To compare the measures of center of two data sets as a multiple of their measures of variation, their measures of variation must be similar. Why do you think this is true?
Answers
To compare two data sets, their variation must be similar because the variation will affect many other variables, including the mean.
What is the variation?When referring to data, the variation is about how much the data variates or the range of the data. For example, if you ask people about their age, the data can spread from 10 years old to 90 years old.
Why is variation important?This affects other variables when analyzing data such as the mean, which implies you can only compare two sets of data if the variation is similar.

if the equation is 9=3(x+2), what does x equal?
Answers
9=3x+6
3x=3
x=1
Answer:
1
Step-by-step explanation:
To solve for x, we can isolate x on one side of the equation by undoing the operation of the expression inside the parentheses. To do this, we need to subtract 2 from both sides of the equation:
9 = 3(x + 2)
9 = 3x + 6
3 = 3x
Finally, we divide both sides by 3 to obtain:
x = 1
So, the value of x is 1.

The container is filled to 87.5% of the maximum capacity.
b. Some liquid will be poured from a full 16-ounce container until it is filled to the same percent of its capacity as the large container in part a. How many ounces of liquid must be poured from the full 16-ounce container? Explain.
Note: The answers go in the blanks
When the 16-ounce container is _____% filled, it will contain _____ ounce(s). So _____ ounce(s) will need to be poured from the full 16-ounce container.
Answers
Answer:
(a) 87.5%
(b) 90%, 14.4 oz, 1.6 oz
Step-by-step explanation:
You want the fraction full a 64 oz container is if it holds 8 oz less than its capacity. You also want to know the amount that must be transferred from a 16 oz container if both containers are to be the same fraction full.
a) FractionThe amount in the 64-ounce container is ...
64 oz - 8 oz = 56 oz
The fraction of its capacity this represents is ...
(56 oz)/(64 oz) = 7/8 = 87.5%
The container is filled to 87.5% of its capacity.
b) TransferIf x is removed from a 16-ounce container and added to the 64-ounce container, their respective fill fractions are ...
(16 -x)/16 and (56 +x)/64
We want these values to be equal, so ...
(16 -x)/16 = (56 +x)/64
4(16 -x) = 56 +x . . . . . . . . . multiply by 64
64 -4x = 56 +x . . . . . . . . . eliminate parentheses
8 = 5x . . . . . . . . . . . . . . . . add 4x-56
x = 8/5 = 1.6 . . . . . . . . . . . divide by 5
When 1.6 ounces are removed from the 16-ounce container, its fill fraction will be ...
(16 -1.6)/16 = 1 - 0.1 = 0.90 = 90%
The 16-ounce container will be 90% filled, and will contain 14.4 ounces.
So, 1.6 ounces will need to be poured from the full 16 ounce container.
__
Additional comment
After receiving 1.6 ounces, the larger container will have 57.6 ounces. Its fraction full will be 57.6/64 = 90%, as required.

Answer the following linear equations: x3+y3+z3=k
2x – y = 6, x – y = 2
and ax + by = a-b, bx – ay = a+b
TYVM!! :)
Answers
Answer:
Linear Equation 1 — 3xyz
Linear Equation 2 — x = 4 and y = 2
Linear Equation 3 — x = 1 and y = (-1)
Step-by-step explanation:
(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.
The required result must be 3xyz.
(Linear Equation 2)
2x − y = 6 ....(1)
x − y = 2 ....(2)
Equation(2)−Equation(1) we get
x − y − 2x + by = 2 − 6
(−x) = (−4)
x = 4
Substitute x = 4 in (1) we get
2x − y = 6
2*4 − y = 6
8 − y = 6
(−y) = 6 − 8
y=2
(Linear Equation 3)
ax + by = a − b .......... (1)
bx − ay = a + b .......... (2)
Multiply equation (1) with a and equation (2) with b ,
a²x + aby = a² − ab ..........(3)
b²x − aby = ab + b² ......... (4)
Adding (3) and (4), we get,
(a² + b²)x = a² + b²
x = 1
Now, from (1),
ax + by = a − b
a + by = a − b
by = (−b)
y = (−1)
Hope my answer helps you ✌️

