No doubt your text advises how to arrive at a best-fit exponential model. The two graphing calculators I used gave different answers. The first one modeled the function as
y = 398.494(0.50526)^x
For x = 7, this model gives y = 3.35

The second calculator, a TI-84 work-alike, modeled the function as
y = 422.110(0.48896)^x
For x=7, this model gives y = 2.82

Using the first and last data points only, the model is
y = 200(0.06)^((x-1)/4)
For x=7, this model gives y = 2.94

Using yet another calculator to do linear regression on the log of y, the function is modeled by
y = 10^(2.62543-0.31073x)
which is another way to write the function produced by the TI-84 work-alike.

So, the technology I used gives a couple of reasons to choose
  A. 2.86
and a couple of reasons to choose
  C. 2.95

Of the models shown here, the ones with the lowest mean absolute deviation and the least squared error were the ones that produced the highest values of y for x=7, suggesting 2.95 is the best choice.


It would be advisable to use the procedure described in your text.

How many times larger is 3.19 x 10^8 than 8.23 x 10^5? SHOW YOUR WORK!!!
svet-max [94.6K]

In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.

So:

\frac{3.19*10^8}{8.23*10^5} =387.6063183

I'm not sure how much you want to round to,  but the answer is 387.6063183 times.

You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:

8.25*10^5*387.6063183=3.19*10^8
