Answer:
Option d is the right answer.
Step-by-step explanation:
Given that X, the life of a certain brand of battery is normally distributed, with mean 128 hours and standard deviation 16 hours.
Required probability = Prob that a battery you buy lasts at most 100 hours
=P(X<100)
Convert x into z
as
Z =

Answer:
Growth when: b>1.
Decay when: 0<b<1.
Step-by-step explanation:
Any function in the form , where a > 0, b > 0 and b not equal to
is called an exponential function with base b.
If 0 < b < 1 this is an example of an exponential decay.
The general shape of an exponential with b > 1 is an example of exponential growth.
Hence,
An exponential function is expressed in the form , The relation represents a growth when b >1 and a decay when 0<b<1.
