How will this transaction affect Aldi as it seeks to expand its presence in the United States? What competitive actions might Aldi take in response to Amazons purchase of Whole Foods?Using concepts and actions explained in this chapter, decide if Aldi is more likely to respond to any strategic actions Amazon might initiate through Whole Foods or if Amazon through Whole Foods is more likely to respond to any strategic actions Aldi takes. Be prepared to justify your decision.In a competitive rivalry sense, explain the actions (strategic and/or tactical) you believe Walmart and Costco will take to respond to Aldis intentions to have 2,500 U.S. stores by 2020 (and if this truly came to light now that we are in 2022, and how many stores actual exist).

Discuss at least two such predictions that have been strongly confirmed by observations. Explain how the detection of "hot Jupiter" extrasolar planets seemed to be a striking inconsistency with the solar nebula theory. Do you think astronomers were justified in modifying the solar nebula theory in the face of such evidence as opposed to discarding the theory altogether? It is observed that in the cells of a color-blind male child one Barr-body is present. The child has a maternal grandfather who was also color-blind. The boy's mother and father are phenotypically and karyotypically normal. Provide the sex chromosome genotype of the mother, father, and child to support the genetic attributes of the Barr-body positive child and explain specifically how this could occur. Hint: Assume X chromosome inactivation occurs after the development of the retina and therefore is NOT involved the phenotype of color-blindness. Also, remember colorblindness is a recessive trait. A fluid in a fire hose with a 46.5 mm radius, has a velocity of 0.56 m/s. Solve for the power, hp, available in the jet at the nozzle attached at the end of the hose if its diameter is 15.73 mm. Express your answer in 4 decimal places. 1. (a) Let A and B be two events. Suppose that the probability that neither event occurs is 3/8. What is the probability that at least one of the events occurs? (b) Let C and D be two events. Suppose P(C)=0.5,P(CD)=0.2 and P((CD) c)=0.4 What is P(D) ?
