An exponential regression equation is in the form $y=a(b)^x$ . When you turn on your stat plot in your calculator and then enter those values into L1 for x's and L2 for y's, your calculator uses those values as coordinates to write an equation of best fit. The stat button is used for this. Arrow over to Calc and press enter and it will give you the equation of best fit for these data. Our equation is $y=11.55(1.85)^x$ . The coefficient of determination is .98 so it's a really close fit.

A word to the wise: It's <span> f(x)=125(0.9)^x, where ^ represents exponentiation.

In this case the ave. value over the interval [11, 15] is

125(0.9)^15 - 125(0.9)^11
------------------------------------- = (125/4) [ 0.9^15 - 0.9^11)
15 - 11 = (31.25) [ 0.2059 - 0.3138 ] = a negative result
= (31.25)(-0.1079) = -3.372 (av. r. of c.
over the interval [11,15] )

Do the same thing for the time interval [1,5]. Then compare the two rates of change.</span>

) a pair of fair dice is rolled. what is the probability that the sum of the top faces is a number 10 or greater?

andrezito [222]

Possible number combinations are 1,1 2,1 3,1 4,1 5,1 6,1 1,2 2,2 3,2 4,2 5,2 6,2 1,3 2,3 3,3 4,3 5,3 6,3 1,4 2,4 3,4 4,4 5,4 6,4 1,5 2,5 3,5 4,5 5,5 6,5 1,6 2,6 3,6 4,6 5,6 and 6,6. of those 36 number combinations the ones that add up to more than 10 include: 4,6 5,5 5,6 6,4 6,5 6,6. thats 6 number combinations. 6/36 of the possible sums of the top faces equal out to 10 or more. 6/36=1/6=0.166666666666666666666666(repeating) and to put that in a percentage, 16.7%
the probability is 16.7%
Hope this helps.
