oksian1 [2.3K]

Answer:

80

Step-by-step explanation

Write down the equation: (15 / 100) * x = 12

Solve for x: x = 12 / (15 / 100)

x = (12 * 100) / 15

or, x = 80

   Hope this helps!

If f(x)=3x+2,find f(f^-1(14)).
lisov135 [29]

Answer:  14

<u>Step-by-step explanation:</u>

f(x) = 3x + 2

To find f⁻¹, swap the x's and y's and solve for y --> Note: f(x) is y

x = 3y + 2

x - 2 = 3y

\dfrac{x-2}{3}=y

\implies f^{-1}(x)=\dfrac{x-2}{3}

\implies f^{-1}(14)=\dfrac{14-2}{3}

\implies f^{-1}(14)=\dfrac{12}{3}

\implies f^{-1}(14)=4

f(f⁻¹(14)) = f(4)

              f(4) = 3(4) + 2

                     = 12 + 2

                     = 14

NOTE: the simplified version is .... f and f⁻¹ cancel out, leaving you with 14

Please reference attached image for the problem that requires solving. Thank you so much for taking the time to help.
Lemur [1.5K]

Explanation:

The number of times the 6-sided number cube will be rolled will is

750

Let the numbers greater than 4 be represented below as

E_1\begin{gathered} E_1=\lbrace5,6\rbrace \\ n(E_1)=2 \end{gathered}

The number of sample space will be

n(S)=6

The probability of rolling a number greater than 4 will be calculated below as

\begin{gathered} Pr(E_1)=\frac{n(E_1)}{n(S)} \\ Pr(E_1)=\frac{2}{6}=\frac{1}{3} \end{gathered}

Hence,

To calculate the number of times a number greater than 4 will be rolled will be calculated below as

\begin{gathered} =Pr(E_1)\times750 \\ =\frac{1}{3}\times750 \\ =250times \end{gathered}

Hence,

The final answer is

\Rightarrow250\text{ }times
