How many different ways can six numbers be chosen from 42 numbers in a lottery game? How does the answer compare with the number of different ways 36 numbers
can be chosen from 42 numbers, explain your answer?

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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.
