Percentage increase/decrease is given by (the difference ÷ original value) × 100
The decrease in value is 16500 - 14000 = 2500
The percentage decrease = (2500÷16500) × 100 = 15.2%
Answer:
d. 52.5 million cases
Step-by-step explanation:
from the data output in the question, we have the regression equation to be
log y = -151.281 + 0.076577x
y is the number of hiv cases which is in millions
x is the year of the hiv case
x = 1998
we put the value of x in the regression equation
log y = -151.281 + 0.076577(1998)
log y = -151.281 + 153.000846
log y = 1.719846
since the result is in log form,

y = 52.5 million cases

352 divided by 25 = 14.08 so technically 14 r 8
It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
