Answer:

If this is a 6 sided fair die, P = 1/3

Step-by-step explanation:

Fair means you have an equal chance of getting each option. P(3 and 4) = P(3) + P(4) = 1/6 + 1/6 = 2/6 = 1/3.

What are the solutions to the quadratic equation (5y+6)2=24
yulyashka [42]

The value of y is, y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}

We have given that,

\left(5y+6\right)^2=24

We have to determine the value of y,

<h3>What is the formula for the quadratic equation?</h3>

\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

Therefore,we get

5y+6=\sqrt{24}

5y+6=2\sqrt{6}

\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}

5y+6-6=2\sqrt{6}-6

5y=2\sqrt{6}-6

\frac{5y}{5}=\frac{2\sqrt{6}}{5}-\frac{6}{5}

y=\frac{2\sqrt{6}-6}{5}

y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}

Therefore the value of y is,

y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}
