2. the average distance from the sun to the planet mercury is about 58,000,000 km. the diameter of a human hair is about 0.0025 cm.
(a) what is the distance from the sun to mercury written in scientific notation?
(b) what is the diameter of a human hair written in scientific notation?
(c) in comparing the measurements in parts (a) and (b), what else must be done before a comparison is made?

Asap! i'm not good math and i'm lost.

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?

If you measured the width of a window in inches and then in feet with measurement would you have the greater number of units
