ANSWER

D. $24 - 2d$

EXPLANATION

Marjorie bought a total of 24 bottles of juice.

If she opens and drinks 2 bottles each day, then

at the end of the first day,the number of unopened bottles will be;

$= 24 - 2(1) = 22$

at the end of the second day,the number of unopened bottles will be;

$= 24 -2 (2) = 20$

at the end of the third day,the number of unopened bottles will be;

$= 24 - 2(3) = 18$

At the end of d days,the number of unopened bottles will be;

A national organization sets out to investigate the change in prevalence of HIV since the last census in 2010. A total of 4,706

nikitadnepr [17]

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%.
