Answer:

A

Step-by-step explanation:

this is a standard right triangle 30-60-90

with legs 1 and \sqrt{3} and hypotenuse 2, hence

s = \sqrt{3} and h = 2

Answer:

A. \sqrt{3} ; 2

Step-by-step explanation:

Since We have all the angles of the triangle and one side we can use SIN, COS, and TAN to find the missing side lengths. SIN which is sin(x) = \frac{opposite}{hypotenuse} can be used to find the hypotenuse

sin(30) = \frac{1}{h}

\frac{1}{sin(30)} = \frac{h}{1} ..... inverse both sides

\frac{1}{sin(30)} = h

2 = h

Now we can use the Pythagorean theorem to find the missing length. The Pythagorean Theorem is a^{2} +s^{2} = h^{2}. So we just plug in the values we already have and solve for s.

1^{2} +x^{2} = 2^{2}

1+s^{2} = 4

s^{2} = 3

s = \sqrt{3}

In Conclusion, s = \sqrt{3} and h = 2

In a random sample of 300 attendees of a minor league baseball game, 182 said that they bought food from the concession stand. C
horrorfan [7]

Answer:

<em>90% confidence interval for the proportion of fans who bought food from the concession stand</em>

(0.5603,0.6529)

Step-by-step explanation:

<em>Step(i)</em>:-

<em>Given sample size 'n' =300</em>

Given data  random sample of 300 attendees of a minor league baseball game, 182 said that they bought food from the concession stand.

<em>Given sample proportion </em>

<em>                        </em>p^{-}  = \frac{x}{n} = \frac{182}{300} =0.606

level of significance = 90% or 0.10

Z₀.₁₀ = 1.645

<em>90% confidence interval for the proportion is determined by</em>

(p^{-} - Z_{0.10}\sqrt{\frac{p(1-p)}{n} }  , p^{-} +Z_{0.10}\sqrt{\frac{p(1-p)}{n} })

(0.6066 - 1.645\sqrt{\frac{0.6066(1-0.6066)}{300} }  ,0.6066+1.645\sqrt{\frac{0.6066(1-0.6066)}{300} })

(0.6066 -  0.0463  ,0.6066 +  0.0463)

(0.5603,0.6529)

<u>final answer</u>:-

<em>90% confidence interval for the proportion of fans who bought food from the concession stand</em>

(0.5603,0.6529)
