Assume that police estimate that 30% of drivers do not wear their seatbelts. They set up a safety roadblock, stopping cars to check for seatbelt use. They stop 25 cars during the first hour. a. Find the mean, variance, and standard deviation of the number of drivers expected not to be wearing seat belts. Use the fact that the mean of a geometric distribution is μ= 1 p and the variance is σ2= q p2. b. How many cars do they expect to stop before finding a driver whose seat belt isn't buckled

Ответ:
C.Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input.
Step-by-step explanation:
The domain of a function is all the values that can be put into the independant variable in order to value the dependant value, this basically means that the domain is all the values that you can give to the "x", and since you can put any value into the "x"the domain of that function is all the real numbers.
