The one-time fling! Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party, and then returned the purchase? This is called a one-time fling. About 20% of all adults deliberately do a one-time fling and feel no guilt about it! In a group of nine adult friends, what is the probability of the following?

Answers

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

Translate this sentence into an equation. 32 is the product of Mabel's age and 2 . Use the variable m to represent Mabel's age. URGENT

Answers

m*2=32(this is the equation)
Therefore m=16(Mabel’s age if you wanted)

To translate the given sentence into an equation, use the equation 2m = 32 and then divide both sides by 2 to solve for Mabel's age, which is 16 years old.

The sentence '32 is the product of Mabel's age and 2' can be translated into an equation using the variable m to represent Mabel's age. The product of two numbers means you multiply them together. We are given that when you multiply Mabel's age by 2, you get 32. The equation that represents this relationship is:

2m = 32

To find Mabel's age, we simply divide both sides of the equation by 2 to isolate m, which gives us:

m = 32 / 2

m = 16

Mabel's age is 16 years old.

Answer:

The value of the equation is [tex]x=\frac{y-a}{b}[/tex].

Step-by-step explanation:

Consider the provided equation.

[tex]y=bx+a[/tex]

We need to solve the provided equation for x.

Subtract a from both side.

[tex]y-a=bx+a-a[/tex]

[tex]y-a=bx[/tex]

Divide both sides by b.

[tex]\frac{y-a}{b}=\frac{bx}{b}[/tex]

[tex]x=\frac{y-a}{b}[/tex]

Hence, the value of the equation is [tex]x=\frac{y-a}{b}[/tex].

The variable 'x' as the subject of the formula of the equation y = bx + a is x = ( y - a )/b.

How to make 'x' the subject of the formula of the equation?

Given the equation in the question:

y = bx + a

To make the variable 'x' the subject of the formula of the equationy = bx + a, first isolate term with the variable 'x'.

y = bx + a

To isolate the term containing variable 'x', first subtract 'a' from both sides of the equation:

y - a = bx + a - a

y - a = bx

Reaorder:

bx = y - a

Now, divide both sides by 'b':

bx/b = ( y - a )/b

x = ( y - a )/b

Therefore, the variable 'x' equals ( y - a )/b.

Write a function ℎ(x) to represent the amount of money that Anna earns working as

e. What functions could be combined to represent Anna’s total earnings?
Combine the functions to write an expression that can be used to represent
Anna’s total earnings, where x represents the number of hours she works as a
barista

Answers

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'.

The planets move around the sun in elliptical orbits with the sun at one focus. The point in the orbit at which the planet is closest to the sun is called perihelion, and the point at which it is farthest is called aphelion. These points are the vertices of the orbit. A planet's distance from the sun is 741,000,000 km at perihelion and 817,000,000 km at aphelion. Find an equation for the planet's orbit. (Place the origin at the center of the orbit with the sun on the x-axis. Use the following as necessary: x, y.)

Answers

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]

How to find an equation for the planet's orbit

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.

Three roads lead into a stadium's parking areas. Each road has four lanes (two in each direction) with a capacity oftwo parking attendants are required to park cars for each type a lot, while just one can handle each type b lot. Of the ten lots that will be used tonight, six are type a and four are type b. How many parking attendants are required for tonight's event?1,00vehicles/lane/hour. If 10,000 vehicles are expected for a game, how long will it take for all of them to enter the parking areas?

Answers

Final answer:

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.

Explanation:

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.

an=an−1+1.4 , where a1=4.4

Answers

Answer:

a_n=a_(n−1)+1.4 , where a_1=4.4

Step-by-step explanation:

Given a sequence as

4.4, 5.8, 7.2, 8.6, 10, …

We find that first term is 4.4

II term = 5.8 = 4.4+1.4

III term = 7.2 = 5.8+1.4

Iv term = 8.6 = 7.2+1.4

V term = 10.0 = 8.6+1.4

i.e. each term is got by adding 1.4 to the previous term.

In other words, this is an arithmetic sequence with I term =4.4 and d = common difference =1.4

I term = a_1 = 4.4

and a_2 = a_1+1.4 and so on.

Hence correct answer is

a_n=a_(n−1)+1.4 , where a_1=4.4

Final answer:

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.

Explanation:

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.

Step-by-step explanation:

48x - ky = 11

-48x           -48x

         -ky = -48x + 11

         [tex]\frac{-ky}{-k} = \frac{-48x}{-k} + \frac{11}{-k}[/tex]    

           [tex]y =\frac{48x}{k} - \frac{11}{k}[/tex]

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

 (k + 2)x + 16y = -19

- (k + 2)x             -(k + 2)x

                 16y = -(k + 2)x - 19

                  [tex]\frac{16y}{16} = -\frac{(k + 2)x}{16} - \frac{19}{16}[/tex]

                  [tex]y = -\frac{(k + 2)x}{16} - \frac{19}{16}[/tex]

Slope: [tex]-\frac{(k + 2)}{16}[/tex]

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

[tex]\frac{48}{k}[/tex] and [tex]-\frac{(k + 2)}{16}[/tex] are perpendicular so they have opposite signs and are reciprocals of each other.  When multiplied by its reciprocal, their product equals -1.

[tex]-\frac{(k + 2)}{16}[/tex] *  [tex]\frac{k}{48}[/tex] = -1

[tex]\frac{(k + 2)k}{16(48)}[/tex] = 1

Cross multiply, then solve for the variable.

Answers

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:

what is the domain and range?

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

Answers

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}


Hey there!!

What is a coordinate form?

... Coordinate form is written as ( x , y )

What is domain?

... Domain are also called as the 'x' values.

What is the range?

... Range is the other word for the 'y' values.

Given ordered pairs :-

( 4 , 2 ) ; ( -9 , 2 ) ; ( 5 , 4 ) ; ( 4 , 17 )

Hence, the domain is :-

... { 4 , -9 , 5 )

Hence, the range is :-

...  { 2 , 4 , 17 )

Remember :- The values "can not" be repeated!

Hope my answer helps!!
