Answer:

I believe these would be considered elliptical galaxies. These are the direct result of two or more stars or galaxies that collide with each other.

Explanation:

I took Astronomy a while back.

Giant elliptical galaxies
This is why giant elliptical galaxies, the results of galaxy collisions, have so many old red stars and very little active star formation. Images from Hubble's ACS in 2004 and 2005 show four examples of interacting galaxies (at various stages in the process) far away from Earth.

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%.
