### A large number N of people are subjected to a blood investigation. This investigation can be organized in two ways. (1) The blood of each person is investigated separately. In this case N analyses are needed. (2) The blood of k people are mixed and the mixture is analysed. If the result is negative, then this single analysis is sufficient for k persons. But if it is positive, then the blood of each one must be subsequently investigated separately, and in toto for k people, k + 1 analysis are needed. It is assumed that the probability of a positive result (p) is the same for all people and that the results of the analysis are independent in the probabilistic sense. What is the probability that the analysis of the mixed blood of k people is positive? What is the expectation of the number of analysis necessary in the second method of testing? For what k is the minimum expected number of necessary analysis attained?" Nefissi8u 2021-11-22 Answered

### The graph shows one of the six basic functions of graphs and a ransformation of the function. Describe the transformation. Then use your description to write an equation for the transformation.  ambiguit 2021-11-22 Answered

### Answer true or false to each of the following statement and explain your answer. In using the method of transformations, a transformation of the predictor variable will change the conditional distribution of the response variable. kdgg0909gn 2021-11-22 Answered

### Determine whether or not the following transformation T : V → W is a linear transformation. If T is not a linear transformation, provide a counter example. If it is, then: (i) find the nullspace N(T) and nullity of T, (ii) find the range R(T) and rank of T , (iii) determine if T is one-to-one, (iv) determine if T is onto. $$\displaystyle{T}:{R}^{{2}}→{R}^{{2}}{d}{e}{f}\in{e}{d}{b}{y}{T}{\left({x},{y}\right)}={\left({x}+{1},{y}\right)}$$ veudeje 2021-11-22 Answered

College Math problems only seem challenging at first, yet what they truly represent is not much harder than high school Math with some equations that are closer to the engineering approach. Approaching your college math helper is essential because your questions may just have to be worded differently. Regardless if you are dealing with equations or need answers to your college math questions, taking a look at college math equations will let you see things differently. Approach college math answers step-by-step. The majority of college math problems with answers represented here will be similar to what you already have.
