Answer:

x = 0.6623

y = 8

Image is attached for refernce of my solution

Step-by-step explanation:

In Δ DEF

By applying pythagoras theoram,

DE = \sqrt{EF^{2} - DF^{2}  }

     =\sqrt{17^{2} - 15^{2}  }  = \sqrt{289 - 225}  = \sqrt{64}  =8

∴ DE = 8

In Δ ABC

BC = y = 12 sin 30° = 6

AC = \sqrt{3} + DE + x = \sqrt{3} + 8 + x = 12 cos 30°

⇒ 9.73 + x = 10.39

<h3>⇒ x = 0.6623</h3>

Rzqust [24]

Correct Question:

He counts 18 female students, 16 male students, and 6 teachers. There are

720 people in the auditorium. Consider the probability of selecting one person

at random from the auditorium.

Which of these statements are true?

Choose all that apply.

A:  The probability of selecting a teacher is 6%.

B : The probability of selecting a student is 85%.

C : The probability of selecting a male student is 32%.

D : The probability of selecting a female student is 45%.

Step-by-step explanation:

Option B  and D are correct because

The total number of people in one cross section = 18 + 16 + 6 = 40.

A = The probability of selecting a teacher is = (6/40)x100 = 15 % not equal to 6 %

B = The probability of selecting a male student is = (34/40)x100 = 85%

C = The probability of selecting a male student is = (16/40)x100 = 40 % not equal to 32 %

D : The probability of selecting a female student is = (18/40)x100= 45%
