Samantha and luis are attempting to determine how many library books each seventh grade student checks out at the same time. samantha surveys every other seventh grade student leaving the library. she samples a total of 40 of the 200 seventh graders. luis samples 30 of the 200 seventh grade students at random in the school cafeteria. whose sample is the most random? luis because his sample is taken from the population of all seventh graders luis because he samples fewer students samantha because she samples more students samantha because her sample is taken from the population of students who use the library

Luis, because his sample is taken from the population of all seventh graders. However, Samanthan has the advantage of having a bigger sample, and that makes it more representative.

Step-by-step explanation:

Taking the sample of the library as Samantha did, is biased, because most of the students there is checking a book, and the aim of the study is not only the ones that use the library, but in general the seventh grade students.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

the answer would be 44.79
