What is the interquartile range of this data?
6
7
8
9
Step 1: Find Q2
Note - Q2 is basically the median of the set
We see that the two numbers in the middle are 28 and 32.
To get the median, find the average of 28 and 32.
28 + 32 = 60, 60/2 = 30
Q2 = 30
Step 2: Find Q1
The median splits the set. So anything before 30, is what we should focus on.
In this case, it's: 12, 16, 20, 24, and 28
Find the median of those five numbers. We get: 20
Q1 = 20
Step 3: Find Q3
Similar to before, focus on the numbers after 30.
In this case, it's: 32, 36, 40, 44, 48
Find the median of those five numbers. We get: 40
Q3 = 40
Step 4: Find the IQR
The IQR (Interquartile Range), as shown in its name, is found by subtracting Q3 and Q1.
Q3 - Q1 = 40 - 20 =20
IQR = 20
Answer:
20

Answer:
15
Step-by-step explanation:
This is quite simple, if you know what your doing, but first yyou got to remember that those inside lines measure to a 90 degree angle. So take your expression: 6x = 90 or 4x + 30, and fit in the correct number (Which is 15!) should get you 90. I hope this helps :D
Answer:
x=15
Step-by-step explanation:
This equation is actually very easy because the angles are 90° meaning that the sum should equal 90. You should know that when 2 numbers eg. ab are placed together it basically means a x b so we have to figure out x in the equation 6 x x. We simply do this by dividing 90 (cuz that's our angle) by 6 which gives us the answer 15. (you can double check this by doing 15 x 6 which will still give you 90). This means that x= 15!
Now the bottom equation will become (4 x 15) + 30. We break it up by doing 4x15 which equals 60 and then 60 plus 30 equals 90, meaning that we are correct!

Step-by-step explanation:
The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the rectangle.
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!
In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

What does _ mean in a math equation I'll add a picture of the problem
Answer:
the _ is supposed to mean the answer ,which you the person who will calculate the answer and write it on the _
Step-by-step explanation:
(4) (14-9)+2=_
14-9=5
so,
(5)+2=_
well, 5+2 is 7
so on the _ you will write 7
Answer: The answer for 4 is 7 and for 6 it's 14 and the slash means to divide
Step-by-step explanation: (14-9)+2 first solve the parentheses then the outside so 14-9 would be 5 and you would 5+2 which then equals 7. then for the second we do the same solve within the parentheses 8+6 equals 14/ 2-1 then we subtract and have 14/1 and anything divided by 1 stays the same which equals 14.

The ratio of keepers to animals in the city zoo is 2 : 7. 12 keepers and 42 animals. If 21 more animals are added, how many total keepers are needed to maintain the ratio of keepers to animals?
A. 16
B. 17
C. 18
D. 19
E. 20
Answer:
C: 18
Step-by-step explanation:
All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.

Find all possible values of a such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1.
Answer:
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0\)
Step-by-step explanation:
Given quadratic equation:
\(ax^2 + (2a + 2)x + a + 3 = 0\)
To find the possible values of "a" such that the given equation has two roots and the distance between them on the number line is greater than 1, use the quadratic formula.
\(\boxed{\begin{minipage}{4 cm}\underline{Quadratic Formula}\\\\$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$\\\\when $ax^2+bx+c=0$ \\\end{minipage}}\)
Comparing the coefficients:
\(a = a\)\(b = (2a + 2)\)\(c = (a + 3)\)Substitute the coefficients into the quadratic formula:
\(x=\dfrac{-(2a+2) \pm \sqrt{(2a+2)^2-4a(a + 3)}}{2a}\)
Simplify the discriminant (the part under the square root sign):
\(x=\dfrac{-(2a+2) \pm \sqrt{-4a+4}}{2a}\)
Factor out 4 from the discriminant:
\(x=\dfrac{-(2a+2) \pm \sqrt{4(-a+1)}}{2a}\)
\(\textsf{Apply the radical rule:} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}\)
\(x=\dfrac{-(2a+2) \pm \sqrt{4}\sqrt{-a+1}}{2a}\)
Therefore:
\(x=\dfrac{-(2a+2) \pm 2\sqrt{-a+1}}{2a}\)
Factor out the common term 2:
\(x=\dfrac{-(a+1)\pm \sqrt{-a+1}}{a}\)
Therefore, the two solutions are:
\(x=\dfrac{-a-1+\sqrt{-a+1}}{a},\;\;x=-\dfrac{a+1+\sqrt{-a+1}}{a}\)
As both solutions have "a" as their denominator, a ≠ 0.
Note: When substituting a = 0 into the original equation, we are left with a linear equation, which only has one root. Therefore, this confirms that a ≠ 0.
Now we have found expressions for the two roots, we can set the distance between them to greater than 1:
\(\dfrac{-a-1+\sqrt{-a+1}}{a}-\left(-\dfrac{a+1+\sqrt{-a+1}}{a}\right) > \:1\)
\(\dfrac{-a-1+\sqrt{-a+1}}{a}+\dfrac{a+1+\sqrt{-a+1}}{a} > \:1\)
Simplify:
\(\begin{aligned}\dfrac{-a-1+\sqrt{-a+1}+a+1+\sqrt{-a+1}}{a}& > 1\\\\\dfrac{2\sqrt{-a+1}}{a}& > 1\\\\2\sqrt{-a+1}& > a\\\\(2\sqrt{-a+1})^2& > a^2\\\\4(-a+1)& > a^2\\\\-4a+4& > a^2\\\\a^2+4a-4& < 0\\\\(a+2)^2-8& < 0\\\\(a+2)^2& < 8\end{aligned}\)
\(\textsf{For\;\;$u^n < a$,\;\;if\;$n$\;is\;even\;then\;\;$-\sqrt[n]{a} < u < \sqrt[n]{a}|$:}\)
\(-\sqrt{8} < a+2 < \sqrt{8}\)
Therefore:
\(-\sqrt{8} -2 < a < \sqrt{8}-2\)
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2\)
So the possible values of "a" such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1 are:
\(\large{\boxed{-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0}\)
A runner completed a 26.2-mile marathon in 210 minutes.
- Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth.
- Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth.
- Another runner says, "I averaged 10-minute miles in the marathon." Is this runner talking about the unit rate described in part (a) or in part (b)?
- Explain your reasoning.
Answer:
0.123 miles per min
8 mins per mile
The runner is talking about part (b)
Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b
Step-by-step explanation:
Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute
And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.
