Answer:

(0.1392,0.1466)

Step-by-step explanation:

Given that a survey given to consumers leaving a supermarket three days before Thanksgiving asked whether turkey would be part of the Thanksgiving meal

People surveyed = 182

claimed not eating turkey = 26

Sample proportion = $\frac{26}{182} \\=0.1429$

Std error = $\sqrt{\frac{pq}{n} } \\=0.0260$

Margin of error = 1.96*SE= $0.00378$

Confidence interval = $(0.1429-0.0037,0.1429+0.0037)\\=(0.1392,0.1466)$

What are the solutions of the equation?

andre [41]

Answer:

Step-by-step explanation:

0 = x2 + 3x - 10

10 = 2x+3x

10 = 5x

x = 2

0x = 5.2

0x = 10

x = 10.2 = 20

x = 20

0x = -5.-2

0x = -10

x = -10.2 = -20

x = -20

x = -5.2

x = -10

x = 5-2

x = 3

GOOD LUCK ! ;)
