Answer:

I believe the answer is 43.25

Step-by-step explanation:

The sum of all of the angles has to equal 180 degrees. The degree 93.5 is already known so you can subtract that from 180. We have 86.5 left, which is the sum of the two angles that we don’t know yet. I am assuming that they are equal, so you can divide 86.5 by two and get 43.25. I believe this is your answer.

Answer:

$\huge\boxed{A.\ -\dfrac{9}{4}+2i}$

Step-by-step explanation:

The standard form of a complex number:

$z=a+bi\\\\a,\ b\in\mathbb{R}$

$3i+\left(\dfrac{3}{4}+2i\right)-(3+3i)=3i+\dfrac{3}{4}+2i-3-3i\\\\=\left(\dfrac{3}{4}-3\right)+(3+2-3)i=-2\dfrac{1}{4}+2i=-\dfrac{9}{4}+2i$

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:

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