What does it mean for a number to be irrational?
And irrational number is a number than cannot be written as a simple fraction.
Two good examples of irrational numbers are PI and the square root of 2. These numbers have never-ending decimals, and their decimals never repeat.
Answer:
An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Determine whether the following statement is true or false. Explain. When obtaining a stratified sample, the number of individuals included within each stratum must be equal. Choose the correct answer below. A. False. A stratified sample is constructed by successively selecting a stratum at random and then selecting a random individual from within that stratum. With this process, it is unlikely that all strata will be sampled from the same number of times. B. False. Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population. C. True. Sampling the same number of people from each stratum will result in a sample that is representative of the population at a lower cost than a simple random sample. D. False. When taking a stratified sample, a simple random sample is drawn from one stratum at random. All other strata will not be included in the sample.
Answer:
B. False. Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.
Step-by-step explanation:
In a stratified sample, each stratum should be proportional to that category of the population. This means that each stratum would potentially have a different number of elements in it.
The statement is false. Stratified sampling does not require the number of individuals to be equal within each stratum.
Explanation:The statement 'When obtaining a stratified sample, the number of individuals included within each stratum must be equal' is False. When using stratified sampling, the number of individuals included within each stratum does not have to be equal. In stratified sampling, the population is divided into different groups or strata based on certain characteristics, and then individuals are randomly selected from each stratum. The number of individuals selected from each stratum is often proportional to the size of the stratum in the population, which makes the sample more representative.

Enlarge the shapes using the scale factor 1:2
Answer:
the picture is correct
Step-by-step explanation:
Each square on the original shape becomes 2 squares on the enlarged shape, just as you have drawn.
Enlarging shapes using a scale factor of 1:2 involves multiplying each side length by 2.
To enlarge a shape using a scale factor of 1:2, each side length of the shape needs to be multiplied by 2. For example, if a square has sides of length 4 cm, when enlarged with a scale factor of 1:2, each side will become 8 cm. This is because multiplying 4 by 2 gives us 8.
Similarly, if a triangle has side lengths of 6 cm, 8 cm, and 10 cm, when enlarged with a scale factor of 1:2, the new side lengths will be 12 cm, 16 cm, and 20 cm. Each side length is multiplied by 2
Remember, the scale factor tells you how many times larger the new shape will be compared to the original shape. In this case, every length of the shape is being doubled.

Step-by-step explanation:
Given in the question an expression
ln[tex]\frac{1}{\sqrt{e^3} }[/tex]
First apply logarithm divide rule
[tex]ln\frac{1}{\sqrt{e^3} }[/tex] = ln1 - ln√e³
ln(1) = 0
so
ln1 - ln√e³ = 0 - ln√e³
-ln√e³ = -ln(e³)^1/2
Apply logarithm power rule
- ln(e³)^1/2 = -lne[tex]^\frac{3}{2}[/tex]

Determine which polynomial is a difference of two squares. a. X2 + 14 b. X2 ? 14 c. X2 + 49 d. X2 ? 49
Answer:
d. X^2 - 49
Step-by-step explanation:
I will assume that the question marks are minus signs.
Let's remember what does "difference of two squares" means:
The difference of two squares is a number multiplied by itself subtracted from another number multiplied by itself (the number multiplied by itself is called squared number).
In our options, the first number is always a squared number because it's X^2 = X * X.
We just have to analyze the second number.
First, let's notice that a. and c. can't be correct because we have a sum instead of a subtract.
We have left 14 and 49 to analyze:
14 = 7*2 (it's not a squared number)
49 = 7*7 (it's a squared number)
The answer is X*X - 7*7 = X^2 - 49
Find y of this shape.
as shown in figure LN = KN
triangle KLN is right angle triangle so using Pythagoras theorem
KL^2 = LN^2 + KN^2
KL^2 = LN^2 + LN^2 = 2LN^2
KL = √(2LN^2)
y = LN√2
now lets find value of LN
now LMN is also right angle triangle so using trigonometry
MN/LN = sin 30
putting value of MN=5 and sin 30 which is 1/2
5/LN = 1/2
LN = 5×2= 10
putting it back in our first equation
y = LN√2
y = 10√2
Can a hermaphrodite have a baby with them self..............
no a hermaphrodite can not have a baby with themselves that is not possible
Hermaphroditism varies across different species, So, some organisms may have evolved the ability to self-fertilize under certain conditions, while others may not have that capability at all.
A "hermaphrodite" is an organism that has both male and female reproductive organs. While hermaphroditic organisms have the potential to produce both sperm and eggs, self-fertilization, or the ability to fertilize their own eggs with their own sperm, is not a common occurrence in nature.
In most cases, hermaphroditic organisms still require a mate to reproduce. They can engage in a process called reciprocal fertilization, where two hermaphroditic individuals exchange gametes (sperm and eggs) to fertilize each other's eggs. This allows for genetic diversity and avoids the limitations associated with self-fertilization.
However, it's important to note that hermaphroditism varies across different species, and the reproductive mechanisms can be complex. Some hermaphroditic organisms may have evolved the ability to self-fertilize under certain conditions, while others may not have that capability at all.
In summary, while hermaphrodites have both male and female reproductive organs, self-fertilization is not a universal characteristic among them.

