before starting a summer jobs program, the school board conducted a survey at various schools. they interviewed
30% of the high school students to know whether they would participate in the program. the results are shown in the graph

is this sampling method valid? if so, how many of 750 students of various high schools are likely to participate in this
program?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

Any pictures or something i need more info
