Explanation & Answer
3x - 4x^1/2 + 1 = 0
Let a=x^1/2, then a^2=x
So 3a^2-4a+1=0
(3a-1)(a-1)=0
a=1/3 or a=1
Therefore x^1/2=1/3 or x^1/2=1
x=1/9 or x=1

Calculate the crude rate
of heart disease for each of the two countries. Suppose that you want to
compare the rate of heart disease in India to that in the United States. You
know that age is an important risk factor for heart disease. Examine the age
distribution of each country’s population.
·
Should you use the two
crude rates to compare the two countries? Why or why not?
·
Calculate an
age-adjusted rate for heart disease in each country. Use the age distribution
of the entire world as your standard.
·
Based on these answers,
would you say that the age differences between India and the United States
account for the entire difference in crude heart disease rates between the two
countries? Why or why not?
