The question gives you two points as part of a triangle RST in an xy-plane. point R (2,3) and point S (5,6). The question is: if the slopes of the three sides must add up to 1, which angle can be a right angle. The answer they give you is none, but wouldnt it be possible for T to be a right angle? If it is placed at (5,3), wouldnt the resulting two slopes be zero and undefined? and then 1+0=1 and you cant add undefined. Maybe having undefined in the equation (1+0+und=1) is breaking a rule

I got through both of the MCs alright, but the last 3 of the FRQs were really tough, considering that I was pretty much lost on number 5 and had to just make something up (I hope that I get some points on that one). The first 3 of the FRQs were really easy though, so I am hoping for a 3 overall. How does everyone else think they did?

Could somebody please help me with this problem? I cant figure it out. Thank you!Suppose psychiatrists use a certain reliable test to diagnose depression in patients. Non-depressed people taking the test score a mean of 10.21 points, but the population variance is unknown. A group of 21 patients diagnosed with depression took the test and scored a mean of 22.12 with a std. dev. of 10.73. The standard error was 2.34. Test the null hypothesis that the patients scored equal to or less than the non-

Two lab students referred to as “X” and “Y” prepared solutions of .8 M, .6 M, .4M, .2 M sucrose, but forgot to label the. After realizing their tremendous error, the assistants randomly labeled the flasks containing these four unknown solutions as flask A, B, C, and D.Design an experiment, based on the principles of diffusion and osmosis, that the students could use to determine which of the flasks contains each of the four unknown solutions.Im lost on this one guys can some

Joyce Chen, whose cookbook popularized dishes that might otherwise have been unknown in the United States, is most famous for culinary techniques she invented. No error.In the above sentence, why is it correct? I mean, should it not be has invented instead of invented at the last part of the sentence?

I am currently studying for the APHG exam on Friday. I am doing all the tips to get a 5 (study vocab, learn the models, etc.). I am just wondering, how did YOU study, and how was the test-taking experience and afterward. Score would be appreciated, but not necessary. You identity is virtually unknown!
