5 cm = 2km

Scale= 5 cm : 200000 cm

= 1 : 40000

a. 1 : 40000 = x : 500000

x = 12.5 cm

b.1 : 40000 = 2 : x

x = 80000 cm

x = 0.8 km

A questionnaire was sent to 34,000 randomly chosen individuals living in USA asking about their current and past smoking habits.
kherson [118]

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.

Help please! Identify an equation in point slope form for the line perpendicular to Y =-1/2x+11that passes through (4,-8)
juin [17]

Answer:

y=2x+8

Step-by-step explanation:

You set the slope to the opposite of -1/2 which is 2/1 or 2.

Then you do b=2(4) (because 4 is the x in the coordinate points)

and solve for b you get 8 so

Y=2x+8
