Chance rolls a 1-6 number cube. What is the probabilty that he will roll a prime number

B

Step-by-step explanation:

There are six numbers altogether. 2 3 and 5 are prime. One is odd, but it is not considered prime.

So P(prime) = 3/6 = 1/2

As a percent, this is 1/2 * 100 = 50%

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

what grade level is this? need to know so i can look in my old textbooks!
