Semicircle perimiter=1/2circumferece+diameteter
diameter=2r
c=2pir
so 1/2circumference=1/2(2pir)=pir
d/2=r

given
d=30
d/2=30/2=15=r

perimiter=pir+d
perimiter=15pi+30
aprox
perimiter=77.1239

A consumer group surveyed 146 airplane travelers after a flight and found that 132 of them would fly that airline again. Find th

prohojiy [21]

Answer:

$\hat p =\frac{X}{n}$

And replacing we got:

$\hat p =\frac{132}{146}= 0.904$

And for this case the standard error assuming normality would be given by:

$SE= \sqrt{\frac{\hat p (1-\hat p)}{n}}$

And replacing we got:

$SE= \sqrt{\frac{0.904*(1-0.904)}{146}}= 0.024$

Step-by-step explanation:

For this problem we know the following notation:

$n= 146$ represent the sample size selected

$X= 132$ represent the number of airplane travelers who after a flight would fly that airline again

The estimated proportion for this case would be:

$\hat p =\frac{X}{n}$

And replacing we got:

$\hat p =\frac{132}{146}= 0.904$

And for this case the standard error assuming normality would be given by:

$SE= \sqrt{\frac{\hat p (1-\hat p)}{n}}$

And replacing we got:

$SE= \sqrt{\frac{0.904*(1-0.904)}{146}}= 0.024$
