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

2x-4<br> 30<br> 15x - 30<br> PAP

Alex787 [66]

Answer:

$\frac{2}{25}$

Step-by-step explanation:

Given expression,

$\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }$

=> $\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }$

We see that $(x-2)$ is common in both numerator and denominator

hence canceling out we get:-

$\frac{2*18}{30*15}=\frac{2}{25}$

Answer= $\frac{2}{25}$
