A spinner has five equal parts labeled from 1 to 5. The spinner is spun twice. what is the probability of getting 4 twice in a row?

1/25

Step-by-step explanation:

Since there are 5 parts, and one is the number 4, the chance of getting 4 is 1/5.

To find the probability of getting 4 twice in a row, multiply 1/5 by itself again, since it will happen twice:

1/5 x 1/5

= 1/25

So, the probability is 1/25

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
