Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. x 0 3 4 5 12
y 8 2 6 9 12

a. y^=4.98+0.425x
b. y^=4.98+0.725x
c. y^=4.88+0.625x
d. y^=4.88+0.525x

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
