In order to assess the opinion of students at the ohio state university on campus safety, a reporter for the student newspaper interviews 15 students he meets walking on the campus late at night who are willing to give their opinion.
1) the sample is:
a) all students at universities with safety issues.
b) the 15 students interviewed.
c) all students approached by the reporter.
d) all those students walking on campus late at night.
2) the method of sampling used is:
a) the gallup poll.
b) simple random sampling.
c) voluntary response.
d) a census.
3) the sample obtained is:
a) a probability sample of students with night classes.
b) a stratified random sample of students feeling safe.
c) a simple random sample of students feeling safe.
d) probably biased.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
