<em>The value of a correlation coefficient ranges between -1 and 1.</em>
<em />
<em>The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.</em>
<em />
<em>The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.</em>
<em />
<em>The weakest linear relationship is indicated by a correlation coefficient equal to 0.</em>
<em />
<em>A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.</em>
<em />
<em>A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.</em>

Given:
The given expression is

To find:
The two other equivalent expressions.
Solution:
We have,

Using distributive property, we get


So, one equivalent expression is
.
On further simplification, we get


Therefore, the second and fully simplified equivalent expression is
.
Option C:
We can find the value of PR using law of cosines.
Solution:
Given data:
∠Q = 18°, r = 9.5, p = 6.0
To find which length could be find in the triangle:
Law of cosines:

Substitute a = q, b = r, c = p and A = Q

If we substitute the values given, we can find q.
q = PR

Hence we can find the value of PR using law of cosines.
Option C is the correct answer.
Answer:
-infinity
Step-by-step explanation:
plug in numbers for x that is on the right side of the graph and you will see a trend that the larger x is the bigger y is(technically smaller because y would be negative due to the negative sign outside the square root) as x approaches inifity y approaches negative infinity.
So, you will put the numerator inside the symbol and the 2 outside of it so like
429.5
