Step 1
Given: f(x)=0.99286x(1),
where x is the number of dollars of country A
let y=f(x)(2) is the number of dollars of country B
therefore, x=f1(y)
Step 2
substitute Eq'n(2) in Eq'n(1)
y=0.99288x
x=y0.99288
f1(y)=1.00717y
Substitute x insted of y therefore,
f1(x)=1.00717x

According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal.f(x)= where X.μ=σ=. Find the probability that the individual lost more than 8 pounds in a month.Suppose it is known that the individual lost more than 9 pounds in a month. Find the probability that he lost less than 13 pounds in the month.
