The answers to the numbers are shown below.
1.) Divide both sides by two to yield an answer of n > 7.
2.) Cross multiply by multiplying the denominator, 5, by 11. This gives an answer of n ≥ 55.
3.) Divide both sides by -3. Since we have an operation involving a negative number, we invert the sign. Thus, the answer is y ≥ 6.

Answer:
As can be seen, there has been a rise in the proportion of the population with HIV positive, from 7.5% to 9.94%.
Step-by-step explanation:
Given that a national organization sets out to investigate the change in prevalence of HIV since the last census in 2010, ya total of 4,706 participants were interviewed and a total of 468 responses were confirmed to be HIV positive, assuming that the data from the census indicated that the prevalence of HIV in the particular population was 7.5%, to determine if the proportion of the prevalence of HIV has changed (is equal to 7.5%) the following calculation should be performed:
4706 = 100
468 = X
468 x 100/4706 = X
46,800 / 4,706 = X
9.94 = X
Therefore, as can be seen, there has been a rise in the proportion of the population with HIV positive, from 7.5% to 9.94%.
