We can conclude that both data set have the same interquartile range but different median because the median of Friday is greater than the median of Saturday.

A boxplot is a type of chart that is used for the graphical representation of the five-number summary of any data set based on locality, skewness, and spread. Also, the five-number summary of a data include the following:

From the given boxplot we can deduce the following points:

On Friday: Q₁ = 200, Q₂ = 215, Q₃ = 220 and IQR = 20.

On Saturday: Q₁ = 190, Q₂ = 205, Q₃ = 210 and IQR = 20.

Therefore, we can deduce that both data set have the same interquartile range (IQR) but different median because the median of Friday is greater than the median of Saturday.

Answer:

Option C, x - 2y = -16

Step-by-step explanation:

Step 1:  Find the slope

[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]

[tex]m = (11 - 10) / (6 - 4)[/tex]

[tex]m = 1 / 2[/tex]

Step 2:  Plug in into point-slope form

[tex](y - y_1) = m(x - x_1)[/tex]

[tex](y - 10) = 1/2(x - 4)[/tex]

[tex]y - 10 = 1/2x - 2[/tex]

Step 3:  Solve for x

[tex]y - 10 + 2 = 1/2x - 2 + 2[/tex]

[tex](y - 8) * 2/1 = 1/2x * 2/1[/tex]

[tex]2y - 16 = x[/tex]

Step 3:  Put the variables on one side

[tex]2y - 16 - 2y = x - 2y[/tex]

[tex]-16 = x - 2y[/tex]

[tex]x - 2y = -16[/tex]

Answer: Option C, x - 2y = -16

112 tiles

Step-by-step explanation:

Area = 28ft sq

Tiles are 1/4 each sqft

We are working cube square inside cube ft square = 1 sq /4 (for multiplier).

Answer:

$577.27

Step-by-step explanation:

When offered 15% discount, buyer will then pay 100-15=85% of the original price hence the price offered by seller will be

0.85*$630=$535.5

Now this price is subjected to a tax of 7.8%, equivalent to 0.078 hence the buyer pays 1.078 of $535.5

1.078*$535.5=$577.269

Rounded off, this is equivalent to $577.27

The surface area of the cylinder, with a radius of 39 inches and a height of 33 inches, is calculated using the formula for the surface area of a cylinder. It amounts to a total of 7386pi square inches, separating the calculation into the lateral surface area and the area of the bases for clarity.

The question is about finding the surface area of a cylinder where the radius of the base is 39 inches and its height is 33 inches, all in terms of pi. To find the surface area of a cylinder, we use the formula: 2(pi)(r)(height) + 2(pi)(r)^2. Substituting the given values, we have 2(pi)(39)(33) for the surface area of the sides, and 2(pi)(39)^2 for the two circular ends.

Therefore, the total surface area in terms of pi is: 2(pi)(39)(33) + 2(pi)(39)^2. This simplifies to: 2562pi + 4824pi, resulting in a total surface area of 7386pi square inches.

This approach easily demonstrates the process of calculating the surface area of a cylinder by focusing on its geometrical components: the lateral surface area and the area of the two circular bases.

Mode is the most repeated value here we can see the most repeated value is 6, So it's mode is 6.

Answer:  The mode would be 6.  The mode is the number that occurs the most in a given data set.  When solving for mode, I arrange the numbers in ascending order so the most frequent number is easier to spot.

Step-by-step explanation:

9, 10, 6, 5, 6

5, 6, 6, 9, 10

In the second order of the numerals, the mode is much more obvious than in the first.  I also recommend highlighting or bolding the mode so transferring your work is easier.  There can be multiple modes if there are a few numbers in the set that occur the same amount.  There can also be no mode if all the numbers occur the same amount

$6+$1.10=$22.50

Add 1.10 to 6 ,15 times And you will get 22.50

Answer =15 miles

The question is asking how long was Sarah's taxi ride based on the taxi fare. This can be solved using algebra to set up an equation and solve for the total miles. The solution indicates that Sarah traveled a total of 18 miles.

This question involves a concept in algebra known as linear equations, which are used to express variable relationships. Similar to the Svetlana's tutoring fee problem, this taxi fare problem can be solved by writing an equation based on the given information.

The equation would look like this: $6.00 + $1.10(miles - 3) = $22.50 where miles represent the total miles traveled by Sarah. Subtract $6.00 from both sides: $1.10(miles - 3) = $16.50. Divide both sides by $1.10 you get: miles - 3 = 15. Now, if we add 3 to both sides of the equation, we get: miles = 15 + 3 = 18.

So, Sarah traveled a total of 18 miles for her taxi ride.

From the given options, the only logarithmic function is the first one:

y = log₃(x).

We define the general logarithmic function, the natural logarithm, as the inverse of the exponential function, such that:

Ln(e^x) = x

And we can also have logarithms in other bases written as:

logₐ(x) = Ln(x)/Ln(a)

Answer:

D. 6 < x < 22

Step-by-step explanation:

For a triangle, the third side must be less than the sum of the other two sides and it must greater than the difference between the other two sides.

The possible length of the third side of the triangular pen, given the Triangle Inequality Theorem and two given side measures, is best described by the inequality D. 6 < x < 22.

To find the possible length of the third side of a triangle, we use the Triangle Inequality Theorem. The theorem states that the length of any side of a triangle is less than the sum of the lengths of the other two sides and greater than the absolute difference of the lengths of the other two sides. Here, we have the lengths of two sides as 14 ft and 8 ft.

So the sum of these two sides is 14 + 8 = 22 ft. The difference is |14 - 8| = 6 ft. Therefore, the length of the third side 'x' can range between the sum and the difference of the other two sides. Hence, the correct answer is D. 6 < x < 22.
