4. sherman hopes to get at least a 90 average on his science tests. he has one more test

before the end of the school year. his past test scores are 79, 94, 91, and 92. write and

solve an inequality that represents this situation. what is the lowest score sherman can

get on his final test and reach his goal? show your work.

оно

79+94+91+92+test5)/5=90

The lowest score have to be 94

Step-by-step explanation:

Our goal is gona be to have an average of 90, it can be higher but we are going to use this.

For average the equation is

(test1+test2+test3+test4+test5)/5=average

We know the result for the first 4 tests

Test 1=79

Test 2=94

Test 3=91

Test 4=92

But we dont know test 5

(79+94+91+92+test5)/5=average

Our goal for the average is 90

(79+94+91+92+test5)/5=90

79+94+91+92+test5=90*5

test5=450-79-94-91-92

Test5=94

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 !
