Answer:

Step-by-step explanation:
all value between 1 to 5 except 5 is shown on graph
The domain of a function is the set of input values the function can take.
The domain of the graph is [tex]\{x |1 \le x < 5\}[/tex]
From the graph of the piece-wise function, we have the following highlights
The x-values begin at x = 1 with a closed circleThe x-values end at x = 5 with an open circleThe above highlights can be represented using the following inequality
1 <= x < 5
Rewrite properly as:
[tex]\{x |1 \le x < 5\}[/tex]
Hence, the domain of the graph is [tex]\{x |1 \le x < 5\}[/tex]

about the homework policy. Which of the following uses cluster sampling?
O Roll a fair number cube. Use the number rolled to pick a row of students. Survey every student in that row.
List the students according to their grade in the class. Survey one A student, one B student, etc.
For each row, flip a coin. If it is heads, survey all the boys in that row. If it is tails, survey all the girls in that row.
O Select a student by rolling a fair number cube twice. The first roll gives the row number, and the second roll gives
the seat number. Then repeat.

Step-by-step explanation:
Edge 2021
The teacher is using a number cube to select a row of students and then surveys every student in that row, which fits the definition of cluster sampling.
What is the sampling distribution?In statistics, sampling distribution refers to the study of numerous random samples drawn from a particular population depending on a specified property. The gained data paint a clear notion of the changes in the likelihood of the outcomes determined.
Cluster sampling is a type of sampling technique in which a group or cluster of units is selected from the population and then all units within the selected clusters are included in the sample.
In this case, the teacher is using a number cube to select a row of students and then surveying every student in that row, which fits the definition of cluster sampling.
Thus, the correct answer would be an option (A).

This question is so hard
Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.

Answer:
180° (in place of blank)
Step-by-step explanation:
GIVEN :-
∠D = 127°∠A = 75°PROCEDURE :-
∠C & ∠D are linear pair. (∵ They lie on same line)
⇒ ∠C + ∠D = 180°
⇒ ∠C = 180° - 127°
In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,
∠A + ∠B + ∠C = 180°
⇒ 75° + ∠B + (180° - 127°) = 180°
⇒ ∠B = 180° - 75° - (180° - 127°)

Given:
Coordinates of point N = (-2,-6)
Point N is reflected over the y-axis to create point N ′.
Point N' is then reflected over the x-axis to create point N''.
To find:
The ordered pair that describes the location of N''.
Solution:
The coordinates of point N are (-2,-6). Point N is reflected over the y-axis to create point N ′.
[tex](x,y)\to (-x,y)[/tex]
[tex]N(-2,-6)\to N'(2,-6)[/tex]
Point N' is then reflected over the x-axis to create point N''.
[tex](x,y)\to (x,-y)[/tex]
[tex]N'(2,-6)\to N''(2,6)[/tex]
Therefore, the ordered pair for point N'' is (2,6).

Answer A states, "save at least $72." If the inequality used a greater than or equal to sign this could work, yet it uses a > symbol. I would go with B & C, if you haven't chosen already.

AA’ = BB’
AA = BB
AB = BB
A’A’ = B’B’
Answers
Answer:
AA’ = BB’
Step-by-step explanation:
Suppose that we have a point (x, y), and we apply a transformation that translates this point in a given direction, let's suppose that we translate n units in the horizontal axis, and m units in the vertical axis.
Then the new coordinates of the point will be (x+ n, x + m)
Notice that for any point (x, y) the distance between the original point and the translated point (x + n, x + m) is always the same.
D = √( (x - (x + n))^2 + (y - (y + m))^2)
D = √ ( n^2 + m^2)
Here you can see that there is no dependence with the original coordinates of the point.
So if we have a line and we translate it with a translation like the one defined above, the distance between all the points in the original line and the corresponding point in the translated line is always the same.
Then if we have the point A, and after the translation, it becomes A', the length of the segment AA' is equal as the distance between A and A'.
And exactly the same happens for B and B'.
Then if the distance between A and A', is the same as the distance between B and B', then:
AA' = BB'
Answer:
AA’ = BB’
Step-by-step explanation:
A transformation produces a mapping of points whose distances are congruent.
Matrices of different dimensions can be added together.

The image is an example of which type(s) of symmetry?
A. Reflectional
B. Neither rotational ner reflectional
C. Both rotational and reflectional
O
D. Rotational
Answers
The given image of the square is an example of (C) both rotational and reflection symmetry.
What are rotational and reflection symmetry?The rotational symmetry of a shape explains why an object's shape remains unchanged when it is rotated about its own axis. If a geometric shape is rotated 180 degrees or at certain angles, either clockwise or counterclockwise, many of them seem to be symmetrical. Square, circles, hexagons, and other shapes are a few examples.A sort of symmetry that pertains to reflections is called reflection symmetry. Line symmetry and mirror symmetry are other names for reflection symmetry. If a figure has at least one line dividing it into two halves, one half is said to be the mirror image of the other half.So, the given diagram of the square satisfies the situation of both rotational and reflection symmetry.
Therefore, the given image of the square is an example of (C) both rotational and reflection symmetry.

A rectangle has side lengths x + 2 and x - 1. What is the perimeter of the rectangle
when x = 5?
Answers
Answer:
22 units
Step-by-step explanation:
The perimeter is all the sides of any polygon added up.
A rectangle has 4 sides, but we only need two sides to solve this because a rectangle has symmetry
There are two ways
Method 1:
x+2 + x-1 + x+2 + x-1 OR 2(x+2) + 2(x-1)
simplify: 2x + 4 + 2x - 2
4x +2
Plug 5 into x: 4(5) + 2
Answer: 22
Method 2:
plug in x to get the sides: 7 and 4
now add: 7 + 7 + 4 + 4 OR 2(7) + 2(4)
simplify: 14 + 8
Answer: 22
The perimeter of the rectangle when x = 5 is 22 units.
What is perimeter?Its the sum of length of the sides used to made the given figure.
The perimeter is all the sides of any polygon added up.
WE know that rectangle has 4 sides, but we only need two sides to solve because a rectangle has symmetry
Given that A rectangle has side lengths x + 2 and x - 1.
Then plug in x to get the sides: 7 and 4
Now add:
7 + 7 + 4 + 4
OR
2(7) + 2(4)
Then simplify:
14 + 8
22
Hence, the perimeter of the rectangle when x = 5 is 22.
