Small pizzas = 21

Large pizzas = 39

Step-by-step explanation:

The number of small pizzas sold be x

So, the number of large pizzas sold be 2x - 3

And the total value is $640.504

Now the equation would be

$14.50x + $9 × (2x - 3) = $640.50

$14.50x + 18x - $27 = $640.50

$32.50 = $640.50 + $27

$32.50x = $667.50

x = 21

If the standard deviation of a set of data is 6, then the value of variance is 36

The formula for determining variance is variance = √Standard deviation

Variance of a set of data is equal to square of the standard deviation.

If the standard deviation of a set of data is 6 then we get variance by putting the value of standard deviation in the formula

variance = √Standard deviation

Take square root on both sides

Standard deviation² = 6²

Standard deviation= 36

Hence,  standard deviation of a set of data is 6, then the value of variance is 36

Step-by-step explanation:

The equation that can be used to find the cost of shipping boxes is: 3p + 11 = 34.70. By solving the equation, we get p = $7.23.

The problem is about finding the cost of shipping boxes. Ava purchased 3 flat-rate shipping boxes, and a book of stamps, spending a total of $34.70. The problem asks to find out how much the post office charged for each shipping box, given that the cost of a book of stamps is $11.

To find the cost of a single flat-rate shipping box, let's assume that the post office charged p dollars for each shipping box. Therefore, the cost of three shipping boxes will be 3p dollars.

Along with this, Ava also bought a book of stamps which cost her $11.

So, the total amount she spent can be written as the sum of the cost of the shipping boxes and the cost of the book of stamps. This is given by:

3p + 11 = 34.70

Solving for p, we get:

p = (34.70 - 11)/3p = $7.23 (approx)

Therefore, each shipping box costs $7.23.

The ramp will rise from the ground at its highest end to a height of approximately 8.56 inches. Rounded to the nearest hundredth of an inch, this is 8.56 inches.

Fiberboard is a type of engineered wood product that is made by combining wood fibers or other plant-based fibers with a binder or adhesive, and then compressing and heating the mixture to create a dense, flat panel

We can use trigonometry to solve this problem. Let's call the height of the ramp "h" and the length of the base "b". We want to find "h".

First, we need to find "b". We know that the fiberboard is 27 inches long, so the base of the ramp will be the length of the hypotenuse of a right triangle. Using trigonometry, we can find:

b = 27 * cos(19°) ≈ 25.68 inches

Next, we can use trigonometry again to find "h". We know that the angle of elevation from the ground is 19°, so the angle of depression from the ramp to the ground is also 19°. This means we have a right triangle with the height "h", the base "b", and an angle of 19°. Using trigonometry, we can find:

tan(19°) = h/b

Solving for "h", we get:

h = b * tan(19°) ≈ 8.56 inches

Therefore, the ramp will rise from the ground at its highest end to a height of approximately 8.56 inches. Rounded to the nearest hundredth of an inch, this is 8.56 inches.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.

The closest percent markup cost to the bracelets Anna sells is 181%.

To determine the percent markup cost for the bracelets Anna sells, we need to calculate the difference between the selling price and the cost price, and then express it as a percentage of the cost price.

The selling price of the bracelets is $45, and the cost price is $16.

Markup = Selling Price - Cost Price

= $45 - $16

= $29

Now, to calculate the percent markup cost, we divide the markup by the cost price and multiply by 100:

Percent Markup Cost = (Markup / Cost Price) \(\times\) 100

= ($29 / $16) \(\times\) 100

= 181.25

Rounded to the nearest whole number, the percent markup cost is approximately 181%.

Therefore, the closest percent markup cost to the bracelets Anna sells is 181%.

This means that Anna is charging customers approximately 181% more than what it cost her to make the bracelets.

The markup cost represents the additional amount she adds to cover expenses, overhead, and to make a profit.

Given statement solution :- The star would cross the observer's meridian (the imaginary line running from the North celestial pole through the observer's zenith to the South celestial pole) exactly halfway between rising and setting. As the Earth rotates, this would take roughly 12 hours to complete.

The number of hours a star is above the horizon depends on several factors, including the star's declination (angular distance north or south of the celestial equator), the observer's latitude, and the time of year. However, assuming you are referring to an equatorial star (one with a declination of 0 degrees) and you are at the equator (latitude 0 degrees), such that the star rises directly in the East and sets directly in the West, it would be above the horizon for approximately 12 hours out of a 24-hour day.

This is because, in this scenario, the star would cross the observer's meridian (the imaginary line running from the North celestial pole through the observer's zenith to the South celestial pole) exactly halfway between rising and setting.

H satisfies closure, identity, and inverses, it is a subgroup of G.

To prove that H={a^i * b^j : i,j∈Z} is a subgroup of G, we need to show that it satisfies the three conditions of being a subgroup: closure, identity, and inverses.

1. Closure: Take two elements h1 = a^i1 * b^j1 and h2 = a^i2 * b^j2 from H. We need to show that their product h1 * h2 is also in H.
h1 * h2 = (a^i1 * b^j1) * (a^i2 * b^j2)
       = a^(i1+i2) * b^(j1+j2)
Since i1+i2 and j1+j2 are integers, we can conclude that h1 * h2 is an element of H.

