which distribution has the greatest spread.?!

Consider circle h with a 3 centimeter radius. if the length of minor arc what is the measure of zrst?

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

Standard deviation of 19,29,21,22,23
