PLEASE HELP URGENT On a scale model of a building, 1/4 inch represents 3/8 foot.

Fudgin [204]

Answer:

Step-by-step explanation:

1/4 inch to 3/8 ft = x inches to 1 ft

(1/4) / (3/8) = x / 1

cross multiply because this is a proportion

3/8x = 1/4

x = 1/4 * 8/3

x = 8/12 which reduces to 2/3 inches <==

The Atlanta Journal Constitution conducted a survey of 900 registered voters to determine which voting method they prefer. The A

photoshop1234 [79]

Answer:

a) (0.576, 0.624)

Step-by-step explanation:

Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%

α = 1 - C = 1 - 0.85 = 0.15

α/2 = 0.075

The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence $z_\frac{\alpha }{2} =1.44$

The margin of error (E) is:

$E=z_\frac{\alpha }{2} *\sqrt{\frac{p(1-p)}{n} } =1.44*\sqrt{\frac{0.6(1-0.6)}{900} } = 0.024$

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
