Answer:
The targeted population is USA residents who died of heart disease.
Step-by-step explanation:
According to this case, "the death rates due to heart disease among the smokers and nonsmokers are compared to see if smoking causes heart disease." This implies that the study targets those USA residents who died of heart disease to find out if the cause of death can be traced to heart disease caused by smoking or not. The main concentration for the study defines the targeted population. It is this group of residents who died of heart disease that is the population of interest. This means that the targeted population is a certain group of the population that share similar characteristics, especially death resulting from heart disease caused by smoking.
Answer:
Step-by-step explanation:
In the question, we're given 
. Therefore, the measure of these two angles must be equal.
To find the value of 
, set these two angles equal to each other:
Add 26 and subtract from both sides:
Divide both sides by 3:
Since 
was labelled as 
, substitute 
to find its measure:
You can also substitute into the label of angle D as angle A is congruent to angle D for easier calculations (
).
Answer:
7.1
Step-by-step explanation:
write pythagorean theorem 
+ = 
2
= 100
divide 2 both side:
= 50
= 
=
= 7.07106781
round to nearest tenth:
= 7.1
You basically multiply the number outside the parentheses by everything inside.
So 2 × 6x = 12x,
2 × 5 = 10,
2 × 2y = 4y.
So your answer is 2(6x + 5 + 2y).
