K-12 algebra 2. ! for a research project, students are asked to study how often students at an online high school look at social media while doing schoolwork. a) give an example of a question she could ask on her survey b) how could sofie select a simple random sample of students to take her survey? c) she gives out 80 surveys but receives only 32 completed surveys. what are the sample and population for sofies research? d) of the 32 students who completed surveys, 16 said they use social media while doing schoolwork. if sofie uses only the completed surveys, what conclusion could she make about the percent of all high school students who use social media while doing schoolwork?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
