Interpret an r value of -0.82.?
961818
If x and y have a strong negative linear correlation, r is close to -1.  An r value of exactly -1 indicates a perfect negative fit.  Negative values indicate a relationship between x and y such that as values for x increase, values for y decrease. \n\nSo I would say that x and y have a strong negative linear correlation.  \n\nTaking r^2 = 0.6724 = 67.24% of the total variation in y can be explained by the linear relationship between x and y.  The other 32.76% remains unexplained.

x = -7\n\nMultiply two negatives and you get a positive

Mutiply $28 by 0.30, then subrtact 28 again, and that should tell you how much it is. ($19.60. It will come up as -19.60 though, just ignore the negative)

something close to zero

r is probably 27 and t is 8. Here's my reasoning:\n\n18 * 18 * 18 = r * r * t\n5832/r = r * t\nLets factorize 5832\n5832 = 27 * 27 * 8\nAnd Since 27 > 8, it can be accepted as the solution.\n\nI don't know if this is the correct way of doing it. Anyway, in my opinion worth a shot.

It printed this for me 0♦8\n\nHope this Helps.\nGood Luck!!!

I think it is 0.5-0.78

x-6 is greater than, or equal to -12 is what it reads. \n\nx is then -6 or more. (i.e.- -5,-4,-3.....)

you use the 10^x key\n\nthe antilog of -4.82 \n= 10^(-4.82) = 1.514 * 10^(-5) = 0.00001514\n\ntype in -4.82 and hit the 10^x key (it's usually right above the log key, which mean you hit the 2nd function key then log)

Well, I can see that one possible solution is r = 0, and my calculator says the other answer is r = 0.0809394063, so hopefully that helps...

I'm sorry, but how could you not know this?\nThis is basic elementary math and if you don't know how to round you are in trouble.\nIt's 0.1 by the way

Working above is good until this step:\n\n2 + 0.8x >0.9(x + 6)\n2 + 0.8x >0.9x + 5.4)\n0.1x > -3.4 ← Symbol error in this line\n\nShould read 0.1x < -3.4\nie x < -34
