Explanation:
Let's say 10 is the median, and we'll have four values above it and four below. This gives 4+1+4 = 9 total items. One such example could be {6,7,8,9,10,11,12,13,14}. This is the set of whole numbers from 6 to 14 inclusive.
Due to the symmetry of that list, the mean = median = 10
The only problem is the max is 14, when we want it to be 15. We can fix this by adding 1 to each of the upper four values {11,12,13,14} to get {12,13,14,15}.
To balance things out, subtract 1 from each of the lower four values. So we go from {6,7,8,9} to {5,6,7,8}. This balancing is to keep the mean the same at 10.
Therefore, the set {6,7,8,9,10,11,12,13,14} becomes {5,6,7,8,10,12,13,14,15} which is one possible answer.
There are infinitely many other possible answers. The data set does not have to be symmetric like this.

M is the midpoint of segment JK. The coordinate of J are (-4, 7) and the coordinates of M are (2, 5). Find the coordinates of K.
The coordinates of K are (8,3).
There is a line segment JK with M as its midpoint. This means the length of JM = length of MK.
Also the coordinates of J is (-4,7) and the coordinates for M are (2,5).
As M is the midpoint, the x-distance and y-distance between (-4,7) and (2,5) are same as that between (2,5) and K.
x- distance between (-4,7) and (2,5) = 2- (-4) = 6
So x- coordinate of K = 2+6 = 8
y-distance between (-4,7) and (2,5) = 5-7 = -2
So y-coordinate of K = 5+(-2) = 3
Hence the coordinates of K are (8,3).

On wednesday, a local hamburger shop sold a combined total of hamburgers and cheeseburgers. the number of cheeseburgers sold was three times the number of hamburgers sold. how many hamburgers were sold on wednesday?
The number of hamburgers sold on Wednesday is 141 and the number of cheeseburgers sold on Wednesday is 423
Although a part of your question is missing, you might be referring to this full question: On Wednesday, a local hamburger shop sold a combined total of 564 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Wednesday?
Total number of burgers sold on Wednesday = 564
Let the number of hamburgers sold on Wednesday be x
Let the number of cheeseburgers sold on Wednesday be y
Formulating the equation we get:
x + y = 564-----(1)
It is also given that, the number of cheeseburgers sold was three times the number of hamburgers. So,
y = 3x
Substituting y = 3x in equation (1) we get
x + 3x =564
4x = 564
x = 141
Putting x = 141 in equation (1) we get
y = 423
So, the number of hamburgers sold is 141 and the number of cheeseburgers sold is 423

By continuous function, what do you mean?A continuous function in mathematics is one that causes the value of the function to continuously vary as the input changes over time. This indicates that there aren't any discontinuities or sudden changes in value. In other words, a function is continuous if and only if its graph is devoid of any gaps or breaks. It is simple to predict where it won't be continuous for many functions. Where we have operations like division by zero or logarithms of zero, functions won't be continuous. Examples of continuous functions over the set of all real numbers are polynomial functions, exponential functions, and the sin and cosine graphs.

An uncle wills $3000 to his two nieces and one nephew. The older niece is to receive twice what the younger niece receives, and the nephew is to receive an amount equal to the sum of the nieces' amounts. How much will each person receive?
Answer:
See Explanation
Step-by-step explanation:
So, the uncle has $3000.
The Oldest Niece gets double what the Younger Niece gets half her amount. The nephew gets the total of these 2 combined.
The Youngest Niece gets $500.
500x2=1000
The Oldest Niece gets $1000.
1000+500=1500
The Nephew gets $1500.
1500+1000+500=3000

Your friend and your cousin discuss measuring with a ruler. Your friend says that you must always line up objects at the zero on a ruler. Your cousin says it does not matter. Who is correct, and why?
friend; A measurement always starts with a value of zero.
friend; A ruler does not match numbers one to one unless the measurement starts at zero.
cousin; you can choose any number for the start of the object and any number for the end.
cousin; The distance is the absolute value of the difference of the numbers lined up with the beginning and the end of the object.
The correct option is the last one:
"Cousin; The distance is the absolute value of the difference of the numbers lined up with the beginning and the end of the object."
Who is correct, your friend or your cousin?
Now, remember that a rule is equivalent to a number line.
Now, suppose that you are measuring an element with a length of 16 centimeters.
If you measure it by lining up one of the ends of the element with the zero, then the other end will be at the line number 16.
And if you line it up from a different number, let's say 3cm, then the other end of the object (which still measures 16cm) will be at 19cm.
In both cases, to find the measure of the object that you are measuring with the ruler, you need to find the difference between the two numbers on the ruler that line up with the object ends.
If you line up with the zero, you need to subtract zero, so the measure is easier:
16cm - 0cm = 16cm
If you line up with other number, like the 3 in this case, you need to perform the subtraction:
19cm - 3cm = 16cm
In both cases, we will get the same measure. So your cousin is correct, and the correct option is the last one:
Cousin; The distance is the absolute value of the difference of the numbers lined up with the beginning and the end of the object.

re 1 1/4 inches each, how many books will fit on one
shelf if each shelf measures 30 inches?
Answer:
24 books can fit on 1 shelf.
Step-by-step explanation:
Question: Juan has 28 paperback books that measure 1 and 1/4 inches each. How many books will fit on one shelf if each shelf measures 30 inches?
Step-by-step:
We know that each book is 1 and 1/4 inches each. It might be easier to convert the fraction into a decimal.
1/4 inches is 1 divided by 4 which equals to 0.25 inches
1 inch + 0.25 inches = 1.25 inches
so, 1 and 1/4 inches = 1.25 inches
To find out how many books fit on a shelf, we need to find: length of 1 bookshelf divided by length of 1 book
We know that one bookshelf is 30 inches and 1 book is 1.25 inches
so, 30/1.25 or 30 divided by 1.25 = 24
Therefore, 24 books can fit on 1 shelf.

AB ≈ 5.657
Similarly, apply sin rule in triangle ACD, we get
sin(y°) = AC /CD
sin(63°) = 4 / CD
AD = 4.489
Now distinction in lengths of AB and AD = 5.657 - 4.489

For the function h defined as h(x) = nx² + 28, n is a constant and h(3) = 1. What is the value of h(-6) ?
Answer:
Step-by-step explanation:
Step One
The first step is to find the value of n.
h(x) = n(x) + 28
h(3) = 1
That means that 1 is on the left and wherever there is an x on the right, it will have a value of 3
Step Two
Substitute values
1 = n(3) + 28
Step 3
Solve
1 = 3*n + 28 Subtract 28 from both sides
1 + - 28 = 3n Combine
-27 = 3n Divide both sides by 3
-27/3 = 3n/3
- 9 = n
Step 4
Let x = - 6 on the right side of the original equation.
