A blood alcohol concentration of 0.22 corresponds to near certainty, or a 100% pro bability, of a car accident. R 100% 80% 60% 40% 20% R = 6e2.71x 0.05 0.10 0.15 0.20 0.25 Blood Alcohol Concentration Risk of a Car Accident
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Use the formula, the risk is modeled by R = 6e12.77x, where x is the blood alcohol concentration and R, given as a percent, is the risk of having a car accident. to solve, What blood alcohol concentration corresponds to a 7% risk of a car accident? (In many states, drivers under the age of 21 can lose their licenses for driving at this level.)
