B. The numbers 22% and 17% represents the sample statistics
Step-by-step explanation:
The study was based on a recent research that suggest that depression significantly increases risk of dementia later in life, so for every result gotten from this study, it is tied to only the samples chosen for the aim of the study which are the 949 elderly people.

Step-by-step explanation:
Look at the given angles and see what they are: interior, exterior, alternate, same side, etc.
If the lines are given as parallel, use the theorem.
If you show the lines are parallel, use the converse.

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Initially, Greg has a total of 60 DVDs and CDs in his collection.
He then sold 1/8 of his CDs and 1/2 of his DVDs.
Let the number of CD is c and DVD is d
c + d = 60
2(c/8) = d/2
d = 60 - c
4(2c/8) = 4(60-c)/2
c = 120 - 2c
c = 40
d = 60-40 = 20
Thus, Greg has 40 CD's and 20 DVD's. He sold 10 DVDs and 1/8 of his CD(40/8 = 5).

Answer:
10 DVD's were sold.
Step-by-step explanation:
c = number of CD's
d = number of DVD's
so we know:
c + d = 60
2*c/8 = d/2
this can be solved:
d = 60 - c
2c / 8 = (60-c)/2
4*(2c/8) = 4*(60-c)/2 [multiply by 4]
c = 120 - 2c
3c = 120
c = 40
d = 60-40 = 20
So Greg had 40 CD's and 20 DVD's. He sold half of his DVD's, i.e., 20/2=10 and 1/8 of his CD, i.e., 40/8 = 5
