The value of 5t will be 15.55
Step-by-step explanation:
Given equation is;
9t = 27.99
As it is stated that the relationship is constant, therefore, we will find the value of t by dividing 27.99 by 9
Now, we will put t=3.11 to find 5t.
The value of 5t will be 15.55

Answer:
a) X ~
b) μ = 100/3
c)
d) A battery is expected to last 100/3 months (33 months and 10 days approximately).
e) For seven batteries, i would expect them to last 700/3 months (approximately 19 years, 5 months and 10 days).
Step-by-step explanation:
a) The life of a battery is usually modeled with an exponential distribution X ~
b) The mean of X is μ = 1/0.03 = 100/3
c) The standard deviation is
d) The expected value of the bateery life is equal to its mean, hence it is 100/3 months.
e) The expected value of 7 (independent) batteries is the sum of the expected values of each one, hence it is 7*100/3 = 700/3 months.
