Answer:
If a person drink soda, the person will likely answer the question of the survey and SOME PEOPLE MIGHT NOT BE ONLINE TO PARTICIPATE IN THE SURVEY, YET THEY DRINK SODA DAILY.
Step-by-step explanation:
From the question above we are given that the survey of 2028 responses was conducted on the internet through AOL. In the response to the question, " How often do you drink soda?" Only 33% said they drink soda almost every day.
The following should be noted down;
(1). This survey is questionable, (2). This survey is not representative and (3). It is a voluntary response sample.
Because of the third point above, it can be said that the survey response is not representative.
SOME PEOPLE MIGHT NOT BE ONLINE TO PARTICIPATE IN THE SURVEY, YET THEY DRINK SODA DAILY.
Answer:
The options are not shown, so i will answer this in a general way.
When we have a number like:
0.7979....
The steps to writing it as a fraction are the following ones:
1) First, you need to notice the repeating decimals.
In this case is easy to see that the repeating decimals are two, 7 - 9
2)we can multiply this number by 10^n, where n is the number of repeated decimals, in this case n = 2
10^2 = 100
then:
0.7979...*100 = 79.7979...
Now we can subtract the original number:
79.7979... - 0.7979 = 79
And this is equivalent to have:
0.7979..*100 - 0.7979... = 0.7979..*99 = 79
Then we know that if we multiply our number by 99, the outcome will be an integer.
Then we can multiply and divide by the same number (this is equivalent to multiply by one) as follows:
0.7979...*1 = 0.7979..*(99)/(99) = (0.7979..*99)/99 = 79/99
Then:
0.7979... = 79/99
C = 0.3*-2.7 = -0.81
Hope it helps:)
