Answer: Approximately 79 Percent
Step-by-step explanation:
The confidence level used in this estimation is approximately 79 percent.
The probability is found from a suitable table or probability calculator.
p(z < 1.3) ≈ 0.9031995154
<u>Answer</u>
26.6°
<u>Explanation</u>
You are required to use the trigonometric ratio, sine, to find that angle.
SinФ = opposite/hypotenuse
sin Θ = 2.6/5.8
= 0.4483
The angle Θ = Anti-sine(0.4483)
= 26.633°
The angle the slide makes with the ground, correct to one decimal place is 26.6°
We convert degrees to radian by multiplying by (
)
= (345) × (
)
= (
) × (π)
= 1.9166π
= 1.9166 × 3.14
= 6.018 rad
≈ 6.02 rad
