Imagine a company of 200 staff. The manager believes that, in his company, he can predict staff' salary (USD) from the number of years of their education. The regression equation is Y'(salary)=bX(years of education)+A. After analyzing the data for all 200 employees, he found the correlation coefficient (r) between salary ($) and number of years of education is 0.25 and the SSY is 20. What's the estimated error of the estimate? Ο 0.306 0 0.6

(b) Now let's look at relating the values of some trigonometric functions for the two angles. Write $ \cos (2 \pi-0.35 \pi), \sin (2 \pi-0.35 \pi) $, and $ \tan (2 \pi-0.35 \pi) $ in terms of $ \cos (0.35 \pi), \sin (0.35 \pi) $, and tan $ (0.35 \pi) $, respectively. \[ \begin{array}{l} \cos (2 \pi-0.35 \pi)=\text { (Choose one) } \nabla \\ \sin (2 \pi-0.35 \pi)=\text { (Choose one) } \nabla \\ \tan (2 \pi-0.35 \pi)=\text { (Choose one) } \end{array} \] (c) Consider the equations in part (b). Replace $ 0.35 \pi $ on both sides of each equation with some angle $ \theta $ measured in radians. Are the equations still true no matter what angle $ \theta $ is chosen, as long as the tangent values are defined? Choose the best answer below. The equations in part (b) are true for $ \theta=0.35 \pi $, but they are not true for some other angle $ \theta $, even when the tangent values are defined. The terminal point for $ 2 \pi-\theta $ and the terminal point for $ \theta $ have the same $ x $-coordinate, but one is the reflection of the other across the $ x $-axis. So the equations in part (b) are true no matter what angle $ \theta $ is chosen, as long as the tangent values are defined.