2. Identity: The identity element e of G is also in H because e = a^0 * b^0.

3. Inverses: For any element h = a^i * b^j in H, its inverse h^(-1) = a^(-i) * b^(-j) is also in H since -i and -j are integers.

(a) The values of Q1 as 2 and Q3 as 35.

(b) The dataset was arranged in ascending order, and since the total number of observations (n) is odd (13), the median was found to be the middle value, which is 5.

(c) The upper adjacent value was determined by adding 1.5 times the IQR to Q3, resulting in 87.5.

(d) The box plot of the data is illustrated below.

(a) Finding Q1 and Q3:

To determine Q1 and Q3 from the given dataset, we can start by arranging the data in ascending order: 0, 2, 3, 4, 4, 5, 6, 7, 35, 2677, 33478.

Next, we count the total number of observations (n) which is 13 in this case. We use the following formulas to calculate the position of Q1 and Q3:

Q1 = (1 * n) / 4

Q3 = (3 * n) / 4

Substituting the value of n into the formulas:

Q1 = (1 * 13) / 4 = 3.25 (approximately)

Q3 = (3 * 13) / 4 = 9.75 (approximately)

Now, we need to identify the values in the dataset that correspond to these positions. For Q1, we take the value at the position immediately below 3.25, which is 2. For Q3, we take the value at the position immediately below 9.75, which is 35.

Therefore, the values of Q1 and Q3 for the given dataset are 2 and 35, respectively.

(b) Finding the Median:

The median represents the middle value of a dataset when it is arranged in ascending or descending order. If the dataset has an odd number of observations, the median is the middle value itself. If the dataset has an even number of observations, the median is the average of the two middle values.

Arranging the given dataset in ascending order: 0, 2, 3, 4, 4, 5, 6, 7, 35, 2677, 33478.

Since the total number of observations (n) is odd (13), the median will be the middle value. In this case, the middle value is the 7th observation, which is 5.

Therefore, the median for the given dataset is 5.

(c) Finding the Adjacent Values:

Adjacent values, also known as whiskers in a boxplot, indicate the minimum and maximum values within a certain range. The range is determined using the interquartile range (IQR), which is the difference between Q3 and Q1.

For the given dataset, the IQR is calculated as follows:

IQR = Q3 - Q1 = 35 - 2 = 33

The adjacent values are determined by extending the whiskers 1.5 times the IQR below Q1 and above Q3.

Lower adjacent value = Q1 - 1.5 * IQR

Upper adjacent value = Q3 + 1.5 * IQR

Substituting the values:

Lower adjacent value = 2 - 1.5 * 33 = -47.5

Upper adjacent value = 35 + 1.5 * 33 = 87.5

Therefore, the adjacent values for the given dataset are -47.5 and 87.5.

(d) Determining the Correct Modified Boxplot:

To determine the correct modified boxplot, we need additional information or options to compare against the given dataset. Unfortunately, the options are not provided in your question. Please provide the options or any additional information related to the modified boxplot so that I can assist you further in choosing the correct one.

The equation's answer is x = 7.5. 4x - 1 2 = x + 7.

x = 1 is the answer to the problem 3x + 2 = (2x + 13) 3.

a) To solve the equation 4x - 1 ÷ 2 = x + 7, we need to isolate the variable x. Let's follow the steps:

1: Distribute the division operation to the terms inside the parentheses.

  (4x - 1) ÷ 2 = x + 7

2: Divide both sides of the equation by 2 to isolate (4x - 1) on the left side.

  (4x - 1) ÷ 2 = x + 7

  4x - 1 = 2(x + 7)

3: Distribute 2 to terms inside the parentheses.

  4x - 1 = 2x + 14

4: Subtract 2x from both sides of the equation to isolate the x term on one side.

  4x - 1 - 2x = 2x + 14 - 2x

  2x - 1 = 14

5: Add 1 to both sides of the equation to isolate the x term.

  2x - 1 + 1 = 14 + 1

  2x = 15

6: Divide both sides of the equation by 2 to solve for x.

  (2x) ÷ 2 = 15 ÷ 2

  x = 7.5

Therefore, x = 7.5 is the solution to the equation 4x - 1 ÷ 2 = x + 7. However, note that this answer is not an integer, so it may not be valid for certain contexts.

b) To solve the equation 3x + 2 = (2x + 13) ÷ 3, we can follow these steps:

1: Distribute the division operation to the terms inside the parentheses.

  3x + 2 = (2x + 13) ÷ 3

2: Multiply both sides of the equation by 3 to remove the division operation.

  3(3x + 2) = 3((2x + 13) ÷ 3)

  9x + 6 = 2x + 13

3: Subtract 2x from both sides of the equation to isolate the x term.

  9x + 6 - 2x = 2x + 13 - 2x

  7x + 6 = 13

4: Subtract 6 from both sides of the equation.

  7x + 6 - 6 = 13 - 6

  7x = 7

5: Divide both sides of the equation by 7 to solve for x.

  (7x) ÷ 7 = 7 ÷ 7

  x = 1

Hence, x = 1 is the solution to the equation 3x + 2 = (2x + 13) ÷ 3.
