The mark-up for the playground slides is 170%. The mark-up refers to the price added to the cost to find out the selling price of a product.

Mark-up is the difference between the selling price and cost price of a product.It is usually represented as a percentage, the mark-up percentage is calculated over the cost of the product. In other words we can say that mark-up is the profit gained from selling a particular product. Here it is said that the cost of a playground slide is $290 and the selling price of the playground slide is $783. We need to find the mark-up percentage of the playground slide.

Mark-up %=[tex]\frac{selling price-cost}{cost}[/tex]×100=[tex]\frac{783-290}{290}[/tex]x100=[tex]\frac{493}{290}[/tex]x100=170%

Therefore the mark-up percentage of the playground slide is 170%.

Answer:

y = 14.5x + 5

Step-by-step explanation:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Order of 4 tickets has a price of $63

Order of 6 tickets has a price of $92

2. Write an equation to find the price of any amount of tickets.

Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:

Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2

Price of a ticket = (92 - 63)/2

Price of a ticket = 29/2 = 14.50

If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.

Order of 4 tickets - Price of 4 tickets = Service or delivery fee

Replacing, we have:

63 - 58 = 5

Order of 6 tickets - Price of 6 tickets = Service or delivery fee

Replacing, we have:

92 - 87 = 5

Now, we can write the equation to find the price of an order of any amount of tickets, this way:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

The Roster form of { 8,12,16 } is {X;X=4k ,k ∈ (2,34)}

Roster form:

A set's roster notation is a straightforward mathematical representation of the set. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, each pair of elements is separated by a comma symbol. Because the enumeration is done one by one, the roster form is also known as the enumeration notation.

Given a set in a set builder form i.e.{ 8,12,16 } and asked to convert into  Roster form

Roster form of { 8,12,16 } ={X;X=4k, k ∈ (2,34)}

Therefore,The Roster form of { 8,12,16 } is {X;X=4k, k∈ (2,34)}

The value of (f-g)(x) is 2x³ + 7x²-7x-3.

As we know that, the composition of functions is the criteria of combining two or more functions into a single function. A function represents some work. The combination of two or more function always results in a new function.

Given that, f(x) = 2x³ + 7x² - 4x - 5 and g(x) = 3x - 2 and we have to calculate the value of  (f - g)(x).

Suppose h(x) =  (f - g)(x)

Now, we simply have to solve (f - g)(x), let's proceed to solve

=  (f - g)(x)

= f(x)-g(x)

= 2x³ + 7x² - 4x - 5-(3x-2)

= 2x³ + 7x² - 4x - 5-3x+2

= 2x³ + 7x²-7x-3

h(x) = (f - g)(x) = 2x³ + 7x²-7x-3

∴ (f - g)(x) = 2x³ + 7x²-7x-3

Step-by-step explanation:

The temperature in Celsius will be 25.5556 °C and he temperature in degree Fahrenheit will be 105.8 °F, respectively.

A function assigns the value of each element of one set to the other specific element of another set.

Given the function to convert temperature from Celsius to Fahrenheit is F=(9/5)C+32.

A.) Given that If the temperature is 78 degrees Fahrenheit. Therefore, the temperature in degree Celsius will be,

F = (9/5)C + 32

78 = (9/5)C + 32

78 - 32 = (9/5)C

46 = (9/5)C

C = (46 × 5)/9

C = 25.5556

Hence, the temperature in Celsius will be 25.5556 °C.

B.) Given that  the temperature is 41 degrees Celsius. Therefore, the temperature in degree Celsius will be,

F = (9/5)C + 32

F = (9/5)41 + 32

F = 73.8 + 32

F = 105.8

Hence, the temperature in degree Fahrenheit will be 105.8 °F.

