Answer:

Intervalo de confianza

= (0.294, 0.386)

Step-by-step explanation:

La fórmula para el intervalo de confianza para la proporción se da como

p ± z × √p (1 - p) / n

Donde p = x / n

De donde de la pregunta anterior

x = 136 personas

n = 400 personas

p = 136/400

p = 0.34

z = puntuación z del intervalo de confianza del 95% = 1.96

Por lo tanto,

Intervalo de confianza =

0.34 ± 1.96 × √0.34 (1 - 0.34) / 400

= 0.34 ± 1.96 × √0.34 × 0.66/400

= 0.34 ± 1.96 × √0.000561

= 0.34 ± 1.96 × 0.0236854386

= 0.34 ± 0.0464234596

Intervalo de confianza

= 0.34 - 0.0464234596

= 0.2935765404

= 0.34 + 0.0464234596

= 0.3864234596

Hence:Intervalo de confianza

= (0.294, 0.386)

Factor this problem ?<br> 125 +27y^3
koban [17]

Answer:

(5 + 3y)(25 - 15y + 9y²)

Step-by-step explanation:

This is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²), thus

125 + 27y³

= 5³ + (3y)³ with a = 5 and b = 3y

= (5 + 3y)(5² - 5(3y) + (3y)² )

= (5 + 3y)(25 - 15y + 9y²)
