The maximum number of tickets the theater can sell is 39,572.

The maximum number means the greatest amount of something possible.

The theater sale each weekend is 761 tickets.

There are eight weekend days in a month and in case the month starts with a Saturday or a Sunday there can be an additional weekend.

To calculate the maximum number of tickets the theater can sell in 1 year, we can multiply the maximum number of tickets sold per weekend by the number of weekends in a year, which is 52.

So, 761 tickets x 52 weekends = 39,572 tickets

Therefore, the maximum number of tickets the theater can sell in 1 year is 39,572 tickets.

Answer:

The population standard deviation is a measure of how much variation there is among individual data points in a population. It's a way of quantifying how spread out the data is from its mean.

the cut-off dollar amount for being in the top 3% of patients is approximately $487.32.

To find the cut-off dollar amount for being in the top 3% of patients visiting the emergency room for a sore throat, we need to use the normal distribution with a mean of $320 and a standard deviation of $89.
Find the z-score for the top 3%
To find the z-score, we can use a z-table, which provides the area under the curve of the standard normal distribution. Since we want to find the top 3%, we will look for 0.97 (1 - 0.03) in the z-table. The z-score corresponding to 0.97 is approximately 1.88.
Convert the z-score to a dollar amount
Now that we have the z-score, we need to convert it to a dollar amount using the mean and standard deviation. The formula for this is:
X = μ + (z * σ)
Where X is the dollar amount, μ is the mean ($320), z is the z-score (1.88), and σ is the standard deviation ($89).
Calculate the cut-off dollar amount
Using the formula from Step 2, we can now calculate the cut-off dollar amount:
X = 320 + (1.88 * 89)
X = 320 + 167.32
X ≈ 487.32

Answer:

c 96%

Step-by-step explanation:

The (+2) and (-8) in y = (x + 2)² - 8 shift the graph up two units and down eight units, respectively.

It is called quadratic because the highest degree of the equation is two. This type of equation is used to calculate the roots of a polynomial, which are the values of x where the equation equals 0.

The (+2) in y = (x + 2)² - 8 shifts the graph up two units on the y-axis.

This is because the addition of two to x before squaring it creates a quadratic equation which will create a graph which is two units higher than the graph created by the original equation.

The (-8) in y = (x + 2)² - 8 shifts the graph down eight units on the y-axis. This is because subtracting 8 from the squared term creates a graph which is eight units lower than the graph created by the original equation.

Therefore, the (+2) and (-8) in y = (x + 2)² - 8 shift the graph up two units and down eight units, respectively.

This creates a graph which is six units lower than the graph created by the original equation.

The volume of the rock is 9.5 mL.

What is the volume ?

To find the volume of the rock using water displacement, we need to subtract the initial volume of water (20 mL) from the final volume of water with the rock in the cylinder (29.5 mL). The difference between the two volumes represents the volume of the rock.

Volume of rock = Final volume - Initial volume

Volume of rock = 29.5 mL - 20 mL

Volume of rock = 9.5 mL

Therefore, the volume of the rock is 9.5 mL.

Volume is the amount of space occupied by an object or a substance. It is a three-dimensional quantity that can be measured in units such as cubic meters (m³), cubic centimeters (cm³), liters (L), or milliliters (mL), depending on the size of the object or substance being measured.

The formula for calculating the volume of a simple geometric shape, such as a cube or a sphere, can be found by multiplying the length, width, and height of the object. For more complex shapes, the volume can be calculated using methods such as water displacement, which involves measuring the amount of water displaced by an object when it is submerged in a container of water.

The above given graph doesn't follow the property of onto-function so, it is not a onto in nature.

What about onto-function?

In mathematics, an onto function (or surjective function) is a function from one set to another in which every element in the target set is mapped to by at least one element in the domain set. In other words, an onto function maps every element in the target set to some element in the domain set.

Formally, let f: A → B be a function from set A to set B. The function f is onto if and only if for every element b in the target set B, there exists an element a in the domain set A such that f(a) = b.

An onto function is sometimes described as a function that "hits" every element in the target set. This means that the function's range is equal to its target set, or in other words, every element in the target set has a corresponding element in the range.

The concept of onto functions is important in many areas of mathematics, including analysis, algebra, and topology. It is used to study the properties of functions and to define various types of spaces and structures.

"The beautiful thing about learning is that no one can take it away from you." :)

Answer:24 seconds

Step-by-step explanation:

Since A(t) equals the total number of pixels in the image, then to figure out when it will be zero you just need to set A(t) equal to zero. This gives you the equation

[tex]0=(256-8t)(192-8t)[/tex]

Since this equation equals zero, we know either 256-8t must equal 0 or 192-8t must since they are multiplied.

We can split this into two equations

[tex]256-8t=0[/tex]

[tex]8t=256\\t=32[/tex]

and

[tex]192-8t=0\\8t=192\\t=24[/tex]

So, after 24 and 32 seconds both the width and height equal zero. Only the height or the width need to equal zero for the total area to equal zero (A=w*h), so we go with the lesser time, 24 seconds.

the system of inequalities that represents this situation is: x ≤ 50 , y ≤ 100 , 175 - y ≥ x Let's start by defining some variables:

Let x be the number of single reservations.

Let y be the number of reservations for two or more people.

Since there are 50 single rooms and x single reservations, there must be at least 50 - x double rooms available for reservations for two or more people. Since each of these double rooms can accommodate 2 or more people, the total number of people who can be accommodated in these double rooms is 2(50 - x) = 100 - 2x.

The total number of people who can be accommodated in the hotel is 2x + (100 - 2x) = 100. This means that y, the number of reservations for two or more people, must satisfy the inequality y ≤ 100.

Each reservation for two or more people requires a double room, so the total number of double rooms used for reservations for two or more people is y. Since there are 175 double rooms in the hotel, the number of double rooms available for single reservations is 175 - y. Each single reservation requires one room, so the total number of single rooms used for reservations is x.

Therefore, the system of inequalities that represents this situation is:

x ≤ 50

y ≤ 100

175 - y ≥ x

The first inequality represents the fact that the number of single reservations must be less than or equal to the number of single rooms available. The second inequality represents the fact that the number of reservations for two or more people must be less than or equal to the total number of people who can be accommodated in double rooms. The third inequality represents the fact that the number of double rooms available for single reservations must be greater than or equal to the number of single reservations.

These three inequalities together represent the constraints on the number of single and double rooms that can be used for reservations, and the number of people who can be accommodated in the hotel. Solving this system of inequalities will give us the feasible region of the problem, which will allow us to find the optimal solution

Answer: coin

Step-by-step explanation: because the dice has to many outcomes

Let the first number be x and the second number be y. Then we have:

xy/4 = 10 + 9 + 10

Simplifying the right side:

xy/4 = 29

Multiplying both sides by 4:

xy = 116

Now we need to find two numbers whose product is 116. We can start by listing the factors of 116:

1, 2, 4, 29, 58, 116

Since we are looking for two numbers whose product is 116, we can try pairs of factors until we find a pair that works:

1 x 116 = 116 (not a sum of two numbers)

2 x 58 = 116 (sum is 60, not 19)

4 x 29 = 116 (sum is 33, not 19)

So the only pair that works is:

x = 29 and y = 4

Let's check if these values satisfy the original equation:

xy/4 = 29 x 4 / 4 = 29 = 10 + 9 + 10

So the solution is x = 29 and y = 4.
