Say that global temperatures could change over the next several decades and you have it on good advice that the change (in degrees Celsius) is equal to the percentage change in CO^2 use in the USA times .2 and then you would add the percentage change in CO^2 use in the rest of the world times .8. Over the time period the percentage change in CO^2 use in the USA is expected to fall with a uniform distribution between -10 and -6 percent and the percentage change in CO^2 use in the rest of the world has a normal distribution with mean of 2.2 percent increase and a standard deviation of .1. (Think of 2.2 percent, for example, as 2.2 and not 0.022 in this instance.) 1. Simulate 1000 trials of global temperature change. 2. In your simulation, what is the probability that global temperatures will DECLINE?

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

the answer to question 1 is -8, 28.

step-by-step explanation:

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

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.
