If there was zero error in the experiment, how many points would be on the line? (meaning if the equation for the points was created). I'm thinking that ALL points will be on that line, but I feel like this is a tricky question. The other option is that "there will always be some points that do not go through the line even if there is zero error" I know that in real life nothing is perfect but the question seems to ask about a theoretical situation. What do you guys think?

Hey guy's I'm doing a HW assignment in Stats and I'm stumped on this problem. I'd really appreciate it if someone could explain how to solve it. A professor has recorded exam grades for 20 students in his class, but one of the grades is no longer readable. If the mean score on the exam was 82 and the mean of the 19 readable scores is 84, what is the value of the unreadable scores? Thanks for the help!

I need some help /sci/ A student mistakenly divides a number by 5 instead of multiplying it by 5. The percentage error, the ratio of the amount of the error to the correct value expressed as a percent, is A) 4 B) 25 C) 80 D)96 E) 2400 Thanks in advance

A student wanted to drive from Austin to San Antonio, 80 miles south of Austin on highway I35. Unfortunately, he entered the highway in the wrong direction and drove all the way to Waco — 100 miles north of Austin — before he noticed his error. In Waco, he turned around, drove back to Austin and continued to San Antonio. The whole trip took 5.11 h. What was the student’s average speed dur- ing this trip? Answer in units of mph What was the student’s average velocity during his trip? Take your positive direction to be southbound on I35. Answer in units of mph

Linear algebra

1 more posts in this thread. [Missing image file: photo.jpg]
Does anyone have a linear algebra textbook they'd recommend studying from? The one I'm using for my class, by Leon, feels very poorly organized, and makes referencing certain concepts on the fly difficult. It's up side is that it has wonderful application examples. But the core subject often gets lost amongst the examples. Any suggestions?

Sup /sci/ uni enrolements are coming up, not sure what I want to do, pretty much suggestions thread. ie. do/did you like your major/degree? What was it? Flaws/good things about it? Background info: >good at problem solving, not like crossword shit, but in depth logical puzzle (heard of 3301?) >Currently topping class in physics, and 2nd in maths. >Want to find out shit in the world, why things happen etc, but on a large scale like universe, science related things. >want to create multiple businesses, however don't really want to do business degree as i'd rather just learn that knowledge from free online courses then get a B. in it. >like fixing shit, use to always tear apart and rebuild stuff. I can go into more details if you guys need anything. Pretty much suggesting for decent university majors that might suit. >Not medicine, law, biology, humanitarian type degrees.

I've read about particle detection on Wikipedia, and it is all rather vague. My question is this: how do they detect that yellow spiral? Is it inferred, or are they able to track a sub-atomic particle without affecting its motion?
