Step-by-step explanation:
csc x / (cot x + tan x)
Write in terms of sine and cosine.
(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]
Multiply top and bottom by sin x.
1 / [cos x + (sin²x / cos x)]
Multiply top and bottom by cos x.
cos x / (cos²x + sin²x)
Use Pythagorean identity.
cos x / 1
cos x
<span>x + 9 = 2(x - 1)^2
x + 9 = 2(x^2 - 2x + 1)
x + 9 = 2x^2 - 4x + 2
</span>2x^2 - 4x + 2 - x - 9 = 0
2x^2 - 5x -7 =0

Answer:
Step-by-step explanation:
<u>Given</u>
- Total applicants = 431
- Applicants with graduate degree and over 5 years of experience = 103
Probability = favorable outcomes/total outcomes
<u>Required probability </u>
- 103/431 = 0.2390 rounded to 4 decimal places
