A polygon is a closed figure formed by three or more straight lines called line segments.

<h3><u>Solution:</u></h3>

A polygon is a closed figure formed by three or more straight lines called line segments.

It is formed with only straight lines; if any curved line is used to form a closed figure than it will not be termed as a polygon

A polygon can be classified on the basis of a number of sides and measure of angles

Classified by Measuring the Angles:- Regular, irregular, concave , convex, quadrilateral and pentagon

On the basis of sides it can be a triangle having 3 sides, quadrilateral having 4 sides, pentagon having five sides and so on

A random sample of 4000 college students yielded 2250 who are in favor of banning Hawaiian shirts. Estimate the true proportion

Andreas93 [3]

Answer: (0.5496, 0.5754)

Step-by-step explanation:

The confidence interval for population proportion (p) is given by :-

$\hat{p}\pm z*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$ , where $\hat{p}$ = Sample proportion , n= sample size , z*= Critical z-value.

Let p be the proportion of all college students who are in favor of banning Hawaiian shirt.

Given, A random sample of 4000 college students yielded 2250 who are in favor of banning Hawaiian shirts.

i.e. n=4000

$\hat{p}=\dfrac{2250}{4000}=0.5625$

z-value for 90% confidence level is 1.645

Now , 90% confidence interval for p would be :

$0.5625\pm (1.645)(\sqrt{\dfrac{0.5625(1-0.5625)}{4000}})$

$=0.5625\pm (1.645)(\sqrt{0.0000615234375})\\\\=0.5625\pm (1.645)(0.00784368774876)\\\\\approx0.5625\pm0.0129\\\\=(0.5625-0.0129, \ 0.5625+0.0129)\\\\=(0.5496,\ 0.5754)$

Hence, the required 90% interval = (0.5496, 0.5754)

What is the unit rate of 360 customers in 30 days

ad-work [718]

To find a unit rate, we need to divide the unit (days) by itself, and the x per y (customers) by the unit. In this case, we will be dividing 360 (number of customers) by 30 (days). When we do this, we can see that there are 12 customers per day.
