The severe limitation of using the internet for primary research is that a sample universe composed solely of internet respondents represents a potential bias.
Given options 1)The data on the Internet are usually outdated.
2) The educational qualifications of the respondents of surveys on the Internet cannot be identified accurately.
3) A sample universe composed solely of Internet respondents represents a potential bias.
4)Secondary data cannot be accessed on the Internet for conducting research.
5) Using the Internet for primary research is the most expensive way of conducting primary research.
We have to choose most appropriate option which shows the severe limitation of using internet for primary research.
The most appropriate option is option third which is that a sample universe composed solely of internet respondents a potential bias
There is biasness because on internet people gives their own opinion and reviews and don't think about reality. The data may have been collected for the research according to researcher's priority. The data may be outdated but it is of our choice whether we use that data or not because generally the date is given on the internet. We can also access secondary data on the internet. Using internet in research is not so expensive because some organisation provides study materials to researchers themselves.
Hence the limitation of using the internet for primary research is that a sample universe composed solely of internet respondents a potential. bias.

A= x(4x-2) then distribute the x to get A=4x²-2x
Then plug in the 8 and get A=4(8)²-2(8)
A=256-16
A=240
Answer:
Third side = 7
Step-by-step explanation:
x = third side:
Hope this helps
Answer:
-z( 2z^3-5z^2+9z-1)
Step-by-step explanation:
Apply exponent rule: a^b+c=a^b*a^c
z^2=zz
z^3=z^2*z
z^4=z^3*z
Factor out common term z:
-z(2z^3-5z^2+9z-1)
Let us assume the larger number = x
Let us assume the smaller number = y
Then
x + y = 3 3/4
x + y = 15/4
And
x/3 = (2y/3) + 1/2
x = [3 * (2y/3)] + (3/2)
= 2y + (3/2)
Now putting the value of x from the second equation to the first , we get
x + y = 15/4
2y + (3/2) + y = 15/4
3y = (15/4) - (3/2)
3y = (15 - 6)/4
3y * 4 = 9
12y = 9
y = 9/12
= 3/4
Now putting the value of y in the first equation, we get
x + y = 15/4
x + (3/4) = (15/4)
x = (15/4) - (3/4)
= (15 - 3)/4
= 12/4
= 3
So the value of x or the larger number is 3 and the value of y or the smaller number is 3/4.
