If y = 3,125,000e - 0.23x measures the likelihood of an elderly person surviving a fall at home (x is age in years, y is probability of survival), find the following: 2. What are the chances of a 70-year-old surviving a fall at home?
If y = 3,125,000e - 0.23x measures the likelihood of an elderly person surviving a
fall at home (x is age in years, y is probability of survival), find the following:
2. What are the chances of a 70-year-old surviving a fall at home?
3. What are the chances of an 85-year-old surviving a fall at home?
4. At what age do humans reach the 50% mark of surviving a fall at home?

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
