Answer:
Here the sample is the college students, and the researcher want's to do a survey to obtain information about marriage patterns.
Then, the ideal sample will be constituted of students of both genders, of different ideologies, of different social classes, of different religions, etc.
Then the thing that the researcher needs to do is:
Define the size of the sample
Assign to each student a unique number.
using a random number generator, generate enough different numbers to fill the sample.
Each of these numbers corresponds to a unique student, so now you have a complete sample of random selected students.
This sample can not be biased in any way.
It would be 100,300
Hope this helped
Answer:

Step-by-step explanation:
Since the divisor of
is in the form of
use what is called Synthetic Division. Remember, in this formula, −c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
−1| 2 1 0 1
↓ −2 1 −1
__________
2 −1 1 0 → 
You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [2x³ + x² + 1]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than the leading coefficient of your dividend, so that 2 in your quotient can be a 2x², the −x follows right behind it, and bringing up the rear, 1, giving you the quotient of 2x² - x + 1.
