Which equation is correct
Sergeeva-Olga [200]
1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).


 Sin x°=Opposite/Hypotenuse

 Cos x°=Adjacent/Hypotenuse

 2. The inverse of Sinx° is Cosec x°, then:

 Cosec x°=1/Sin x°

 3. The inverse of Cos x° is Sec x°, then:

 Sec x°=1/Cos x°

 4. Keeping this on mind, you have:

 Cosc x°=Hypotenuse/Opposite

 Sec x°=Hypotenuse/Adjacent

 5. Therefore, the correct answer is:

 The third option: Cosec x°=Hypotenuse/Opposite.

A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 1
Harman [31]

The probability that the mean clock life would differ from the population mean by greater than 12.5 years is 98.30%.

Given mean of 14 years, variance of 25 and sample size is 50.

We have to calculate the probability that the mean clock life would differ from the population mean by greater than 1.5 years.

μ=14,

σ=\sqrt{25}=5

n=50

s orσ =5/\sqrt{50}=0.7071.

This is 1 subtracted by the  p value of z when X=12.5.

So,

z=X-μ/σ

=12.5-14/0.7071

=-2.12

P value=0.0170

1-0.0170=0.9830

=98.30%

Hence the probability that the mean clock life would differ from the population mean by greater than 1.5 years is 98.30%.
