Anormal die (numbered 1-6) is fair if each outcome is equally likely. therefore a 1, should come up of the time. if a fair die is rolled 360 times we would expect a 1 to come up 60 times since (1/6*360=60) if x represents the number of times "1" is rolled then\left | (x-60)/\sqrt{50} \right | < 1.95 gives reasonable range for the number of times a "1" will come up in 360 rolles. if we roll the dice 360 times and get "1" 30 times, is our die a fair die? show all work

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220

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.
