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.
Answer:
-6 and -2
Step-by-step explanation:
Answer:
10.4
Step-by-step explanation:
(10x - 4)/5 = 20
(10x - 4) = 20 * 5
10x - 4 = 100
10x = 104
x = 104/10
x = 10.4
I would appreciate brainliest, have an amazing day!
Volume of a cone = (PI * radius^2 * height) / 3
Volume of a cone = (PI * 3^2 * 8) / 3
Volume of a cone = (PI * 24)
Cylinder Volume = PI • r² • height
Cylinder Volume = PI * 3^3 * 12
Cylinder Volume = PI * 108
TOTAL Volume = PI * 132
Answer:
5 days
Step-by-step explanation:
This would have to do with average. So if one does it in 6 days and the other does it in 4 days, you would do the number between them. So 5 is between 4 and 6.
The more complicated way of thinking of it is like this...
add 6 and 4 6+4 that would = 10
Because we added two numbers, we have to divide by two.
10/2 which equals 5.
If it was numbers closer together like. 6 and 7 the middle numbeR would be 6.5 for example.
I hope this helped!!
