Answer:
The sample size 'n' = 72,030
Step-by-step explanation:
<u>Step(i):-</u>
<em>Given that the Estimate Error = 0.013</em>
<em>Given that the standard deviation of the Population = 1.5</em>
<em>The estimated error is determined by </em>
<em />
<em />
<u><em>Step(ii):-</em></u>
<em>Given that the Level of significance = 0.98 or 0.02</em>
<em>Z₀.₀₂ = 2.326</em>
<em>The estimated error is determined by </em>
<em> </em>
<em />
<em> </em>
<em />
<em> </em>
<em />
<u><em>Squaring on both sides, we get</em></u>
<em> n = 72,030</em>
<u><em>Final answer:-</em></u>
The sample size 'n' = 72,030
Answer:
cosθ = -√(35/36)
tanθ = -1/√35
Step-by-step explanation:
We know that
sin²θ + cos²θ = 1
(1/6)² + cos²θ = 1
1 - (1/6)² = cos²θ
35/36 = cos²θ
sec θ = 1/ cosθ
1/ secθ = cos θ
Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0
cosθ = -√(35/36)
tanθ = sinθ/cosθ = (1/6)/-√(35/36)
= (1/6) / -(√35/6)
= -1/√35