Which quadrilaterals always have diagonals that bisect opposite angels? A. Parallelograms B. Rectangles C. Rhombi D. Squares
Answers
Answer:
All of the above
Step-by-step explanation:
All of the given quadrilaterals have diagonals that bisect each other
Answer:
C. Rhombi
D. Squares
Step-by-step explanation:
You want to know which quadrilaterals always have diagonals that bisect opposite angles.
Angle bisectorIn order for a diagonal of a quadrilateral to bisect opposite angles, it must be equidistant from the sides of the angles. In effect, the sides of the angle must be the same length, and the angle-bisecting diagonal must be perpendicular to the other diagonal.
This will be the case for a kite, rhombus, or square. Among the answer choices are ...
RhombiSquares__
Additional comment
A kite has two pairs of congruent adjacent sides. The angle-bisecting diagonal bisects the angle between the congruent sides. The diagonals are not necessarily the same length, and one is bisected by the other. That is, a kite is not a parallelogram.
A rhombus is a kite with all sides congruent. The diagonals bisect each other. A rhombus is a parallelogram. Both diagonals are angle bisectors.
A square is a rhombus with equal-length diagonals.
The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.
2.17 inches
10.68 inches
21.35 inches
36.29 inches
Answers
d = 6.8 in
π (in this problem) = 3.14
Keep the formula in mind: C = 2πr
We have d, but no r. However, we know that r = 1/2d, or the radius is half the diameter.
Then again, it’s 2πr, or 2rπ, ORRRRR dπ.
So 6.8(3.14) = 21.352.
The choices only go in 2 decimal places so round.
Your answer is the 3rd choice: 21.35 in.
The required distance around the hat is approximately 21.35 inches. Option C is correct.
What is the circumference of the circle?To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.
Here,
The distance around a circle is given by the formula circumference = π × diameter.
Substituting the given values, we get:
circumference = 3.14 × 6.8
circumference = 21.352
Rounding to the nearest hundredth, we get:
circumference ≈ 21.35 inches
Therefore, the distance around the hat is approximately 21.35 inches.

Devon is making greeting cards, which she will sell by the box at an arts fair. She paid $20 for a booth at the fair, and the materials for each box of cards cost $6. She will sell the cards for $10 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How much will the sales and expenditures be? How many cards will that take?
Answers
Next, let's find out how many boxes of cards she needs to sell in order to earn enough money to cover her expenditures. She'll sell each box of cards for $10, so she'll need to sell $26 / $10 = 2.6 boxes of cards (rounded up to 3 boxes).
So, her sales will be 3 boxes * $10 per box = $30. And her expenditures and sales will both be $30

The price of fuel may increase due to demand and decrease due to overproduction. Emily is studying the change in the price of two types of fuel, A and B, over time.
The price f(x), in dollars, of fuel A after x months is represented by the function below:
f(x) = 2.96(1.04)x
Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points)
Part B: The table below shows the price g(m), in dollars, of fuel B after m months.
m (number of months) 1 2 3 4
g(m) (price in dollars) 3.04 3.22 3.41 3.61
Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.
Answers
Answer: look at the image for the answer and solution
Step-by-step explanation:
The price of fuel A is increasing by 4% per month. the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.
What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per cent refers to one hundred percent.
Part A: From the coefficient of the term (1.04)^x in the function f(x) = 2.96(1.04)^x it can be seen that the price of fuel is increasing by 4% per month. 1.04, represents the increase in price each month and exponent, x represents the number of months. The coefficient of 2.96 represents the starting price.
And hence, the price of fuel A is increasing by 4% per month
Part B: To determine the percentage change in price between each month, we need to calculate the percentage increase or decrease from the previous month's price.
For fuel A, the percentage change in price each month is given by:
100 * (1.04 - 1) = 4%
For fuel B, we can calculate the percentage change in price for each month from the table:
Percentage change:
Between months 1 and 2: 100 * (3.22 - 3.04) / 3.04 = 6.58%
Between months 2 and 3: 100 * (3.41 - 3.22) / 3.22 = 5.19%
Between months 3 and 4: 100 * (3.61 - 3.41) / 3.41 = 6.50%
Therefore, the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.
The price of fuel A is increasing by 4% per month. the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.
