Which best describes the strength of a model with an r-value of 0.29

Mathematics

The <u>correct answer</u> is:

It is not a very strong fit.

Explanation:

The r-value, or correlation coefficient, tells us how closely our model fits the data.

The r-values range from -1 to 1.  -1 is a perfect fit of a decreasing model; 1 is a perfect fit of an increasing model.  0 is no fit at all.

Since our r-value is 0.29, this is much closer to 0 than it is to 1 or -1; this means it is not a very strong fit.

Which angle is coterminal with a 645° angle?
velikii [3]

Answer:

C

Step-by-step explanation:

Coterminal angles are angles that have a common terminal side.

So, given an angle θ, its coterminal angles will always be ±360°. This can be repeated.

We have a 645° angle.

Therefore, all values of the equation:

645\pm 360n

Where <em>n</em> is an integer is coterminal with our original angle.

Letting <em>n</em> = 1 and using the negative case, we acquire:

\Rightarrow 645-360=285

Therefore, an angle measuring 285° is coterminal with a 645° angle.

None of the other options can be reached by adding/subtracting 360.

Therefore, our answer is C.

How do you determine the limit algebraically?
eduard

Answer:

0.125

Step-by-step explanation:

This is a standard calculus question. If you search out L'Hopital's Rule you will find that there are only Calculus examples present. If you use calculus, the answer comes to 1/8. The only way I can think of doing this without the use of Calculus is to let x = something very small -- say x = 0.0001 That approaches 0, but it is not quite = to 0.

So let's try it.

16 + 0.00001  = 16.00001

sqrt(16.0001) = 4.00000125

Now subtract 4

4.00000125 - 4

0.00000125

Now divide by 0.00001

0.12499998

which is close to 0.125.

If someone else can give you an answer that is "purer" than this one, take it.
