12 cm is your answer
you just multiply 2 times 6 which is 12
the picture in the attached figure
we know that
in the right triangle FON
sin F=opposite side angle F/hypotenuse
in this problem
opposite side angle F=ON--------> 9 units
Hypotenuse=FN--------> 18 units
so
sin F=ON /FN-------> sin F=9 /18
therefore
the answer is the option
B.) sin F 9/18
Answer:
328 and the last one is 260
Step-by-step explanation:
i just did the question :p
A transformation of the plane is an isometry if, for all points X and Y, the distance between the image points X' and Y' equals the distance between X and Y. In other words, an isometry is a transformation which preserves distance
The expected number of cards from the card deck that will be strictly between the two jokers is

<h3>What is
card deck?</h3>
The most popular deck of cards used today is a normal 52-card deck of French-suited playing cards. [a] It is the only standard pack[b] used for playing cards in English-speaking nations; but, in many other nations throughout the world, it is used alongside other traditional, frequently older, standard packs with various suit systems, like those with German-, Italian-, Spanish-, or Swiss suits. The English pattern pack is the only one widely accessible in Britain and America and the most popular pattern of French-suited cards globally. The Belgian-Genoese pattern, which was created in France but is also used widely in Spain, Italy, the Ottoman Empire, the Balkans, and much of North Africa and the Middle East, is the second most popular.
Let all pairs of the positions (m,n) of the jokers are equally likely

the expected value will be

Therefore, the expected number of cards that will be strictly between the two jokers is
