The summary of the given data is Min = 44, Q1 = 48, Median = 50.5, Q3 = 53, Max = 56 . So option C is correct.
What is the median?The middle number of data in a collection is known as the median. Three alternative metrics are employed in mathematics to determine the average value for a given group of integers. They are the median, mode, and mean. The measures of central tendency are this trio of measurements.
Median = [(n/2)th term + {(n/2)+1}th term]/2 (for even)
Median = {(n+1)/2}th term (for odd)
Based on the given information,
we can see that the box plot shows the values of 44, 48, 50.5, 53, and 56.
These values represent the minimum, lower quartile (Q1), median, upper quartile (Q3), and maximum, respectively.
Therefore, the five-number summary for this data is:
Min = 44,
Q1 = 48,
Median = 50.5,
Q3 = 53,
Max = 56
So the answer is: Min = 44, Q1 = 48, Median = 50.5, Q3 = 53, Max = 56

Answer: TASK 1: The answer to how much more of the atmosphere is nitrogen than all other gases combined can be found by measuring the atmospheric composition. Nitrogen makes up the largest fraction of the Earth's atmosphere, at around 78%. Oxygen makes up around 21%, while all other gases make up the remaining 1%. So, nitrogen makes up around 77% more of the atmosphere than all other gases combined.

Hope it helps you~Students are reading a book that has 280 pages. Nora already read 30% of the book. She is choosing between two options to finish reading the book.
Option 1: read 25% of the remaining pages each night
Option 2: read 28 pages each night
Which option should Nora use to finish the book in the least amount of time?
Explain your reasoning.
Answer:
Step-by-step explanation:
To determine which option is faster, we need to determine the total number of nights required for each option.
First, let's find the number of pages Nora still needs to read by subtracting the number of pages she's already read from the total number of pages: 280 pages * 30% = 84 pages
So, Nora still needs to read 280 pages - 84 pages = 196 pages.
For Option 1, Nora would read 25% of the remaining pages each night, so the number of pages she reads each night would be: 196 pages * 25% = 49 pages
The total number of nights required would be 196 pages / 49 pages/night = 4 nights.
For Option 2, Nora would read 28 pages each night, so the total number of nights required would be 196 pages / 28 pages/night = 7 nights.
Since 4 nights is less than 7 nights, Nora should choose Option 1 to finish reading the book in the least amount of time.
The base of a triangle is 2inches more than 2 times the height. If the area of the triangle is 12 square inches, find the base and height.
Answer:
Base: 8. Height: 3.
Step-by-step explanation:
Let the height be x. Then the base would be 2x+2. The formula for the area of a triangle is 1/2*base*height. We know the area, and we know the base and height in terms of x. Now you just solve for x. 1/2*x*(2x+2) = 12. x(2x+2) = 24. You could plug in factors of 24, but I used the quadratic formula to solve this equation. 2x^2 +2x -24 = 0. Plugging in these values into the quadratic formula, we get that x = 3. This means that the height is 3. Since the base is 2x+2 and x is 3, then the base is 8.
-2√x+5 +1
End behavior
Answer: The end behavior of a function is the behavior of the function as x approaches positive infinity or negative infinity.
For the function f(x) = -2√x + 5 + 1, as x approaches positive infinity, the square root of x approaches positive infinity as well. So, the function approaches negative infinity as x approaches positive infinity:
lim x → ∞ f(x) = lim x → ∞ -2√x + 5 + 1 = -∞
As x approaches negative infinity, the square root of x approaches 0, so the function approaches:
lim x → -∞ f(x) = lim x → -∞ -2√x + 5 + 1 = 7
Therefore, the end behavior of the function is that it approaches negative infinity as x approaches positive infinity, and it approaches 7 as x approaches negative infinity.

