Answer:

Cluster sampling.

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

People divided into groups, by households.

Each member of the households(group) is surveyed, so cluster sampling.

Answer:

m\angle 1=95^{\circ}

Step-by-step explanation:

If we drew an auxiliary line parallel to line p and line q that intersects the vertex of \angle 1, we would form three angles, one of them being

The largest of these angles corresponds with the angle marked as 148^{\circ}.

The angle on the bottom right corresponds with the angle next to the one marked as 63^{\circ}. Therefore, its measure is 180-63=117^{\circ}.

Since there are 360^{\circ} in a circle, we can now write the following equation:

m\angle 1+117+148=360,\\m\angle 1=\fbox{$95^{\circ}\checkmark$}.
