Ahigh school student volunteers to present a report to the administration about the types of lunches students prefer. he surveys members of his class and records their choices. what type of sampling did the student use?

convenience sampling is the correct answer.

Step-by-step explanation:

A convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach.

For example: standing at a mall or a grocery store and asking people to answer questions would be an example of a convenience sample.

This type of sampling is also known as grab sampling or availability sampling. There are no other criteria to the sampling method except that people be available and willing to participate.

In addition, this type of sampling method does not require that a simple Random sample is generated, since the only criteria is whether the participants agree to participate.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
