Mouthwash company advertises that 90% of dentists recommend their product a random number generator is used to stimulate the results of asking the next for dentist the numbers zero through eight represents the dentist who recommended the mouthwash in the number nine represent dentist who do not what is the probability that exactly 2 of the three dentist ask would recommend the mouthwash

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
