\frac{43}{20}[/tex] = Total

Then, convert the improper fraction into a mixed number

[tex]\frac{43}{20}[/tex] = [tex]2\frac{3}{20}[/tex]

Answer:

The answer is A and B.

Step-by-step explanation:

They cannot be expressed as a ratio of two integers.

Explanation:

Anna gets paid $8.75/hour working as a barista.

She gets paid $9.00/hour for creating weekly advertisement signs.

In total she works 25 hours a week.

Let 'x' represent the number of hours that she works as a barista, then [tex]25-x[/tex] would represent the number of hours she works to create signs.

A. We need to write a function h(x) that represents the amount of money that Anna earns working as a barista.

Since she is earning $8.75 per hour and she works as a barista for 'x' hours a week so the function is:

[tex]h(x)=8.75\times x=8.75x[/tex]

[tex]h(x)=8.75x[/tex]

B. We need to write a function f(x) to represent the hours Anna works creating the signs.

Since, in total she works for 25 hours a week so the function to represent the number of hours she work to create signs can be given by:

[tex]f(x)=(25-x)[/tex]

C. If 's' represents the number of hours that Anna works creating signs, we need to create a function g(s) that represents her earning creating signs.

So the number of hours Anna works creating signs for the coffee break is [tex]s[/tex], she gets paid $9.00 an hour for creating signs, so:

[tex]g(s)=9\times s=9s[/tex]

[tex]g(s)=9s[/tex]

D. We need to finf a composite function [tex]g(f(x))[/tex], to find the desired function we need to plug value of f(x) in the function g(s):

[tex]g(f(x))=9s=9(f(x))=9(25-x)=225-9x[/tex]

[tex]g(f(x))=225-9x[/tex]

The composite function g(f(x)) represents Anna's earnings while working just to create signs for the Coffee break.

E. To represent Anna's total earnings the functions that can be combined are h(x) and g(f(x)) because h(x) represents Anna's earnings while working as a barista and g(f(x)) represents Anna's earnings while she creates signs for the coffee break.

The function to represent Anna's total earnings can be given as:

[tex]T(x)=h(x)+g(f(x))=8.50x+225-9x[/tex]

where we must keep in mind that 'x' represents the number of hours she spent working as a barista in a 'week'.

Where A ⇒ area of the base

            h ⇒ vertical height of the pyramid.

∴ Volume = (1/3) Ah

                 = 1/3 (229 × 229) × 146

                 = 1/3 × 52,441 × 146

                  = 1/3 × 7,656,386

                = 2,552,128.667 m³

In whole number = 2,552,129 m³

Hi there!

To calculate a discount or a mark-up in the price of a retail item, you need to multiply the given price of the item by the percentage, like so:

1.35 × 0.2 = 0.27

Then you add or subtract as necessary. In your case you would subtract since you are trying to find a discount price.

1.35 - 0.27 = 1.08

So the final price of the product after the discount is $1.08

Given that about 20% of adults do one time fling.

That is probability of a person doing fling is [tex]\frac{20}{100}=0.2[/tex] . Let it be p.

Then we have to use binomial distribution formula for the given problems.

b(x;n,p)=[tex]n_{C_{x}}p^{x}(1-p)^{n-x}[/tex]

A)Probability of no one has done one time fling means x is 0 here.

Hence [tex]b(0;9,0.2)=9_{C_{0} }(0.2)^{0}(1-0.2)^{9}[/tex]

                                   [tex]=1X1X0.8^{9}=0.1342[/tex]

b) Probability of at least one person has done fling=1-(probability of no one has done)

                                                                                    =1-0.1342=0.8658

c)Probability of no more than two people have done one time fling means we need to add the probabilities for x=1,x=2 along with x=0.

[tex]b(1;9,0.2)=9_{C_{1}}(0.2)^{1}(1-0.2)^{8}[/tex]

                     [tex]=9X0.2X0.8^{8}=0.302[/tex]

[tex]b(2;9,0.2)=9_{C_{2}}0.2^{2}(1-0.2)^{7}[/tex]

                      [tex]=36X0.04X0.8^{7}=0.302[/tex]

Hence probability = 0.1342+0.302+0.302 = 0.7382

An even function is when f(x) = f(-x) ... or ... g(x) = g(-x).

f(x) = - (x + 1)(x - 4)

     = -(x² - 3x - 4)

     = -x² + 3x + 4                  f(x) = -x² + 3x + 4

f(-x) = -(-x)² + 3(-x) + 4

      = -x² - 3x + 4                 f(-x) = -x² - 3x + 4

                            f(x) ≠ f(-x) so it is NOT even.

