What is the system of equations?

A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.

Let's start by defining some variables:

Let b be the price of a balcony ticket

Let f be the price of a general admission floor ticket

We can set up a system of two equations based on the information given in the problem:

77b + 69f = 5,883 (equation 1 for Friday's show)

75b + 69f = 5,775 (equation 2 for Saturday's show)

We can use either substitution or elimination to solve for b and f. Let's use elimination by subtracting equation 2 from equation 1:

(77b + 69f) - (75b + 69f) = 5,883 - 5,775

2b = 108

b = 54

Now that we know the price of a balcony ticket is $54, we can substitute this value into either equation to solve for f. Let's use equation 1:

77(54) + 69f = 5,883

4,158 + 69f = 5,883

69f = 1,725

f = 25

Therefore, the price of a general admission floor ticket is $25.

The answer is:

minimum value = √121/11 = 2/11

maximum value = √17/11

Here's how to solve it:

The given function is c(z) = √z, and the domain interval is 121 ≤ z ≤ 17.

The minimum value of the function occurs at the endpoint of the domain interval where the function takes the smallest value. In this case, the smallest value of the function occurs at z = 17, so the minimum value of the function is:

c(17) = √17

The maximum value of the function occurs at the endpoint of the domain interval where the function takes the largest value. In this case, the largest value of the function occurs at z = 121, so the maximum value of the function is:

c(121) = √121 = 11

Therefore, the minimum value of the function is √17 and the maximum value of the function is 11/√121, which simplifies to 1/11.

Step-by-step explanation:

Distance formula to find distance from O to Q is sqrt (306)

Distance from R to P = sqrt (34)

Diagonals ( found above) intersect at right triangles in a rhombus

  so you can break it into two right triangles of base = sqrt (306)

           and height sqrt (34)/2

    TWO triangles of area = 1/2 base * height

         TOTAL Area is then :     TWO * 1/2 ( sqrt(34)/2)* sqrt (306) = 51 units^2

Answer:

The median is 6.

If you need the mean, mode, range, minimum, maximum, count n, or sum they are

Mean- 6.6666666666667

Mode- 1,3,4,5,6,7,8,12,14

Min- 1

Max- 14

Count n- 9

Sum- 60

Answer:

5.5

Step-by-step explanation:

The median is the middle number in a sorted list of numbers.

Therefore, the first step to solving this problem is sorting this list of numbers from least to greatest:

1, 2, 3, 4, 5, 6, 7, 8, 12, 14

To find the middle number, start by crossing out a number from each side. In this case, the first two numbers to cross out are 1 and 14. 1 is the smallest number in the list and 14 is the greatest. Our list should then look like this:

2, 3, 4, 5, 6, 7, 8, 12

Now, cross out the next smallest and largest numbers of the list (2, 12):

3, 4, 5, 6, 7, 8

The next (3, 8):

4, 5, 6, 7

The next (4, 7):

5, 6

Now we are left with two numbers. When this happens, to figure out the middle number, we have to find the average of these last two remaining digits. The average can be found by adding these two digits and dividing that by the total number of digits you used to add.

In this case, we have 2 numbers left: 5 and 6

1. Add 5 and 6: 5+6=11

2. We used 2 numbers for the addition which means we have to divide 11 by 2: 11/2

Answer:

the measure of the angle is 43.4 degrees, and the measure of its supplementary angle is 180 - 43.4 = 136.6 degrees.

Step-by-step explanation:

Let x be the measure of the angle in degrees.

By definition, supplementary angles add up to 180 degrees, so the measure of the supplementary angle is 180 - x degrees.

According to the problem, the angle measures 136.6 degrees less than the supplementary angle, so we can write:

x = (180 - x) - 136.6

Simplifying the right-hand side, we get:

x = 43.4

Therefore, the measure of the angle is 43.4 degrees, and the measure of its supplementary angle is 180 - 43.4 = 136.6 degrees.

Fiinding and interpreting the zero of a rational function involves solving for x when the function equals zero and understanding its significance within the context.

Hello! I understand you want to find and interpret the zero of a rational function, and I'd be happy to help.

The zero of a rational function occurs when the function's value is equal to zero. In other words, a zero is a value of x that makes the function f(x) = 0. To find the zero, you must set the numerator of the rational function equal to zero and solve for x.

It's important to note that the denominator should never equal zero, as this would make the function undefined.

Interpreting the zero helps us understand the behavior of the function and can be useful in various applications.

For instance, the zero might represent a break-even point in a business context or an equilibrium in a physical system. Whether the result makes sense within the context of a specific problem depends on the given scenario and the mathematical relationship between the variables.

To summarize,  Always ensure the denominator is never zero to maintain the function's validity.

In conclusion you put down 12.5% of the total cost of the home.

How to solve and what is percentage?

To find the percentage you put down on the home, you need to divide the amount you put down (the down payment) by the total cost of the home, and then multiply by 100 to convert to a percentage.

The down payment was $8,000 and the total cost of the home was $64,000.

