- The Corona Virus, that started to spread in many countries in early 2020, is more contagious than the common flu. Many people are infected, and many of the infected died. The number of deaths resulting from the coronavirus can be calculated as a result of the infection rate and the mortality rate. The infection rate is the number of persons in a population of 1,000,000 people who are likely to get infected. For this exercise, we assume the infection rate ranges from 10 to 25 people per million (PPM). Likewise, we assume the mortality rate (the death rate) ranges from 1000 to 2500 people per million infected (PPMI). These rates are doubled for a susceptible population (that is people who are above 60 or have other health issues). Given these data, answer the following questions. For each question, always start with the original values given here. 1) In a country with a population of 18 million, 30% of the population is above 60 years of age and the other 5% of the total population are…arrow_forward#3arrow_forwardSimplified form of F=y +x y +y x z isarrow_forward
