Alarge company wants to administer a satisfaction survey to its current customers. using their customer database, the company randomly selects 8080 customers and asks them about their level of satisfaction with the company.
identify which of these types of sampling is used: random, systematic, convenience, stratified, or cluster.

Random

Step-by-step explanation:

Here , the company wants to administer a satisfaction survey to its current customers.

So , Population → All current customers

Using their customer database, the company randomly selects 80 customers , it means each customer had the same chance to get selected.

Hence, the type of sampling is used : Random sampling

Hence, the correct answer is "Random" .

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