********************************************************

g(x) = [tex]\frac{3}{2}|x|[/tex]

g(-x) = [tex]\frac{3}{2}|-x|[/tex]

       =  [tex]\frac{3}{2}|x|[/tex]  since absolute value becomes positive

g(x) = g(-x) so it IS even

In this scenario, the combined capacity of the three roads leading to the stadium is 12,000 vehicles per hour. Therefore, to park 10,000 vehicles, it would take approximately 50 minutes.

The question involves an understanding of traffic flow and rates. To find the total capacity of these roads leading to the stadium, we multiply the number of roads by the number of lanes on each road and the capacity of each lane, resulting in 4 lanes per road x 3 roads x 1,000 vehicles per lane per hour, equal to 12,000 vehicles per hour.

With 10,000 vehicles expected for the game, we can then divide the total number of vehicles by the total capacity of the roads per hour to find out how many hours it will take for all vehicles to enter the parking lots. Therefore, it will take approximately 10,000 vehicles / 12,000 vehicles per hour = 0.83 hours, or about 50 minutes.

The increased traffic due to a new manufacturing plant, increased businesses, and route changes in the nearby streets can also affect the traffic flow, however these factors are not quantified in the question. In the real world, proper planning and infrastructure can solve campus parking issues, as the example mentioned about Twelfth and Locust Streets.

Answer:

Domain = {4,-9,5}

Range = {2,4,17}

Step-by-step explanation:

We are given ordered pairs as

{(4,2), (-9,2), (5,4), (4,17)}

This is a subset of cartesian product AXB where

A = {4,-9,5} and B = {2,4,17}

Note: Repeated values are written only once in the set.

Hence we find that 4 is mapped on to 2 and 17,

-9 to 2 and 5 to 4

Domain = I item in the ordered pair of mapping =  {4,-9,5}

Range = II item in the ordered pair of mapping =  {2,4,17}

Answer:

The shape of planetary orbits follows from the observed fact that the force of gravity between two objects depends on the square of the distance between them. ... Ellipses are closed so the planets we see in elliptical orbits stick around.

Step-by-step explanation:

We can write the equation for the planet's orbit:[tex]\[ \frac{x^2}{(817,000,000)^2} + \frac{y^2}{(741,000,000)^2} = 1 \][/tex]

To find an equation for the planet's orbit, we can use the properties of an ellipse. The standard form of the equation for an ellipse with its center at the origin and major and minor axes along the x and y-axes is:

[tex]\[ \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \][/tex]

In your problem, the distances at perihelion and aphelion are given as 741,000,000 km and 817,000,000 km, respectively. These distances represent the values of \(a\) and \(b\) in our equation.

So, we have:

[tex]\[ a = 817,000,000 \text{ km} \][/tex]

[tex]\[ b = 741,000,000 \text{ km} \][/tex]

Now, we can write the equation for the planet's orbit:

[tex]\[ \frac{x^2}{(817,000,000)^2} + \frac{y^2}{(741,000,000)^2} = 1 \][/tex]

This is the equation for the planet's elliptical orbit with the sun at one of the foci, where the origin is at the center of the orbit.

Answer:

Not independent.

Step-by-step explanation:

Given that P(A)=0.25 , P(B)=0.2 , and P(A and B)=0.04

To check whether A and B are independent.

Two events are independent if

P(A/B) = P(A) or P(B/A) = P(B) or P(AB) = P(A) P(B)

if any one of the above three is true also, the two events would be independent.

Let us find out first one

P(A/B ) = P(AB)/P(B) (as per conditional probability formula)

= 0.04/0.2=0.2

But P(A) = 0.25 and not equals P(A/B)

Hence we can conclude that A and B are not independent

because P(A/B) not equals P(A)
