Raigan as a 45.82.so she gets a 100 .then the next day she gets a 100 points .what is her grade

Raigan has a grade of %81.94

Step-by-step explanation:

Step 1:  Add the numbers together

45.82 + 100 + 100

245.82

Step 2:  Find the amount of numbers

45.82, 100, 100

   1        2      3

There are 3 numbers

Step 3:  Find the average

Sum of numbers / Total amount of numbers

245.82 / 3

%81.94

 Raigan has a grade of %81.94

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
