Hostility is related to coronary heart disease and may contribute to premature death.
erik [133]

Answer:

True

Explanation:

Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.

Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients  to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and  blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart.  It is said that some slight modifications to care for coronary heart disease  include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.

Hostility levels is also related as  a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.

For a particular species of wolf, 55% are female, 20% hunt in medium-sized packs, and 15% are both female and hunt in medium-siz
lorasvet [3.4K]
*Given
Percent of the wolves which are female - 55%
Percent of the wolves which hunt 
     in medium-sized packs                      - 20%
Percent of the wolves which are both
     female and hunt in medium-sized
     packs                                                  - 15%


*Solution

<u>Assuming that there is a total of one hundred wolves in the species, </u>

1. Since percent (%) means "per 100" or "for every 100" then, 

a. The number of female wolves is

    (55 female wolves / 100 wolves) * 100 wolves total = 55 female wolves

b. The number of wolves that hunt in medium-sized packs is

    (20 wolves / 100 wolves) * 100 wolves total = 20 wolves

    Note that the 20 wolves is a mixture of male and female wolves. 

c. The number of female wolves that hunt in medium-sized packs is

    (15 female wolves / 100 wolves) * 100 wolves total = 15 female wolves

2. Because there is a total of 55 female wolves in the species, and 15 of these wolves hunt in medium-sized packs, then the number of female wolves that do not hunt in medium-sized packs is, 
 
    55 female wolves total - 15 female wolves hunting  = 40 female wolves not
                                                in medium-sized packs         hunting in medium
                                                                                              sized packs

3. To find the proportion, we can express the answer in terms of percent (%) or in fraction, which is usually how proportions are expressed. 

For every 100 wolves, there are 40 female wolves that do not hunt in medium-sized packs. This can be expressed as a proportion of 
 
                                       <span> <u> 40  </u>
</span>                                        100

and simplified by dividing both the numerator and denominator by 10, we get,

                                     <span><u> 40/10  </u>
</span>                                     100/10

                                       <span><u>  4   </u>
</span>                                        10

When this is expressed in percent, we multiply the fraction or proportion by 100% to get, 

                                       <span><u>  4   </u>   x    100%     = 40%
</span>                                        10

Thus, the proportion of female wolves that do not hunt in medium sized packs is 4/10 or 0.4. When expressed as percent, this is 40%.
