Apolitical scientist was interested in studying america's voting habits. so, he decided to make a least squares regression equation to predict the percentage of people that would vote for obama in 2012 based on the percentage of people that voted for obama in 2008. the least squares equation is y-hat = -4.599 +1.04x. the value of r-squared was 96.69%. what would be the value of r? group of answer choices 0.9669 0.9833 -0.9669 -0.9833 0.9349 -0.9349

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
