In a box-and-whisker plot, the interquartile range is a measure of the spread of the middle half of the data. Find the interquartile range for the data set: 10, 3, 7, 6, 9, 12, 13

Answers

Answer 1
In statistics, it is imperative to arrange your data entries from least to greatest. That would be the first step of our solution

3  6  7  9  10  12  13

Interquartile range is the difference of the last quartile to the first quartile. Divide your entire data set into four parts. Each division is called a quartile. Its numerical value is the average of its numbers. However, since our data set contains 7 numbers, which is odd, we write the median (middle value) twice. The quartiles are:

3  6 |  7  9 | 9  10 |  12  13

Q₁= (3+6)/2 = 4.5
Q₂ = (7+9)/2 = 8
Q₃ = (9+10)/2 = 9.5
Q₄ = (12+13)/2 = 12.5

The interquatile range is Q₄ - Q₁ = 12.5 - 4.5 = 8

The length of a rectangle is 4 inches more than its width. The area of the rectangle is equal to 4 inches less than 5 times the perimeter. Find the length and width of the rectangle. SOME HELP WITH THIS PLEASE

Answers

Let the width be w, then the length is w+4 (in).

The area of the rectangle is [tex]A=w(w+4)= w^{2}+4w [/tex].

The perimeter of the rectangle is: 

P = 2(Width + Length)=2(w+w+4)=2(2w+4)=4w+8

"The area of the rectangle is equal to 4 inches less than 5 times the perimeter." means that:

A = 5P - 4

[tex]w^{2}+4w=5(4w+8)-4[/tex]

[tex]w^{2}+4w=20w+40-4[/tex]

[tex]w^{2}-16w-36=0[/tex]

add and subtract 64 to complete the square:

[tex]w^{2}-16w+64-64-36=0[/tex]

[tex](w^{2}-16w+64)=100[/tex]

[tex](w-8)^{2}=10^{2} [/tex]

thus w= 18 or w=-2, but the width clearly cannot be negative.

w=18, the length is 18+4 = 22 (in)

Answer:

w=18 in, l=22 in

In my block of 100 flats a painter is kept employed by painting one flat each month from January to November. The flats are painted in the same order and he takes a holiday every December. If my flat was last painted in August 2010 when will it be next painted?

Answers

January to November == 11 months.

11 flats are painted every year.

100 flats / 11 flats per year = 9 years + 1 month 

the next time it will be painted is September 2019.

Answer:

The answer is September 2019.

Step-by-step explanation:

In order to determine the date of the painting flat, we have to know how the painter works.

Every year, the painter paints 11 flats, because he paints one flat each month and he doesn't work in December.

Also, if we consider that "my flat" is currently in the first position, we have to wait until the painter paints the 100 position because the painter has to paint 99 flats more.

So, "my flat was painted in August 2010", then the painter paints 3 flats more that year (September, October, November).

Now we add more painted flats every year:

3+11+11+11+11+11+11+11+11=91

At beginning of 2019, the painter has painted 91 flats. So in 9 months later, the painter will be paint the 100 position, that is in September 2019.

Finally "my flat" will be painted in September 2019.

Which expressions are equivalent to 3(x + 3y + 2x − y)?

Answers

3(x + 3y + 2x − y) = 3(3x + 2y)
= 9x + 6y
See if any of these match an answer option.
Use distributive property, and simplify like terms.

   3(x + 3y + 2x - y)
= 3(x) + 3(3y) + 3(2x) + 3(-y)
= 3x + 9y + 6x - 3y
= 9x + 6y

Therefore, 9x + 6y is equal to 3(x + 3y + 2x - y)

Also, 9x + 6y can be factored into 3(3x + 2y).
   3(3x + 2y)
= 3(3x) + 3(2y)
= 9x + 6y

So this pair is equivalent: 3(3x + 2y) and 9x + 6y

Ira purchased a new dishwasher for $361.35. The dishwasher was on sale for 17.5% off. What was the original price of the dishwasher, to the nearest dollar?

Answers

Answer: $438
To solve this equation, you cross multiply. I first subtracted 17.5 from 100 in order to get the percentage value that $361.35 was of its original price. Since 100 - 17.5 = 82.5, the washing machine is 82.5% of its original price.

