During Samuel’s experiment, the experimental probability was 0.25. What else must be true about the experiment? The experimental probability of the outcome is 1/4

The experiment has four possible outcomes.

The theoretical probability of the outcome is 1/4

four trials were run during the experiment.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297

Atriangle has verticals at b(-3,0), c(2,-1), d(-1,2). which transformation would produce an image with verticals b”(-2,1), c”(3,2), d”(0,-1)?

The value of cos 30° is the same as which of the following?
