So far, we have found that both triangles and squares work in tessellations. Can you think of any polygons that would not work? How about the pentagon? Try to visualize it. In a tessellation, each vertex would be the connecting point for a total of three pentagons. If each angle in a regular pentagon measures 108°, does it work? What reading strategy would help you read this paragraph more fluently?

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2

Can someone tell me if this is perpendicular? !
