<span>1.6. The Pearson Correlation Coefficient, otherwise known as r-value, must have a value between -1 and 1. It's used to measure how closely related two different variables are. -1 means negative linear correlation, 0 means no linear correlation, and 1 means positive linear correlation.</span>
Hi there!
We can use right-triangle trigonometry to solve.
We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.
cosθ = Adjacent/Hypotenuse
We can plug in what is given:
cos(28) = A/17
Solve for 'A':
17cos(28) = <u>15.01 ft</u>
