Each letter of the word "thunderstorm" has been written on a separate slip of paper and put into a box. Find the probability of

xxTIMURxx [149]

SOLUTION

From the question, we want to find the probability of selecting a slip of paper with the letter t on it, then selecting the letter r, with replacement.

This means the probability of selecting t and r.

That is

$P(t)\times P(r)$

There are 12 letters (total outcomes). And there are 2r and 2t.

So probability becomes

$\begin{gathered} \frac{possible\text{ outcome}}{\text{total outcome }} \\ P(t)=\frac{2}{12} \\ P(r)=\frac{2}{12} \\ P(t)\times P(r)=\frac{2}{12}\times\frac{2}{12} \\ =\frac{1}{6}\times\frac{1}{6} \\ =\frac{1}{36} \end{gathered}$

Hence the answer is

$\frac{1}{36}$

Find the value of x.

Trava [24]

Answer:

x = 53

Step-by-step explanation:

The sum of the exterior angles of a convex polygon is always 360°.

x +x +59 +48 +50 +39 +58 = 360

2x +254 = 360 . . . . simplify

x +127 = 180 . . . . . . divide by 2

x = 53 . . . . . . . . . . . subtract 127

ella [17]

Answer:

$P(x)=-2x^2+28x-66$

Step-by-step explanation:

$P(x)=-2(x-3)(x-11)\\\\P(x)=-2(x^2-3x-11x+33)\ \ \ \ \ \ multiplication\ of\ (x-3)\ and\ (x-11)\\\\P(x)=-2(x^2-14x+33)\ \ \ \ \ \ \ distributive\ property\\\\P(x)=-2x^2+28x-66$
