Answer:
The answer to your question is the third choice secФ = 41/40
Step-by-step explanation:
Data
Opposite side = 9
Adjacent side = 40
hypotenuse = 41
Process
To solve this problem use trigonometric functions. The secant is the trigonometric function that relates the hypotenuse and the adjacent side.
sec Ф = hypotenuse / adjacent side
hypotenuse = 41
adjacent side = 40
then,
secФ = 41/40
Answer:
0.101
Step-by-step explanation:
Given that :
Standard deviation, s = 0.2
Sample variance, s² = 0.0653
Sample size, n = 10
Population variance = σ² = 0.04
We use the Chi square distribution :
(n - 1)s² / σ²
For P(s² ≥ 0.065)
(n - 1)s² / σ² = (10 - 1)*0.0653 / 0.04
(n - 1)s² / σ² = 0.585 / 0.04 = 14.625
P(s² ≥ 14.625) = 0.101 ( chi squee calculator).
