Of the last three chapter tests given in an astronomy class, 2 students passed all three tests, 6 students passed two tests, and 9 students passed one test. If a single student is picked at random, what is the probability that the student passed two tests or passed one test?

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.

Aline passes through the points (5,4) and (2.1). part a.) what is the slope of the line that passes through these points? show work. part b.) what is the equation of the line that passes through these points. show work. part c.) where does the line intercept on the x& y axis? show work

2and 3 are angles. complementary vertical congruent supplementary