So the percentage you put down is:

($8,000 / $64,000) x 100% = 12.5%

Therefore, you put down 12.5% of the total cost of the home.

Percentage is a way of expressing a proportion or fraction as a portion of 100. It is denoted by the symbol %, and is often used to express a fraction of a quantity relative to the whole quantity.

Perimeter of pool A is 90ft

Perimeter is a measurement of the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.

For example, the perimeter of a rectangle can be calculated by adding up the length of all four sides of the rectangle. If a rectangle has a length of 6 units and a width of 4 units, its perimeter would be:

Perimeter = 2 x (length + width) = 2 x (6 + 4) = 20 units

To find: Perimeter of A

For Pool B;

Perimeter=120ft

Width=20ft and length=l

Hence, Perimeter of Pool B=2(l+w)

120=2(l+20)

60-20=l

l=40ft

Length of pool A=length of pool B=40

width of pool A=1/4width of pool B

1/4×20=width of pool B

In mathematics, average refers tο a measure that represents the central οr typical value οf a set οf numbers. There are several types οf averages, including mean, median, and mοde.

The mean, alsο called the arithmetic mean, is the sum οf all the numbers in a set divided by the tοtal number οf values in the set. It is the mοst cοmmοnly used type οf average.

Tο find the average rate οf change οf f frοm z = -7 tο z = 6, we need tο calculate the change in f οver the change in z and then take the average.

First, we calculate f(6) and f(-7):

f(6) = 72² + 3(6) + 3

We would need to survey at least 600 randomly selected air passengers to be 90% confident that the sample percentage is within 1.5 percentage points of the true population percentage.

As a number out of 100, a percentage is a technique to express a fraction or a proportion. The sign "%" stands in for the word "percent," which is a contraction of "per hundred."

To determine the sample size for the survey, we can use the following formula:

n = [tex](Z^2 * p * q) / E^2[/tex]

Where:

n is the required sample size

Z is the Z-value for the desired confidence level (in this case, Z = 1.645 for a 90% confidence level)

p is the estimated population proportion (we don't know this yet, so we will assume a conservative estimate of 0.5)

q is the complementary probability of p (q = 1 - p)

E is the maximum error or margin of error (in this case, E = 0.015)

Plugging in the values, we get:

n = ([tex]1.645^2[/tex] * 0.5 * 0.5) / [tex]0.015^2[/tex]

n = 599.27

Rounding up to the nearest whole number, we get a required sample size of 600.

Answer:

Without any measurements, it is not possible to give a numerical estimate for the real height of the lamp post in metres. However, we can use the scale of the drawing to make an estimate.

Let's assume that the scale of the drawing is 1 centimetre (cm) represents 0.5 metres (m) in real life. This means that every 1 cm in the drawing represents 0.5 m in real life.

If we measure the height of the lamp post in the drawing and find that it is approximately 15 cm, we can estimate the real height of the lamp post as follows:

Real height of lamp post = (15 cm) x (0.5 m/1 cm) = 7.5 m

Therefore, using our estimated scale of the drawing, we can estimate that the real height of the lamp post is around 7.5 metres. However, this estimate is only as accurate as the assumptions we made about the scale of the drawing.

Step-by-step explanation:

With 90% cοnfidence, we can say that the true prοpοrtiοn οf custοmers whο cοnsider this market mοre pleasing than the οther stοre is between 0.601 and 0.685. In οther wοrds, we can be 90% cοnfident that the pοpulatiοn prοpοrtiοn οf custοmers whο prefer this market is within this range.

Percentage is a way οf expressing a number οr prοpοrtiοn as a fractiοn οf 100. It is represented by the symbοl "%".

Tο calculate the cοnfidence interval tο estimate the true prοpοrtiοn οf custοmers whο cοnsider this market mοre pleasing than the οther stοre with 90% cοnfidence, we need tο check the fοllοwing cοnditiοns:

In this scenariο, we can assume that the fοrms were distributed randοmly tο the custοmers, and the independence cοnditiοn is met because the respοnses οf οne custοmer dο nοt affect the respοnses οf anοther custοmer. Tο check the sample size cοnditiοn, we can calculate the expected number οf successes and failures in the sample:

Expected number of successes: n * p = 429 * (276/429) ≈ 277

Expected number of failures: n * (1 - p) = 429 * (1 - 276/429) ≈ 152

Both the expected number of successes and failures are greater than 10, so the sample size condition is met.

Now, we can calculate the confidence interval using the formula:

CI = p ± sqrt(p(1-p)/n)

where p is the sample proportion, n is the sample size, and z is the z-score corresponding to the desired confidence level.

In this case, p = 276/429 ≈ 0.643, n = 429, and z = 1.645 (from a standard normal table for 90% confidence level).

Plugging in these values, we get:

CI = 0.643 ± 1.645sqrt(0.643(1-0.643)/429) ≈ (0.601, 0.685)

Therefore, with 90% confidence, we can say that the true proportion of customers who consider this market more pleasing than the other store is between 0.601 and 0.685. In other words, we can be 90% confident that the population proportion of customers who prefer this market is within this range.
