The company manufactures its own GPS units, which are smaller than those of any other competitor and include a proprietary battery that lasts 200% longer than any other competitor's battery and that TerraLoc manufacturers on-site. TerraLoc also has developed proprietary software that is much faster and more precise than that of any competitor. When developing the proprietary battery, TerraLoc decided to manufacturer the battery in-house to reduce the possibility that the company it outsourced the battery manufacturing to might reverse engineer the battery and sell a similar product to competitors. This possibility was especially troubling given that the company expected a significant increase in demand due to the improved battery life. Additionally, TerraLoc sells its products and services through its own direct sales force to ensure that its representatives highlight the longer battery life of TerraLoc's units.TerraLoc's decsion to manufacture the battery in-house is most consistent with which theory(s) of vertical integration?a. Firm capability-based explanationsb. Alliance-based explanationc. Opportunism-based explanationsd. Flexibility-based explanations Syllabaries does Native American languages developed from From the given electron configurations, predict which one is for a representative element?A)1s22s22p63s23p64s2B)1s22s22p63s23p63d74s2C)1s22s22p63s23p63d64s2D)1s22s22p63s23d5 Suppose that T is a one-to-one transformation, so that an equation T(u)=T(v) always implies u=v. Show that if the set of images {T(v1)......T(vp)} is linearly dependent, then {v1......vp} is linearly dependent. This fact shows that a one-to-one linear transformation maps a linearly independent set onto a linearly independent set (because in this case the set of images cannot be linearly dependent). A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. If both children are of blood type M, list all of the possible parental phenotypes Crossing a BB parent with a bb parent results in When you ask for directions to a post office you are asking aboutA. cartographyO B. placeC.

Use 3.14 for A human gene carries a certain disease from the mother to the child with a probability rate of 34%. That is, there is a 34% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has three children. Assume that the infections of the three children are independent of one another. Find the probability that at least one of the children get the disease from their mother.Answer the following questions:State the complement of the event "At least one of the children get the disease from their mother".Find the probability of the complement. Round your answer to four decimalsFind the probability that at least one of the children get the disease from their mother.
