10. Determine whether the following argument is valid or invalid. Include a truth table and a few words explaining why the truth table shows validity or invalidity. If 12 divides 709,438 then 3 divides 709,438. If the sum of the digits of 709,438 is divisible by 9 then 3 divides 709,438. The sum of the digits of 709,438 is not divisible by 9. Therefore, 12 does not divide 709,438.

A database of spontaneous adverse reaction reports contains a total of 2 million reports. Among them, there are 80,000 (4%) dealing with CNS side effects (for all drugs) and a total of 40,000 (2%) dealing with painkillers (all reactions). There are a total of 1,600 reports dealing with CNS side effects as a side effect of painkillers. Which of the following statements is CORRECT? A) The over-frequency described is not significant and thus one can not conclude one by one about the relationship between painkillers and CNS side effects. B) Proportional reporting ratio is 5, ie. it is a signal. C) Proportional reporting ratio is 0.50, which is not high enough to raise suspicion of a signal. D) Proportional reporting ratio is 1 and thus it is not a signal. E) Odds ratio for the association is 2, ie there is strong knowledge of a causal relationship between the use of painkillers and risk of CNS side effects.
Which of the following statements can be right: (1). If x = O(n4), y = O(n2), then x/y = O(n2). (2). If x = Θ(n4), y = Θ(n2), then x/y = Θ(n2). Only (1) is right. Only (2) is right. Both (1) and (2) are right. (D). Neither (1) nor (2) is right
You have been provided with the data for the last day of the previous month so you can start by calculating the daily data for the first of the month For the first state for the first day of the month (not the last day of the previous month) enter the following formula into the upper cell for the column for “Daily Confirmed cases” = Current day’s cumulative Confirmed cases – the Confirmed cases for the day before (i.e. the last day of the month). This will yield the number of daily confirmed cases for the first of the month. (Use Excel cell referencing in the formulas)
