During data transfer, which of the following is one of the main responsibilities of the receiving host? A. Throughput B. Acknowledgment C. Encapsulation D. Segmentation
9. From Equation 2.15, $\Delta t_1 = L/(v-u)$, and from Equation 2.16, $\Delta t_2 = L/(c+u)$. $$\Delta t = \Delta t_1 + \Delta t_2 = \frac{L}{v-u} + \frac{L}{c+u} = \frac{\Delta t_0}{\sqrt{1-u^2/c^2}}$$ With $\Delta t_0 = L_0/v' + L_0/c$ and $L = L_0\sqrt{1-u^2/c^2}$, this becomes $$\frac{1}{v-u} + \frac{1}{c+u} = \frac{1}{1-u^2/c^2} (\frac{1}{v'} + \frac{1}{c})$$ Solving for $v$, we obtain $$v = \frac{v'+u}{1+v'u/c^2}$$
1. Let A be an m by n matrix and B be an n by n matrix. (a) If rank(A) = nullity(A), prove that n is even. (Note: nullity(A) = dim Nul(A)). (b) Prove that Nul(B) \subset Nul(AB) (i.e., every vector in Nul(B) is also in Nul(AB)). (c) Prove that dim Nul(B) \le dim Nul(AB). (d) Prove that rank(AB) \le rank(A).

A random sample of runners aged 15 to 24 years participating in a marathon provided data for a correlation with the x variable being age and the y variable being completion time. The proportion of variation in completion time that can be explained by the variation in age was approximately 0.663. What was the value of the sample linear correlation coefficient? 0.663 0.814 0.440 0.902
