During a physical exercise drill, athletes have to run to the first marked line then back to the starting point. They then turn around and run to the next marked line and then back again to the starting point. This repeats until the athlete reaches the final marked line. The distance in feet run for each line can be represented by the function D(l)=2(20l) where l is the number of lines the athlete ran to and from. How many feet would an athlete have run in total if he had just finished running to and from the 10th line? : feet

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

i those same problems in math and dont know how to do them

answer: graphs are something you write or draw and equations are math problems
