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?

true

explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
