There are 12 chocolate in a box,3 white,4 milk and the rest dark chocolates. What is the probability that Lily first chooses a dark chocolate from the box

5/12

Step-by-step explanation:

Total chocolate=12

White=3

Milk=4

Dark=x

White+milk+dark=3+4+x

=7+x

12=7+x

x=12-7

x=5

Therefore,

Dark=5

Probability that Lily first chooses a dark chocolate from the box= No. Of dark chocolate/Total no. Of chocolate

=5/12

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
