The answer is:
[A]: "
" .
________________________________________Given:
2/ (7x) = 6/5;
→ (6/5) * (7x) = 2 ;
42x / 5 = 2 ;
42x = 2*5 ;
42x = 10 ;
42x /42 = 10/42 ;
x = 10/42 = (10÷2) / (42÷2) = 5/21 ;
x =
;
→ which is:
Answer choice: [A]: "
" .

Answer:
c. Asking people leaving a local election to take part in an exit poll
Step-by-step explanation:
Asking people leaving a local election to take part in an exit poll best represents the highest potential for nonresponse bias in a sampling strategy because of the importance of the local election compared to the exit polls.
It is worthy of note that nonresponse bias occurs when some respondents included in the sample do not respond to the survey. The major difference here is that the error comes from an absence of respondents not the collection of erroneous data. ...
Oftentimes, this form of bias is created by refusals to participate for one reason or another or the inability to reach some respondents.
Answer:
c and d are correct
Step-by-step explanation:
The simplest form of the given expression can be written as -5x² + 25x - 3.
The given parameters:
2x(x + 6) - 7x² + (13x - 3)
The given expression can be simplified as follows;
2x(x + 6) - 7x² + (13x - 3)
= 2x² + 12x - 7x² + 13x - 3
<em>collect similar terms together</em>
= (2x² - 7x²) + (12x + 13x) - 3
= -5x² + 25x - 3
Thus, the simplest form of the given expression can be written as -5x² + 25x - 3.
