Theoretical Probability - Guided Practice#1 - All of the letters in the word Mississippi are written on separate pieces of paper
Naily [24]

The probability = outcome/total outcomes

The total of the outcomes is the total number of the letters of the given word, then

The total outcomes = 11

The outcome is the number of letter "s" in the word

The outcome = 4, then

The probability of "s" is

P(s)=\frac{4}{11}

To change it to percent multiply it by 100% and round it to the nearest 1 decimal place

\begin{gathered} P(s)=\frac{4}{11}\times100 \\ P(s)=36.4 \end{gathered}

The answer is 36.4%

Which of the following is not a solution to the equation −2x + 3y = 9.
lakkis [162]

Given that the equation -2x+3y=9

We need to determine the coordinate that is not a solution to the equation.

<u>Option A</u>: (0,3)

Substituting the coordinate (0,3) in the equation -2x+3y=9, we get;

-2(0)+3(3)=9

           0+9=9

                 9=9

Since, both sides of the equation are equal, then the coordinate (0,3) is a solution to the equation.

Hence, Option A is not the correct answer.

<u>Option B</u>: (1,-3)

Substituting the coordinate (1,-3) in the equation  -2x+3y=9, we get;

-2(1)+3(-3)=9

           -2-9=9

               -11\neq 9

Since, both sides of the equation are not equal, then the coordinate (1,-3) is not a solution to the equation.

Hence, Option B is the correct answer.

<u>Option C</u>: (-3,1)

Substituting the coordinate (-3,1) in the equation  -2x+3y=9, we get;

-2(-3)+3(1)=9

              6+3=9

                    9=9

Since, both sides of the equation are equal, then the coordinate (-3,1) is a solution to the equation.

Hence, Option C is the correct answer.

Therefore, the coordinate (1,-3) is not a solution to the equation -2x+3y=9
