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?

21 i watched a 3 hr vid explaining it

step-by-step explanation:

du what else would it be

brainliest

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the answer is 62.8 cubic units

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