EXPLANATION
Two expressions for the angles in terms of x are given,
The first one is (10x-20)°
The second one is (6x+8)°
The two angles are angles on a straight line.
The sum of angles on a straight line is 180°.
This implies that,
[tex](10x - 20) \degree + (6x + 8) \degree = 180 \degree[/tex]
Group similar terms,
[tex]10x + 6x= 180 + 20 - 8[/tex]
Combine like terms:
[tex]16x=192[/tex]
[tex]x = \frac{192}{16} = 12[/tex]
Therefore the value of x is 12
The value of x is 12°
AngleAngle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Given
The angles are (10x - 20)° and (6x + 8)°.
To findThe value of x.
How to find the value of x?The angles are (10x - 20)° and (6x + 8)°.
We know that the sum of the angles of the line is 180°. then
(10x - 20)° + (6x + 8)° = 180°
Then simplify the equation, we have
10x - 20 + 6x + 8 = 180
16x - 12 = 180
16x = 180 + 12
16x = 192
x = 12°

point A is locatee at (2,8) and point B is located at (8,5). what point partitions the directed line segment AB into a 1:3 ratio
Answer:
The point is (3.5 , 7.25)
Step-by-step explanation:
∵ A = (2 , 8) and B = (8 , 5)
∵ Let point P divides AB into a ratio 1:3
∵ [tex]x=\frac{m_{2}x_{1}+m_{1}x_{2}}{m_{1}+m_{2}}[/tex]
∵ [tex]y=\frac{m_{2}y_{1}+m_{1}y_{2}}{m_{1}+m_{2}}[/tex]
∴ x-coordinate of P = (2)(3) + (8)(1)/3 + 1 = (6 + 8)/4 = 3.5
∴ y-coordinate of P = (8)(3) + (5)(1)/1 + 3 = (24 + 5)/4 = 7.25
∴ P = (3.5 , 7.25)
The point that partitions the directed line segment AB into a 1:3 ratio is P(3.5, 7.25), calculated using the section formula.
To find the point that partitions the directed line segment AB into a 1:3 ratio, we use the section formula. The section formula for a point P(x, y) that divides the line segment connecting A(2, 8) to B(8, 5) in the ratio m:n is given by:
x = ([tex]m \times x2 + n \times x1[/tex]) / (m + n)
y = ([tex]m \times y2 + n \times y1[/tex]) / (m + n)
Given the ratio 1:3, the coordinates for point P can be calculated as follows:
x = ([tex]1 \times 8 + 3 \times 2[/tex]) / (1 + 3) = (8 + 6) / 4 = 14 / 4 = 3.5
y = ([tex]1 \times 5 + 3 \times 8[/tex]) / (1 + 3) = (5 + 24) / 4 = 29 / 4 = 7.25
Therefore, the point that divides the line segment AB in a 1:3 ratio is P(3.5, 7.25).

B. g(x) = 7(x - 6)
C. g(x) = 7(x + 6)
D. g(x) = 7x - 6
the correct answer choice is B.
The equation of the graph for the function f(x) = 7x after being shifted 6 units to the right is g(x) = 7(x - 6), which is option B.
Explanation:When a graph of the form f(x) = mx is shifted horizontally, this is represented in the equation by manipulating the x variable within the function. A shift to the right by 6 units results in the input value being decreased by 6 before it is multiplied by the slope (in this case, 7). Therefore, the new equation reflecting a horizontal shift to the right is g(x) = 7(x - 6), which corresponds to option B.
