I need help only on number 3
1 answer:
Gaps have no data in them. So the range 1-2 is a gap.
Clusters are groups of data that are right next to each other.
So the range 3-6 on your dot plot is a cluster, because there is a group of data there with no gaps.
Peaks are the greatest amount of data in the dot plot. 0 and 5 are the peaks because they both have the most data, 4.

Answer:
The coordinates of the vertices of the reflected figure are :
R' is (5 , -2) , S' is (3 , 5) , T' is (-7 , 6) ⇒ the right answer is (d)
Step-by-step explanation:
* When you reflect a point across the line y = x, the x-coordinate
and y-coordinate change their places.
- If the point is (x , y) then its image is (y , x)
* If you reflect over the line y = -x, the x-coordinate and y-coordinate
change their places and their signs
- If the point is (x , y) then its image is (-y , -x)
* Lets study the matrix of the reflection about the line y = x
- The matrix of the reflection about the line y = x is
- Because the x-coordinate and y-coordinate change places.
* Now lets solve the problem
- We will multiply the matrix of the reflection about y = x
by each point to find the image of each point
- The dimension of the matrix of the reflection about y = x
is 2×2 and the dimension of the matrix of each point is 2×1,
then the dimension of the matrix of each image is 2×1
∵ The point R is (-2 , 5)
∴
∴ R' is (5 , -2)
∵ The point S is (5 , 3)
∴
∴ S' is (3 , 5)
∵ The point T is (6 , -7)
∴
∴ T' is (-7 , 6)
* Lets look to the figures to find the right answer
∵ The R' is (5 , -2) , S' is (3 , 5) , T' is (-7 , 6)
∴ The right answer is (d)
