PLEASE HELPPP MEEE THIS IS VERY IMPORTANT THANKSS The diagram shows a triangle ABC. The size of angle CAB is 55° and the length of AM is 10 m,
where M is the midpoint of AB. Triangle CMB is isosceles with CM = MB.
(a) Write down the length of MB
(1)
(b) Find the size of angle CMB
(2)
(c) Find the length of CB

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
