What does the diagram show about phases and the phase of the substance as it is heated? check all that apply. the substance is a gas at more than 2,000°c. the particles are close together but move in different directions between 0°c and 2,200°c. the attractions between the particles increase in region 2. the speed of the particles increases in region 5. the substance does not exist as a solid. a graph of temperature versus time, with time in minutes as the horizontal axis and temperature in degrees celsius as the vertical axis. 5 sections of line are labeled: 1 from 0 minutes, negative 80 degrees to 1, negative 40. 2: from 1 negative 40 to 3, negative 40. 3: from 3, negative 40 to 7, 360. 4: from 7, 360 to 15, 360. 5: from 15, 360 off the top at the chart at 18 minutes.

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
