or **1/3 hour per table**, if she spends an equal amount of time at each table.

Yolana can serve a total of 36 people if she has to serve 9 tables, each of which can hold 4 guests, and she must serve a total of 4 guests per table.

How long does each visitor spend on average?

We need to know the entire length of time Yolana will spend serving all 36 guests in order to calculate the average time spent per guest.

If the entire time is divided by the number of guests,we get:

36 people in 3 hours equals 5 minutes each person.

Thus, each visitor spends 5 minutes on average.

What is the average time?

A measurement of a set of time values' central tendency is the average time. It is determined by multiplying the total number of values in the set by the sum of all the time values.

As an illustration, if you have a series of times of 5, 10, and 15, you would add them all up to reach 30 minutes, divide that number by 3, and get an average time of 10 minutes.

Answer: We can solve this system of equations by substituting the expression for y in terms of x from the second equation into the first equation, and then solving for x.

First, we substitute y = 2 + x from the second equation into the first equation, giving:

2x - 3(2 + x) = -5

Simplifying this expression by distributing the -3, we get:

2x - 6 - 3x = -5

Combining like terms, we get:

-x - 6 = -5

Adding 6 to both sides, we get:

-x = 1

Multiplying both sides by -1, we get:

x = -1

Therefore, the value of x in the system of equations is -1.

Step-by-step explanation:

Represent the three even numbers as 2x, 2y, 2z, where x,y,z are integers.

2x+2y+2z = 108

x+y+z = 54

Let x≤y≤z

x = z/2

y = ¾z

z/2 + 3z/4 + z = 54

2z/4 + 3z/4 + 4z/4 = 54

2z + 3z + 4z = 216

9z = 216

z = 24

x = z/2 = 12

y  = ¾z = 18

Therefore, The numbers are 24, 36, 48.

After answering the presented question, we can conclude that Yet, we equation cannot make final decisions based just on the median.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the value "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

Whether data is sorted in ascending or descending order, the median is the midway value. In this situation, the median sales amount for Company A is $7,000, which suggests that half of the sales are greater than $7,000 and half are less. The median sales amount for Business B is $6,000, which means that half of the sales are greater than $6,000 and half are less.

The median can be a useful approach to summaries a data set's core tendency. For example, we can see that Company A has a greater median sales amount than Company B, implying that Company A generates more money each sale on average. Yet, we cannot make final decisions based just on the median.

The solution of the given problem of percentage comes out to be  $19,000 in 12 years, they should deposit $170.89 at the conclusion of each quarter.

The abbreviation "a%" is used to indicate a value or number in statistics that is expressed as a percentage of 100. Versions with "pct," "pct," or "pc" as the initials are also rare. However, the most popular method to do this is to use the percentage symbol ("%"). Additionally, both hints nor a constant ratio of every element to the overall amount exist. Since numbers commonly add up to 100, they are essentially integers.

Here,

=>  [tex]FV = PMT * [(1 + r/n)^(n*t) - 1] / (r/n)[/tex].

By entering these numbers, we obtain:

[tex]= > 19000 = PMT * [(1 + 0.07/4)^(4*12) - 1] / (0.07/4)[/tex]

Upon solving for PMT, we obtain:

[tex]= > PMT = 19000 * (0.07/4) / [(1 + 0.07/4)^(4*12) - 1][/tex]

=> PMT = $174.58 (rounded to the nearest cent)

In order to have $19,000 in 12 years, the investor needs to deposit $174.58 at the conclusion of each quarter at a rate of 7% compounded quarterly.

(b) Using the same procedures as in (a), but with an interest rate of 7.2%, we arrive at:

[tex]= > 19000 = PMT * [(1 + 0.072/4)^(4*12) - 1] / (0.072/4)[/tex]

Upon solving for PMT, we obtain:

[tex]= > PMT = 19000 * (0.072/4) / [(1 + 0.072/4)^(4*12) - 1][/tex]

=>  PMT = $170.89 (rounded to the nearest cent)

Let's start by using the information given to find the total number of books in each library:

For Library A, we know that 30 comic books are 2% of its total books. So, we can set up the following equation:

 30 = 0.02x

where x is the total number of books in Library A. Solving for x, we get:

 x = 1500

Therefore, Library A has a total of 1500 books.

For Library B, we know that 45 comic books are 5% of its total books. So, we can set up the following equation:

 45 = 0.05x

where x is the total number of books in Library B. Solving for x, we get:

 x = 900

Therefore, Library B has a total of 900 books.

For Library C, we know that 65 comic books are 2% of its total books. So, we can set up the following equation:

 65 = 0.02x

where x is the total number of books in Library C. Solving for x, we get:

 x = 3250

Therefore, Library C has a total of 3250 books.

For Library D, we know that 75 comic books are 10% of its total books. So, we can set up the following equation:

 75 = 0.1x

where x is the total number of books in Library D. Solving for x, we get:

 x = 750

Therefore, Library D has a total of 750 books.

For Library E, we know that 90 comic books are 3% of its total books. So, we can set up the following equation:

 90 = 0.03x

where x is the total number of books in Library E. Solving for x, we get:

 x = 3000

Therefore, Library E has a total of 3000 books.

Now that we have the total number of books in each library, we can rank them based on the number of comic books they have:

Library C: 65 comic books

Library E: 90 comic books

Library B: 45 comic books

Library A: 30 comic books

Library D: 75 comic books

Therefore, the libraries ranked from 1 having the greatest total number of comic books to 5 having the least total number of comic books are: C, E, B, A, D.
