Question Solved1 Answer 7. The number of large) inclusions in cast iron follows a Poisson distribution with a mean of 2.5 per cubic millimeter. Approximate the following probabilities (a) Determine the mean and standard deviation of the number of inclusions in a cubic centimeter (cc). (b) Approximate the probability that fewer than 2600 inclusions occur in a cc. (c) Approximate the probability that more than 2400 inclusions occur in a cc. (d) Determine the mean number of inclusions per cubic millimeter such that the probability is approximately 0.9 that 500 or fewer inclusions occur in a cc.

Sales performance. A chain that specializes in healthy and organic food would like to compare the sales performance of two of its primary stores in the state of Massachusetts. These stores are both in urban, residential areas with similar demographics. A comparison of the weekly sales randomly sampled over a period of nearly two years for these two stores yields the following information: Does it appear that one store sells more on average than the other store?

The amount of medicine m in the blood during a four-hour treatment is given as me2t = 3t. Determine when the amount of medicine reaches maximum. When the time is such that 3 − 2me2t = 0 When the time is such that e2t = 0 When the time is such that (3/me^2t)=0 When the time is such that me2t = 0

JAVA language Given a sorted list of integers, output the middle integer. A negative number indicates the end of the input (the negative number is not a part of the sorted list). Assume the number of integers is always odd. Ex: If the input is: 2 3 4 8 11 - 1 the output is: Middle item: 4

8.50. An alpha particle of mass 4 u moving with a velocity 2000 m/s collides with a carbon atom of mass 12 u at rest. The alpha particle is scattered through an angle of 30°. Considering the collision to be perfectly elastic, calculate the velocities of both particles after collision and the scattering angle of the recoiling carbon. Describe this collision in the CMCS.

Show that if A and B are matrices which don’t commute, then eA+B = eAeB, but if they do commute then the relation holds. Hint: Write out several terms of the infinite series for eA, eB, and eA+B and do the multiplications carefully assuming that A and B don’t commute. Then see what happens if they do commute.
