To test the effect of living environment on cholesterol levels using samples from rural and urban areas, the best statistical test to utilize would be the two-sample t-test.
The two-sample t-test is appropriate in this case because it compares the means of two independent groups (rural and urban residents) to determine if there is a significant difference between their cholesterol levels.
This test will help researchers determine if living environment has an impact on cholesterol levels.

1c Alternate interior angles converse theorem
1d Corresponding angles theorem
1e Same-side interior angles theorem
1f Same-side exterior angles theorem
1g Same-side interior angles converse theorem
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.

Line CD passes through points C(3, 5) and D(6, 0). What is the equation of line CD in standard form?
5x + 3y = 18
O 5x - 3y = 30
O 5x2y = 30
O 5x + y = 18

Answer:
5x + 3y = 15
Step-by-step explanation:
As Line CD passes through points C(3, 5) and D(6, 0), x (the "run") increases by 3 and y (the "rise") decreases by 5. Thus, the slope of line CD is
m = rise / run = -5/3, and in slope-intercept form the following is true:
y = mx + b => 5 = (-5/3)(3) + b, or b = 5.
Then the equation of the line is y = (-5/3)x + 5. Converting this to standard form, we get:
3y = -5x + 15, or 5x + 3y = 15
