A translation is shown on the grid below in which triangle A is the pre-image and triangle B is the image. On a coordinate plane, triangle A is shifted 6 units to the right to form triangle B.

Which rule describes the x-coordinates in the translation?
x + 0
x + 6
x – 6
x + 4

c. Cluster random sample

Step-by-step explanation:

Missing word "every participant in those meetings. What type of sample is this? a. Simple random sample, b. Stratified random sample, c. Cluster random sample, d. None of the above"

In the cluster sampling, researchers will divide a certain population into smaller groups which is known as clusters, then, they randomly select among these clusters to form a sample. In cluster sample, the clusters to be included are selected at random and all members of the cluster are included.
