<h2>Answer: </h2>

1. Defined as bounded by two distinct end points that contain every point on the line between its end points.

B) line segment

A line segment is shown by end points on each end of the line segment and is represented by a line with arrows at each end.

2. If you rotate a right triangle, what feature of the triangle changes?

D) position of the triangle

When we rotate any figure, the angles and sides remain the same measure. The only thing that changes is its position.

3. Which transformation will be equivalent to rotating a figure 180° counterclockwise?

C) reflecting over the x-axis and the y-axis.  

When we rotate a figure counterclockwise 180° , the coordinates change from (x, y) to (-x, -y).  

Moving forward, when that figure is reflected over the x axis the coordinates change from (x, y) to (x, -y).  

Again reflecting it over the y-axis the coordinates change from (x, -y) to (-x,-y).  

Therefore, we can say that reflecting over the x-axis and the y-axis will be equivalent to an 180° counterclockwise rotation.

Answer:

a) n=\frac{0.76(1-0.76)}{(\frac{0.01}{1.64})^2}=4905.83  

And rounded up we have that n=4906

b) For this case since we don't have prior info we need to use as estimatro for the proportion \hat p =0.5

n=\frac{0.5(1-0.5)}{(\frac{0.01}{1.64})^2}=6724  

And rounded up we have that n=6724

Step-by-step explanation:

We need to remember that the confidence interval for the true proportion is given by :  

\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}

Part a

The estimated proportion for this case is \hat p =0.76

Our interval is at 90% of confidence, and the significance level is given by \alpha=1-0.90=0.1 and \alpha/2 =0.05. The critical values for this case are:

z_{\alpha/2}=-1.64, t_{1-\alpha/2}=1.64

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

The margin of error desired is given ME =\pm 0.01 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

Replacing we got:

n=\frac{0.76(1-0.76)}{(\frac{0.01}{1.64})^2}=4905.83  

And rounded up we have that n=4906

Part b

For this case since we don't have prior info we need to use as estimatro for the proportion \hat p =0.5

n=\frac{0.5(1-0.5)}{(\frac{0.01}{1.64})^2}=6724  

And rounded up we have that n=6724
