3. the grade a student earns on a test varies directly with the amount of time the student spends studying. suppose a student spends 5.5 hours studying and makes a grade of 76% on the test. what is an equation that relates the grade earned on a test, g, with the amount of time spent studying, t, in hours? what is the garish of your equation.

The required equation is .

Step-by-step explanation:

Consider the provided information.

It is given that The grade a student earns on a test varies directly with the amount of time the student spends studying.

First find the slope of the line using the formula:

Since the grade rise to 76 after spending 5.5 hours studying.

Thus, the slope of the line is:

It is given that equation varies directly with the amount of time the student spends studying.

Thus the equation should be in form of

where k is a constant.

Substitute b=g, a=t and k=13.8182 in .

Hence, the required equation is .

Check: Substitute t=5.5 in

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

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 !
