What is the exterior and interior angle of a 18 sided polygon
GREYUIT [131]
Would assume the Polygon is an 18 sided regular polygon.

Exterior angle for regular polygon = 360/n      (Sum of angles of exterior angles = 360°)

where n = number of sides.

Exterior angle = 360 / 18 = 20

Exterior angle = 20°

Sum of exterior angle + Interior angle = 180°    (Both angles are on a straight line, so the sum is 180°)

Interior angle = 180° - 20°

Interior angle = <span>160°

</span>Hope this explains it.

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)