I cross multiplied by writing [tex] \frac{361.35}{1} * \frac{82.5}{100} [/tex], and multiplying [tex]361.35 * 100[/tex] and [tex]82.5 * 1[/tex]. The result was [tex] \frac{36135}{82.5}[/tex]. This becomes $438. There is no rounding needed to be done.

The original price of the dishwasher with a 17.5 percentage discount is $361.

We have,

To find the original price of the dishwasher, we need to figure out what the discount amount is and subtract it from the sale price.

The discount amount is 17.5% percentage of the original price, which can be expressed as:

Discount amount = 0.175 x Original price

We can rearrange this equation to solve for the original price:

Original price = Discount amount / 0.175

The discount amount is:

Discount amount = 0.175 x $361.35 = $63.25

So the original price of the dishwasher was:

Original price = $63.25 / 0.175 = $361.43

Rounding this to the nearest dollar gives an original price of $361.

Thus,

The original price of the dishwasher with a 17.5 percentage discount is $361.

12πcrr
18πcrr
24πcrr

Answers

it's 12π, because √36=6. 6×2= 12 :)

Final answer:

The circumference of a DVD with an area of 36π cm^2 is 12π cm.

Explanation:

The question asks for the circumference of a DVD with an area of 36π cm2. The circumference C of a circle is related to its area A by the formula C = 2√(Aπ). In this case, we need to substitute the given area of the disc into the formula to calculate the circumference.

First, we'll start by plugging in the area into the formula:

C = 2 √(36π π)
C = 2 √(36)√(π)√(π)
C = 2 × 6 × π
C = 12π

Therefore, the circumference of the disc is 12π cm.

express 0.7033 as a mixed number

Answers

We can make 0.7033 an improper fraction by multiplying it by 10,000 to get:

7033/10,000

Note that this cannot be a mixed number because 10,000, the denominator, is greater than 7033, the numerator. 

You may have misspelled or typoed the question, or the question might be wrong, because 0.7033 can't be written as a mixed number.

0.7033 as a mixed number is 7033/10,000.

Understand that 0.7033 is a decimal number less than 1, meaning it will be represented as a proper fraction.
Since the decimal extends to four decimal places, the denominator will be ,
10,000 (as 10⁴ = 10,000).
= 7033/10,000.
The greatest common divisor (GCD) of 7033 and 10,000 is 1, meaning 7033/10,000 is already in its simplest form.

Therefore, the mixed number representation of 0.7033 is 7033/10,000.

The center of an ellipse is located at (0, 0). One focus is located at (12, 0), and one directrix is at x = 14 1/12.
what is the equation that represents the ellipse?????????

Answers

The standard equation for an ellipse is
[tex] \frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} =1[/tex]
where
(h,k) = coordinates of the center
a, b = semi-major and semi-minor axes

Refer to the figure shown below.
The center of the ellipse is at (0,0). 
Therefore, h=0, k=0.

One focus is at (12, 0)
Therefore
c = 12

One directrix is at  14 1/12 = 169/12.
Because the directrix is located at x = a²/c, therefore
a²/12 = 169/12
a² = 169/144
a = 13

Because c² = a² - b², obtain
b² = a² - c²
     = 169 - 144 = 25
b = 5

Answer:
The equation for the ellipse is
[tex] \frac{x^{2}}{169} + \frac{y^{2}}{25} =1[/tex]

Final answer:

The equation that represents the ellipse with the given coordinates of the center, one focus, and one directrix is x^2/144 + y^2/(25/12) = 1.

Explanation:

The equation that represents the ellipse with the center at (0, 0), one focus at (12, 0), and one directrix at x = 14 1/12 can be found using the standard form of the equation for an ellipse:

(x - h)^2/a^2 + (y - k)^2/b^2 = 1

where (h, k) is the center of the ellipse, a is the distance from the center to the vertices, and b is the distance from the center to the co-vertices.

Since the center is at (0, 0), the equation becomes:

x^2/a^2 + y^2/b^2 = 1

The distance from the center to one focus is 12, so the value of a is 12. To find the value of b, we need to use the distance from the focus to the directrix. Since the directrix is x = 14 1/12, the distance from the focus to the directrix is |14 1/12 - 12|. Simplifying, we get |14 1/12 - 12| = 2 1/12. Therefore, the value of b is 2 1/12.

Substituting these values into the equation, we get:

x^2/144 + y^2/(25/12) = 1
