International data show a positive correlation between income per person and the health of the population. Which of the following scenarios supports this finding and accurately describes how health outcomes relate to productivity?(A) Individuals with higher incomes have better access to clean water, medical care, and good nutrition, and healthier individuals are likely to be more productive than sick ones.(B) Individuals with lower incomes are in better health thanks to cheaper medical alternatives such as home remedies, and healthier individuals are likely to be more productive than sick ones.(C) Individuals with lower incomes are in worse health, but this leads to greater productivity because sicker workers have higher medical expenses.

Individuals with higher incomes have better access to clean water, medical care, and good nutrition, and healthier individuals are likely to be more productive than sick ones.

Correlation refers to the relationship or association that exists between two variables taken into account for the research. There are three types of correlation such as positive, negative and no relation. Positive correlation refers to the situation when one variable is changed the other one will also be changed at the similar rate.

In the given scenario, it is said that there exists a positive correlation between the income per person and the population health. This means that when the individuals receives higher income then they can afford for getting clean water, medical care and also good nutrition and hence the healthier individuals will be more productive than the sick ones. This is because they can go for work without any leave or absence.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
