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?
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.

Two trains, Train A and Train B, weigh a total of 346 tons. Train A is heavier than Train B. The difference of their weights is 238 tons. What is the weight of each train?
Answer:
A=292, B=64
Step-by-step explanation:
A+B=346 equ 1
A>B
A-B=238 equ 2
A=238+B
input into equ 1
238+B+B=346
238+2B=346
collect like terms
2B=346-238
2B=108
divide both sides by 2
B=54
A=238+B
A=238+54
A=292
write as a product bx^2+2b^2-b^3-2x^2

Answer:
5)= U(-3,0), M(-1,4), L(-2,0)
6)= R(-4,2), D(-4,5), L(0,2)
Step-by-step explanation:
The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the translated figure be represented as A
Now , the coordinates of the figure are
a)
The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
b)
The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
Hence , the translation is solved

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 9(1.04)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?
Answer:
Step-by-step explanation:
Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.
Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.
Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.
Find the area of a triangle with a base length of 4 units and a height of 5 units. (1 point)
a
8 square units
b
9 square units
c
10 square units
d
20 square units
Answer: C. 10
Step-by-step explanation:
The area formula for a triangle is 1/2 × b × h where b is the base and h is the height. If we plug in the length and height for the formula, we will get 1/2 x (4) x (5).
=1/2 (20)

Which quadrilaterals always have diagonals that bisect opposite angels? A. Parallelograms B. Rectangles C. Rhombi D. Squares
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 average grain of salt is 0. 0003 meters wide. Rhinovirus, which causes the common cold, is 0. 00000003 meters wide. How many times wider is a grain of salt than Rhinovirus? Choose the correct answer. A. 1 × 102 times B. 1 × 103 times C. 1 × 104 times D. 1 × 105 times
Number of times a grain of salt is wider than Rhinovirus
= width of average grain of salt / width of rhinovirus
=0.0003 / 0.00000003
=1 × 10^4
Hence, the number of times a grain of salt is wider than Rhinovirus is 10,000 times.

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red. Determine the theoretical probability of the spinner not landing on yellow, P(not yellow).
Answer: 0.75 or [tex]\frac{3}{4}[/tex]
Step-by-step explanation: Well there are 2 section colored purple, 2 sections yellow, 3 sections are blue, and 1 section is red.
First lets find the number of favorable outcomes, which would be outcomes with out yellow. 6 out of 8 sections do not have yellow therefore the amount of favorable outcomes is 6.
Now for the total amount of outcomes which is 8.
If we input those numbers in this formula [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] so [tex]\frac{6}{8}[/tex] we get 0.75 or [tex]\frac{3}{4}[/tex].
