52 Jessie was conducting an experiment with bacteria. She started with 12 cells, on the second day she had 48 cells, and 192 cells by the third day. Assuming that this pattern continues, what is the recursive rule that could be used to determine the number of bacteria cells that Jessie observed? A a1 = 12, an = 12an-1 C a1 = 1, an = 12an-1 B a1 = 1, an = 4an-1 D a1 = 12, an = 4an-1 53 Assuming that the following students all conducted the same experiment, which of them would you expect to be closest to the theoretical probability? Joey conducted 22 trials. James conducted 68 trials. . Michelle conducted 50 trials. A Joey C Michelle B James D There is not enough information given
