a) adults 18 and older
b) Everyone with a telephone
c) Some people do not have telephones.
Step-by-step explanation:
a) Identify the population of interest
The population of interest is the population that will be studied. For this survey subjects were adults aged 18 and older who were interviewed by telephone. Therefore, the population of interest would be everyone in the nation that is 18 years and older.
b) The company performs its surveys by phoning numbers generated at random from a computer program. What is the sampling frame?
The sampling frame is the source from which a sample is drown. In this case, the sample was selected by a computer program which generated phone numbers, therefore, the sampling frame is everyone with a telephone.
c) What problems, if any, would you be concerned about in matching the sampling frame with the population?
The main problem with this sampling frame is that people who don't have telephones have zero chance of being selected. Therefore, this subset would be the main concern.

Check the picture:
Rotating JKL 180° with respect to the origin, and translating it 1 unit up, we get J'K'L'.
That is, the 2 triangles match perfectly.
Answer:
<span>△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions.</span>