The combined volume of a 4-foot cube and a 6-foot cube is not equal to the volume of a 10-foot cube.
What is the volume of the cube?The volume of a cube is calculated by cubing the length of its side.
here,
Let's denote the length of the sides of the 4-foot and 6-foot cubes as "a" and "b", respectively. Then the length of the side of the 10-foot cube is "c", and we know that:
a³ + b³ = c³
We want to confirm if the combined volume of a 4-foot cube and a 6-foot cube is equal to the volume of a 10-foot cube. We can calculate the volumes of the cubes as follows:
Volume of 4-foot cube: a³ = 4³ = 64 cubic feet
Volume of 6-foot cube: b³ = 6³ = 216 cubic feet
Volume of 10-foot cube: c³ = 10³ = 1000 cubic feet
The sum of the volumes of the 4-foot and 6-foot cubes is:
64 + 216 = 280
Therefore, the combined volume of a 4-foot cube and a 6-foot cube is not equal to the volume of a 10-foot cube.

For part c:
The statistics on children whose parents do not have secure employment provide important insights into the state of the economy. In this case, the mean and median of the number of children in each state seem to be around 450,000. The mode cannot be determined since there are no repeated values in the "Number" column. The maximum number of children is 678,000 in Ohio, while the minimum number is 141,000 in Iowa.
Comparing the states, Indiana has a slightly higher mean and median percent of children whose parents do not have secure employment at 27%, compared to the other surrounding states which range from 20% to 31%. However, there is no clear state with the best or worst data as the range of the percent values is not too wide.
In terms of comparison, the number of children may provide a more comprehensive understanding of the extent of the problem, as it gives a clearer picture of the actual number of children affected. However, the percentage provides a more relative comparison between the states, allowing for easier comparison and a clearer understanding of the proportion of children affected in each state.

What is r in the following equation? 5(-4) - r +1 = -37 PLEASE HELPP ILL GIVE EXTRA CREDIT
Answer:
Step-by-step explanation:
5 times -4 is -20, so the equation becomes -20 - r + 1 = -37
-20 plus 1 equals -19, so the equation is now -19 - r = -37
Then you add 19 to both sides to isolate r
-r = -18
To get a positive r, divide or multiply both sides by -1, and you get r = 18
[tex]5(-4)-r+1=-37[/tex]
Simplify:
[tex]-20-r+1=-37[/tex]
Combine Like Terms:
[tex](-r)+(-20+1)=-37[/tex]
[tex]-r-19=-37[/tex]
Add 19 to both sides:

4. The first term in the sequence is 5 and the fifth term is 17. What is the common difference?
(1) 2.4
(2) 12
(3) 3
(4) 4
Answer:
(3) 3
Step-by-step explanation:
Arithmetic Sequence:An arithmetic sequence is a sequence of numbers in which each of them can be defined by adding a common difference to a term to find the next term.
So for example, let the first term, or number be expressed as: [tex]a_1[/tex] and the common difference be expressed as: [tex]d[/tex] That means the second term, or number can be defined as: [tex]a_2=a_1+d[/tex]. If we now add the common difference to the second term, we would get the third term, and so on.
An arithmetic sequence can be compared to that of a linear equation, except it's a sequence of numbers... and also it's restricted to integers greater than zero (starts at first term, second term.... and so on)
So the common difference can be compared to the slope, and we can actually just use the slope formula! The "x" value being the term number, and the "y" value being the term. So the first term in the sequence is 5 can be expressed as: (1, 5) and the fifth term is 17 can be expressed as (5, 17). Now using the slope formula we would get: [tex]d=\frac{17-5}{5-1}=\frac{12}{4}=3[/tex]
Another way to think of it is the first term is 5, and if we add "d" or the common difference to it, we get the second term, if we add another "d" we get the third term, if we another "d" we get the fourth term and if add yet another "d" we get the fifth term. We add a total of four "d's" which can be expressed as: [tex]5+4d[/tex] and this equals the fifth term, but we also know this to be equal to 17, so we can set them equal to each other: [tex]5+4d=17[/tex] now just subtract 5 and divide by 4 to get: [tex]d=3[/tex]
