Answer:

Step-by-step explanation:

The formula for determining the the volume of a rectangular base pyramid is expressed as

Volume = 1/3 × base area × height

From the information given,

Length of base = 9 cm

Width of base = 4.6 cm

Area of base = 9 × 4.6 = 41.4 cm²

Volume of pyramid = 82.8cm³

Therefore

82.8 = 1/3 × 41.4 × height

82.8 = 13.8 × height

Dividing both sides of the equation by 13.8, it becomes

height = 82/13.8

Height = 5.94 8 cm

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)
