Xvaries directly with y. if x is 16 when y is 20, find x when y is 80.

32

Step-by-step explanation:

16/20 reduces down to 2/5

set 2/5=x/80

cross multiply 160=5x

divide 32=x

check 2/5=32/80

32/80; 16/40; 8/20; 4/10; 2/5

yay 32 is the answer good luck :)

Step-by-step explanation:

The opinions of viewers of one television station are not necessarily representative of the population of a region.

Say a community has a thousand people, not everyone of those people would watch that exact station, among those that do watch which would be a few percentage, only a few also would even care to participate in the said survey.

You can't take a survey based on the responses gotten on just one station
