Gretchen wants to run a test to discover whether glass, copper, wood, or plastic conduct electricity. she sets up a circuit connecting a battery to a light bulb, with a small gap she will use to test the conductivity of the different substances. one at a time, she connects the circuit with the chosen test material, and records whether or not the light bulb comes on. is this a good experimental design? a) no, because she is testing too many things at once. b) no, since we don't know the results of the experiment. c) yes, because all of the materials gave the results she predicted. d) yes, because she is only changing one piece of the experiment at a time.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
