The probability that the next person will be assigned an orchestra seats is 2/5.

<h3>What is Probability?</h3>

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Available Orchestra seats = 8

            Balcony seats = 12

      Total available seats = 12 + 8 = 20

  Probability = Favorable Outcome / Total Outcome

  Probability of getting orchestra ticket = 8/20

                                                                 = 2/5

Thus, the probability that the next person will be assigned an orchestra seats is 2/5.

The length of segment XY is 9 cm. Which statements regarding triangle XYZ are correct? Check all that apply.
Dominik [7]

<u>Answer-</u>

  • YZ = 9 cm
  • XZ=9\sqrt2
  • XZ is the longest segment in triangle XYZ.

<u>Solution-</u>

Triangle XYZ is a right angle triangle with ∠Y=90°

Triangle XYZ is also an isosceles triangle, as

∠X =45°= ∠Z

Therefore, triangle XYZ is a right angle isosceles triangle.

So,

XY = YZ = 9 cm

Applying Pythagoras theorem,

\Rightarrow XZ^2=XY^2+YZ^2\\\\\Rightarrow XZ^2=9^2+9^2\\\\\Rightarrow XZ^2=2\times 9^2\\\\\Rightarrow XZ=\sqrt{2\times 9^2}=9\sqrt2

In a right angle triangle, always the hypotenuse is the largest. So XZ is the longest segment in triangle XYZ.

If s(x) = 2 - x and f(x) = 3x, which value is equivalent to (s f) (-7)
Soloha48 [4]

Answer:

Step-by-step explanation:

the first method :

s(x) = 2 - x and f(x) = 3x

(s f) (-7) = s(-7) ×f(-7)

but : s(-7) = 2 - (-7) =2+7 = 9

       f(-7) = 3(-7) = - 21

so : (s f) (-7) = (9)×(-21) = - 189

the second method :

calculate : (s f) (x) == s(x)×f(x) = (2-x) 3x = 6x - 3x²

(s f) (-7) = 6(-7) -3 (-7)² = - 42 -147 = -189