This means x = 2, y = 3 and z = 1

========================================================

Work Shown:

Double everything in the second equation to get 4x-2y+4z=6

Add this result to the first equation

[tex]x+2y-4z = 4\\4x-2y+4z = 6\\5x+0y+0z = 10[/tex]

The first two lines of that expression above shows us adding x+2y-4z=4 to the equation 4x-2y+4z = 6

The x terms add to x+4x = 5x

The y terms add to 2y+(-2y) = 0y

The z terms add to -4z+4z = 0z

The terms on the right hand side add to 4+6 = 10

That's how we end up with the new equation 5x+0y+0z = 10

That becomes 5x = 10 which solves to x = 2 when we divide both sides by 5.

------------------------

Use this x value in the third original equation to find z

3x-8z = -2

3(2)-8z = -2

6-8z = -2

-8z = -2-6

-8z = -8

z = -8/(-8)

z = 1

------------------------

Use the x and z values we found to find y

x+2y-4z = 4

2+2y-4(1) = 4

2+2y-4 = 4

2y-2 = 4

2y = 4+2

2y = 6

y = 6/2

y = 3

----------------------

Overall we get the solutions to be x = 2, y = 3 and z = 1

We can say the solution as an ordered triple is (x,y,z) = (2,3,1)

Step-by-step explanation:

((14×3) + 1 )/3 = (43/3)

14 1/3 can be expressed as 43/3, which is an improper fraction.

To rewrite 14 1/3 as an improper fraction, we need to convert the mixed number into a fraction.

First, we multiply the whole number (14) by the denominator of the fraction (3) and add the numerator (1). This gives us the numerator of the improper fraction. The denominator remains the same.

14 × 3 = 42

Next, we add the numerator (1) to the result we obtained above.

42 + 1 = 43

Therefore, the improper fraction equivalent to 14 1/3 is 43/3.

In the fraction 43/3, the numerator (43) represents the total number of parts we have, and the denominator (3) represents the size of each part. It indicates that we have 43 equal parts of size 1/3.

Answer:

1. Couples tickets: $8

   Individual tickets: $4

2. Song download cost: $2

    Movie download cost: $15

Step-by-step explanation:

You can solve both of these questions by doing system of equations.

Let's start with question 1.

There are 2 variables in this equation:

- Couples tickets price: let's represent these with the letter C

- Individual tickets price: let's represent these with the letter K

Writing the two equations would look this these:

5c + 2k = 48

3c + 2k = 32

Next, isolate a variable. I am going to isolate K in the first equation.

[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]

Now that we isolated a variable we can plug that back in to the second equation:

[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]

We found that c is equal to 8 so we can put that back in to an equation to solve for k.

5(8) + 2k = 48

40 + 2k = 48

2k = 8

k = 4

Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.

Check #1:

5(8) + 2(4) = 48

40 + 8 = 48

48 = 48

3(8) + 2(4) = 32

24 + 8 = 32

32 + 32

Now, let's go on to question 2.

There are 2 variables in this equation:

- Price of songs downloaded: let's represent these with S

- Price of movies downloaded: let's represent these with M

Writing the two equations would look like this:

15s + 11m = 195

15s + 8m = 150

There is a simple way to answer this system, however.

If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:

15s + 11m = 195

-(15s +8m = 150)

Minus them to get this equation:

3m = 45

Solve

m = 15

We have found that each movie download costs $15, now let's plug this back into an equation:

15s + 11(15) = 195

15s + 165 = 195

15s = 30

s = 2

Each song costs $2 to download.

Check #2:

15(2) + 11(15) = 195

30 + 165 = 195

195 = 195

15(2) + 8(15) = 150

30 + 120 = 150

150 = 150

Answer:

(48.65, 56.83)

Step-by-step explanation:

Given that :

Sample size (n) = 40

Mean (m) = 52.74

Standard deviation (s) = 13.21

α = 95%

Confidence interval around sample mean can be obtained using the relation :

Mean ± Zstatistic * s/√n

Z score for 95% confidence interval = 1.96 (Z probability calculator)

s / √n = 13.21 / √40 = 2.0886843

Lower limit of confidence interval :

52.74 - (1.96 * 2.0886843) = 48.646178772 = 48.65

Upper limit of confidence interval :

52.74 + (1.96 * 2.0886843) = 56.833821228 = 56.83
