You have just finished investigating a disease outbreak at a summer picnic party. Out of 100 total attendees, a total of 50 individuals became ill. Of these, 48 individuals developed vomiting and nausea 4 to 6 hours after the picnic. No one developed a fever. Two elderly individuals, however, had complications leading to more severe form of the illness and had to be hospitalized. After the lab tests were conducted, the infectious agent was identified. The lab tests also revealed that 75% of all the individuals attending the party had been infected What is the pathogencity of the infectious agent?
a. (2/50) * 100
b. (2/75) * 100
c. (50/75) * 100
d. (75/100) * 100
e. None of the above

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
