Assuming that the probability of giving birth to a boy or girl is 50% (that is equally likely to have a boy or girl), find: a. the probability that my fourth child is my second son. b. the probability that my tenth child is my sixth son.

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

True or false? a circle could be circumscribed about the quadrilateral below.

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
