2 answers:
Answer:
B. y= - (0.25)^x+ 4
C. y= - (3)^x+4
Step-by-step explanation:
There is no impediment in an exponential function, so all of the have the domain (-infinity, infinity).
In an exponential function in the following format:
The range is (-infinity, b).
So these following functions apply:
B. y= - (0.25)^x+ 4
C. y= - (3)^x+4
A and D have ranges from negative infinity to negative four.

Answer: The probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .
Step-by-step explanation:
The cumulative distribution function for exponential distribution is :-
, where
is the mean of the distribution.
As per given , we have
Average tread-life of a certain brand of tire :
Now , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles will be :
Hence , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .
