(last word) if variables x and y are positively correlated, this means that

if variables x and y are positively correlated, this means that

If variables x and y are positively correlated, this means that causation may or may not exist between X and Y

When there exists a positive correlation between x and y, the correlation coefficient (r) is greater than 0. It signifies that both variables move in the same direction or are correlated. When correlation coefficient is +1, it signifies that the two variables have a perfect positive relationship; when one variable moves higher or lower, the other variable moves in the same direction with the same magnitude.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
