How would you find out how many sixth through eighth grade students are interested in joining a running club? explain how to choose a sample that will give you a good representation of a whole population.

The sample should be a random sample from the entire set of students and should include enough students to be reliable. Small samples have more variation, which leads to less reliable inferences.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

if you was gonna solve for a, a is a   < -12
