<u>Elements in a Circle</u>

Before drawing the 8 required elements in the circle, let's recall some basic definitions:

Chord: A straight line whose extremes both lie on the circle
Tangent: A straight line that touches the circle in one point and is perpendicular to the radius at the point of tangency
Radius: It's a straight line from the center of a circle to its circumference
Secant: It's a line that that intersects the circle in exactly two points
Point of tangency: Is the point where the tangent line touches the circumference
Diameter: It's a straight line from one point to the circle going through the center.
Minor arc: Is an arc of a circle that measures less than or equal to 180 degrees
Mayor arc: Is an arc of a circle that measures more than 180 degrees

Please refer to the image below to see all the elements described above

LekaFEV [45]

Answer: $735.49

Step-by-step explanation:

Given, the price of 10 tolas gold bought from American market = $553

Custom duty charge = 20%

VAT = 13%

Custom duty charge = 20% of $553

= 0.20 x 553 [we divide a perecntage to convet it into decimal]

= $110.6

VAT = 13% of $553

= 0.13 x 553

= $71.89

Selling price = Original price +Custom duty charge + VAT

= $553+$110.6+ $71.89

= $735.49

Hence, it should be sold at $735.49 .

goblinko [34]

2 classes of 21 students each
21 × 2 classes = 42 students in total
42 × 3 mins = 126 minutes for 42 students
10 mins for 2 class pics = 20 minutes
126 + 20 = 146 minutes = 2 hours and 26 minutes

It should take 146 minutes (2 hours and 26 minutes) to take all the pictures.

Which points are coplanar and noncollinear

yaroslaw [1]

Answer:

Non-collinear points: These points, like points X, Y, and Z in the above figure, don't all lie on the same line. Coplanar points: A group of points that lie in the same plane are coplanar. Any two or three points are always coplanar. Four or more points might or might not be coplanar.

vladimir2022 [97]

The confidence interval is
$0.59\pm0.081$

We first find p, our sample proportion. 118/200 = 0.59.

Next we find the z-score associated with this level of confidence:
Convert 98% to a decimal: 98% = 98/100 = 0.98
Subtract from 1: 1-0.98 = 0.02
Divide by 2: 0.02/2 = 0.01
Subtract from 1: 1-0.01 = 0.99

Using a z-table (http://www.z-table.com) we see that this value is associated with a z-score of 2.33.

The margin of error (ME) is given by
$ME=z\sqrt{\frac{p(1-p)}{n}}
\\
\\=2.33\sqrt{\frac{0.59(1-0.59)}{200}}=2.33\sqrt{\frac{0.2419}{200}}\approx0.081$

This gives us the confidence interval
$0.59\pm0.081$
