Answer:

43°

Step-by-step explanation:

Calculating for the measure of angle C using

<h3>sine rule</h3>

\frac{sin18}{9}  =  \frac{sinc}{20} \\ sinc =  \frac{sin18 \times 20}{9}  \\ sinc = 0.6867 \\ c =   \csc(0.6867)   \\ c = 43.3869 \\ c = 43 \: degrees

kkurt [141]

Answer:

0.097 is the probability that the entire batch will be rejected

Step-by-step explanation:

The total number of CDs = 6500

Number of defective CDs  = 110

Number of good CDs = 6500-110 = 6390

Out of this batch, 6 are randomly selected, then the probability that the entire batch is rejected is  

1 – [probability of accepting the entire batch]

1 – [6390/6500 * 6389/6499*6388/6498*6387/6497*6386/6496*6385/6495]

= 0.097

<u>Quadrilaterals</u> are <em>plane shapes</em> that are <u>bounded</u> by four <u>straight</u> sides. Thus, the required answers to the questions are:

46. True. Other examples include kites, rhombus, etc.

47. False.

46. When a <em>plane shape</em> is <u>bounded</u> by four <u>straight</u> sides of equal or different lengths, it is called a  <u>quadrilateral</u>. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual <u>properties</u>.

Thus the required answer to question 46 is; <u>True</u>. It can be observed that with respect to their <em>individual properties</em>, other <u>quadrilaterals</u> which have a pair of <em>opposite angles</em> to be <u>equal</u> include: kite, rectangle, rhombus, etc.

47. A <em>ray segment</em> is a given <u>line</u> that <u>points</u> or <u>heads</u> in a specific direction. So that the direction in which the ray moves is very<em> important</em>.

Thus in the given question, the <u>required</u> answer is; False. This is because the<u> two</u> given rays are moving in opposite directions. Though the two rays may have the <u>same</u> length of the <u>segment</u>.
