Answer: Multiplicative rate of change in the voting in annual elections in Miller country.
Step-by-step explanation:
Given: In Miller county, the voting in annual elections have gone down by a consistent percentage each year and can be modeled by the function
Since, the above expression is an exponential function. [ ∵ t is the exponent ]
The standard exponential function is given by :-
,where P is the initial amount , b is the multiplicative rate of change with respect to time period t.
As compare to the given expression, we get b= 0.94, which is the multiplicative rate of change in the voting in annual elections in Miller country.

Answer:
The probability that the household has only cell phones and has high-speed Internet is 0.408
Step-by-step explanation:
Let A be the event that represents U.S. households has only cell phones
Let B be the event that represents U.S. households have high-speed Internet.
We are given that 51% of U.S. households has only cell phones
P(A)=0.51
We are given that 70% of the U.S. households have high-speed Internet.
P(B)=0.7
We are given that U.S. households having only cell phones, 80% have high-speed Internet. A U.S household is randomly selected.
P(B|A)=0.8
Hence the probability that the household has only cell phones and has high-speed Internet is 0.408
