To determine customer opinion of their pricing, home depot randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. what type of sampling is used?

Cluster sampling

Step-by-step explanation:

A cluster sampling is a kind of random sampling technique in which the researcher splits the whole population into distinct sets known as clusters.

After that, he choose a random sample of clusters from the population and do analysis on it.

In the given situation, the objective of survey : "To determine customer opinion of their pricing:".

He first divides the number of check out lines according to weeks and randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. .

(Here , check out lines = clusters )

Therefore , the type of sampling is used = Cluster sampling

the image of (6, 9) under a dilation is (4, 6). the scale factor is

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
