<span>Pearson's correlation coefficient 'r' measures the degree to which two variables are correlated. The value is between -1 and 1. Negative values correspond to negative correlation (as one variable increases, the other variable decreases) whereas positive values correspond to positive correlation. The larger the absolute value of r, the closer a correlation graph resembles a set of points on the same line. Therefore, if two variables are completely correlated, the correlation value is 1 or -1, depending on whether the correlation is positive or negative.</span>

Answer:

Is the question to develop the equation for the straight line shown?

If so,<u> y = (3/4)x + b</u>

Step-by-step explanation:

Look for an equation with the form y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).

Calculate Slope using the Rise/Run.

Pick any two points.  I chose (-4,0) and (4,6).

Going from left to right:

Rise = (6 - 0) = 6

Run = (4 - (-4)) = 8

Slope is Rise/Run, 6/8 or 3/4

So we have:  y = (3/4)x + b

We can see that the y-intercept, b, is 3 (the value of y when x = 0).

The full equation becomes :<u>  y = (3/4)x + 3 </u>

Lera25 [3.4K]

Answer:

(\frac{A}{B+C} )(DE)

Step-by-step explanation:

You're multiplying two factors together (because at the start, it says the product of)

The first factor is the quotient of A, and the sum of B and C, so A divided by (B + C)

The second factor is whatever the product of D and E is, so you have to multiply those together first
