Assume that trees are subjected to different levels of carbon dioxide atmosphere with 6% of the trees in a minimal growth condition at 360 parts per million (ppm), 13% at 450 ppm (slow growth), 46% at 560 ppm (moderate growth), and 35% at 640 ppm (rapid growth). What is the mean and standard deviation of the carbon dioxide atmosphere (in ppm) for these trees

James was playing a game with his friends. he won 35 points. then he lost 15, lost 40 and won 55. how did he come out

Idon't want to fail summer school. the probabilities of contamination in medicine capsules due to the presence of heavy metals and different types of microbes are given in the table. the probability of capsule b having microbial contamination is (the same as, greater than, less than) the probability of capsule d having it.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x′y′z′, with vertices x′(4, -2), y′(4, -3), and z′(1, -4). the type of transformation that triangle xyz undergoes is a . triangle x′y′z′ then undergoes a transformation to form triangle x′y′z′, with vertices x″(4, 2), y″(4, 3), and z″(1, 4). the type of transformation that triangle x′y′z′ undergoes is a .
