Solve this one in exactly the same way as I solved the one
that you posted 1 minute before this one.

--  add up all the ' r 's .

--  add up all of the just-plain-numbers

This time, the answer looks like  9r .

You should spend a few minutes with it so that
you know where this answer comes from.

Which characteristics describe the scatterplot? check all that apply.
FrozenT [24]

The characteristics described in the scatterplot are B. positive correlation D. weak association E. linear.

<h3>What are the condition for Correlation?</h3>

1. Negative Correlation:

The correlation is achieved when either or both values of x and y on the graph decrease.

2. Positive Correlation

The correlation is achieved when the slope (value) of both x and y increases.

3. Strong Correlation

This is achieved when there's uniformity in slopes x and y.

4. Weak Correlation

This is achieved when there are no uniforms in slopes x and y

5. Linear

Linearity is achieved when the data pattern is linear (straight)

6. Nonlinear

Non-Linearity refers to whether a data pattern is curved.

We can see that the characteristics described in the scatterplot are B. positive correlation D. weak association E. linear.

What is the value of x in the circle below? If necessary round your answer to the nearest tenth. I AM FAILING THIS CLASS I JUST
emmainna [20.7K]
Since we know that the 38 is being bisected (which we can tell by the fact that the line hits it perpendicularly), we know that from the intersection to the edge of the circle is 19. From this we can create a right triangle in which the legs are 10 and 19 and the hypotenuse is a radius of the circle. Since x is also a radius of the circle, all we have to do is use that information to find the hypotenuse using the Pythagorean Theorem and we have x. 

Pythagorean Theorem
a^{2} + b^{2} = c^{2}
10^{2} + 19^{2} = x^{2}
100 + 361 = x^{2}
461 = x^{2}
x = \sqrt{461} or about 21.47
