A large File F is transformed from host A to host B. There are N Layer 3 devices between them. Assuming the links are uncongested. if the size of each segment was S and the size of the header was h and the transmission rate for each link is R. write the equation (formula) of the total delay assuming that the propagation delay for each link is P& assuming each Layer 3 device uses store-and-forward packet switching NOTE: briefly verify your answers (showing the results only is not acceptable).

A high school principal wanted to know how the teachers at her school felt about early dismissal for Homecoming. She put the names of the 114 faculty in a hat and randomly selected 30 of the names. She gave questionnaires to those 30 people asking whether they agreed or disagreed with the following statement: "Valuable learning time should not be sacrificed for extracurricular social activities." The questionnaires were filled out anonymously. Her conclusion was that 80% of the faculty were opposed to early dismissal for Homecoming. What is the biggest flaw in the study? Confounding variables The setting may discourage honest responses The wording of the question Selection bias Participation bias.

A group of students at a high school took a standardized test. The number of students who passed or failed the exam is broken down by gender in the following table. Determine whether gender and passing the test are independent by filling out the blanks in the sentence below, rounding all probabilities to the nearest thousandth. Since P( female pass )= and P( female )= the two results are so the events are.

A genetic disease is devasting the squirrel population. When the temperature falls below freezing squirrels that are homozygous for the rozen allele (f) immediately fall asleep. There are only two alleles for this gene in the olemiss squirrel population (f, F). As the landscape nanager for campus, you find 18 sleeping squirrels when the temperature drops. There is an estimated total squirrel population of 2000. Estimate the percentage of animals heterozygous carriers in this population? (Assume Hardy-Weinberg equilibrium, Format your answer o 2 decimal places.).

A generalized transducing phage is used to infect wildtype prototrophic E. coli, and the lysate is used to transduce an abcderecipient. The recipient cells are plated on minimal medium supplied with the indicated compounds. The results are shown in the following table. (Note that aindicates a requirement for compound A, etc.) What can you conclude about the order of these genes? Three of the genes are closely linked and have the order bdc, while genes a and e are not closely linked to any other genes. The gene order of four of the genes is cead, but the placement of b is unknown. Genes b,c and d are linked, but their order cannot be determined. Genes a and e are not closely linked to any of the other genes. Genes a,c,d and e are closely linked, but their order cannot be determined with certainty, while gene b is not closely linked to this group..
