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?

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
