325 people were in a tour group six buses were completely filled and 7 people choose to walk how many people did the bus hold?

Well when you think about this, if 7 people are walking, you can automatically take them out of the total. So you have 318 people who are taking busses. Now take that 318 and divide it among 7 busses. So 318/7 = 45.4285714286. Now looking at this, logically you can't put half a person on one bus and half a person on another, you can't have 1/4 of a person on your bus. So this means some busses would carry 1 more than others. So logically each bus would have to be able to hold 46 people.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

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 !
